1、前 言

当今物理学界仍在不断寻地找物质的基本粒子,但基本粒子是什么?人们现在仍难以作出正确的回答,在易经里,我们知道:太极生两仪,两仪生四象,四象生八卦,八卦生宇宙万物。而太极者,无极也。这不就是零物质吗?我们知道光子的静质量是零,若这零物质是光子,那么光子不就是“最基本粒子”吗?我们知道无限小的极限是0,那么基本粒子的极限不就是光子吗?

同时,现在物理学家们又正在努力寻找宇宙的物理规律、物理常量,努力寻找物理的大统一理论。若我们确定了什么是最基本粒子,那么这最基本粒子的物理规律、物理常量就应与宇宙的物理规律、物理常量有着必然的联系。

现在的超弦理论被部分人认为是大统一理论,一个能在单独的包罗万象的协和的数学框架下描写自然界所有力的理论。在弦理论看来,弦是宇宙物质组成的最基本单元,所有的基本粒子如电子、光子、夸克、中微子都是它的不同具体形态。到现在为止,弦理论还只是一种假说,人类尚未观测到基本的弦。超弦论的实验验证和证伪存在着极大的困难,由于那些额外维度的空间被卷曲得如此之小,必需建造一个尺度大如银河系的粒子速器才行。

基于数学领域的哥德尔不完备性定理,在任何公理化形式系统中,总存留着在定义该系统的公理的基础上既不能证明也不能证伪的问题。也就是说任何一个理论都有解决不了的问题。因此,大统一物理不是包含所有各分枝物理的理论,而是各分枝物理的共同部份、基础部份。他应是简单的、优美的。

现本人试图从光子的角度为基本粒子、大统一物理的研究提出一个方向。本文是建立在旧有的理论(相对论、热力学定律)基础上的一个新的推论,而不是建立在一个新的假设之上。

2、信 息 的 量 化

香 农(Claude E.Shannon)指 出,信 息是对体系的统计描述的一种性质,是体系的一种基本属性,即它们的组织化程度的度量。香农证明的一个基本定理表明,一个体系的信含量等于对该体系的完备的统计描述进行编码所需的二进位数最少位数。一个体系的信息所反映的是其可能的存在状态的量值。量度信息 的 单 位 是 比 特(bit);一 比 特 信 息 是两个相等的可能性之间决定一个所需的信 息 量。如 某 个 体 系 有2r 个 可 能 的 存 在状态,那它的信息就是 r 比特。对可能的存在状态的观测受测

不准原理、测量水平等所制约,不同测量水平所测量的信息记录是不同的。在一个完全封闭的系统里,可精确地描述出大量的态,我们常称之为微观态。在量子力学里,这就是系统可能的量子态。这些微观态根据粗粒化区分的不同性质,分 类 聚 集 到 一 块 儿(可 称 之 为 宏 观 态)。在一给定宏观态中的微观态可以看成是彼此等价的,所以我们通常只关心微观态的数目。

同时,不知道一团物质的终极组成部分或其最深层次的结构,我们就无法计算其终极信息容量,也无法计算其香农熵。但是,我们可以找到能计算其信息容量的最深层次的结构。按照微型化技术目前这样快的发展速度,我们可以设想将来某日夸克能被用来存储信息,也许是一个夸克一比特。

3、香 农 熵

香农熵反映了在一个随机试验(或随机变量)的不确定性。一个随机试验可用:

表示。其中 1,2,„..,n为可能发生的结果,pi为i发生的概 率。X 的 不 确 定 性 大 小取决于 n 的大小与 pi 分 布 的 均匀 程 度。这 个 不 确 定 性 是(p 1 , p

一个 函 数,记 为 H,它 具 有 如 下 性 质 : 2 ,„ ,p n)的(1)对称连续性,即H(p1,p2,„,pn)是(p1,p2,„,pn)的对称连续函数;(2)H(0, 1)=0;

(3)如q=p n +p n + 1 则 H(p 1 ,p 2 ,„ ,p n ,p n + 1)=H(p 1 ,p 2 ,„ ,p n-1 ,q)+qH(p n /q ,p n + 1 /q)。通过数学的推导,得香农熵:

log 的 底 我 们 取 2,H(X)的 单

位 是 比 特(bit)。如(X,Y)为 二 元 随 机 变 量,取 值 为(x ,y),x=1 ,2,„,m,y=1 ,2 ,„,n ;联合概率分布为pij,则 联 合 熵 为 :

称 H(Y| X)= H(X,Y)- H(X)为 Y 关于 X 的条件熵,它表示条件不确定 性。当 Y 不 依 赖 于 X 时,即 X、Y 相 互独 立 时 H(Y| X)=H(Y),得 :

H(X,Y)= H(X)+H(Y)

从概念上来说,热力学熵和香农熵是等价的,当香农设法量化一条消息中的信息时,他自然而然地得出了一条和玻尔兹曼一样的公式。玻尔兹曼熵所代表的不同组成方

式的数目反映了为实现某种特定组成方式所必须知道的香农信息量。

4、熵 和 信 息 的 一 个 守 恒 定 律

熵和信息有一个守恒定律,就是一个体系的信息与熵的和保持守恒,并等于该体系的最大信息或最大熵。即:H+I=H m a x =I m a x =const

H 和 I 表 示 熵 和 信 息 的 值,Hmax 和

Imax表示熵和信息最大的可能值。

熵增加原理可描述为信息减少原理,即是一个孤立体系的信息一定能达到所能达到的最小信息。

熵是一种不确定性的量度。当信息被获得和记录下来,需要消耗能量,这时不确定减少了,而与此同时记录中的信息增加了。当记录被擦掉时,记录中的信息减少了,但整个封闭系统情形的不确定至少增加了相同的数量。

同 时,熵 与 粗 粒 化 有 关,即 与 被 描 述系统详尽的程度有关。的确,一个体系如果所有的细节都考虑了的话,那么在数学上就可以认为熵不会再增加,熵将保持不变。但事实上,一个分为许多部分的体系常常只用它的某些变量来描述,这些比较少的变量的有序性会随着时间而散失到其他变量中去,于是前者也不能再看成是有序的了。这就是热力学第二定律的真正意义。

无论是对信息熵的记录,都与测量水平、所考虑的变量有关。当我们用更准确的测量、考虑更多的变量,就会发现更微观的信息。

5、宏 观 信 息 向 微 观 信 息 的 转 换

概率的均匀分布和不均匀分布表示了一个体系的信息含量方面的一个质的差别。我们将空间分

2r 个“宏 相 格 ”,我们把宏观信息确定为这些宏相格所对应的一组概率所需的信息;确定概率在宏相格内部的分布所需的信息,则定义为微观信息;但实际上,我们可把每个“宏相格”分割成 2q“ 微 相 格 ”,我们可以把微观信息确定为所有这些微相格所对应的一组概率所需的信息。同时,我们可以把宏观信息看作是我们对体系的统计性质的知识,而把微观信息看作是对各个微观粒子的具体知识,具体来说就是微观信息代表了我们对各个粒子的速度之间的相互关联的了解。

我们设想一个假想实验,在空气完全静止的封闭空间的一角,放置一瓶密封 香水。瓶密封香水放在空间的一个“宏相 格 ”中,它 占 据 的 体 积 是 1/2 r,其 宏观 信 息 就 是 r; 随 着 时 间 的 推 移 我 们 看不到宏观信息的变化,这是由于它

在一个制约条件下(如瓶被密封等)。如把瓶盖打开,随着时间的推移,香水分子就会挥发,其宏观信息不断减少,直至全部宏观信息转变为微观信息,总的信息量并没有变化。我们还可以把微相格再细分下去,随着时间的继续推移,用更准确的测量、考虑更多的变量,就会发现微观信息就向着更微观的信息转变。

若我们把更微的相格的长度确定为Planck 长 度,根 据 测 不 准 原 理,我 们 知道,这将是最微观的信息。这时,若把这样的更微的相格再向下细分,那么,信息就消失在量子涨落中,因为我们不可以再测量了;或者说,根据信息减小原理,当这个最微观的信息继续减小时,信息就消失在量子涨落中了。同时,一个名义上孤立的体系同世界其余部份的不可避免的相互作用是以微小的随机扰动的方式来进行的,这的微扰破坏粒子之间的关联,能消耗微观信息。

宏观信息可转变为微观信息,反之亦然。从量子涨落中产生信息,产生有信息的基本粒子,通过这些粒子的相互作用、相互关联就产生了更多的信息,产生了宏观信息,但这个过程需要消耗能量。

6、光 子 是 物 质 的 最 基 本 粒 子

我们知道,电子有 22 个 可 能 的 存 在状态(它有两种电荷两种自旋状态,是现在的测量水平下所能测到的),要指定具体什么电子,需要 2 个二进位数,所 以 单 独 一 个 电子 的 信 息 是 2bit。对 于光子,自旋方向有平行与反平行于物质运动方向两种,他最少的可能存在状态 2 1 个,所 以 单 独 一 个 光 子 的 信 息 是应是1bit,这 是 现 在人 们 的 测 量 水平所 观 测得到的。对于由大量光子组成的一个孤立体系,左旋与旋相等混合并均匀地分 布,这 时 这 个 体 系 的 信 息 是 0bit。

基本粒子中信息容量最小的信息应该 是 1bit,现 在 我 们 来 看 看,在 测 不 准原理制约下,基本粒子中信息最小的粒子是不是光子。我 们 知 道 能 量 与 质 量 是 一 回 事。设 Q为热量、E 为能量、T 为绝对温标、m 为质量,S 为势力学熵。考虑在一个与外界没有作功的系统中,据热力学第一定律,得:

dQ=dE=dm

dS=dE/T 由能量均分原理

E/T=const

dE/E=d(lnE)若

dS≥ 0,则 : dm≥ 0

考虑一个非平衡的系统,它可以被分

成无限多个近似平衡的小系统,由于熵与

质量的可加性,我们完全可以相信存在 这 么 一 个 体 系,上 式 仍 然 成 立。而 且,在一个孤立的不可逆体系中,只要有足够的时间,熵一定能达到最大值,信息一定能达到最小值。在测不准原理制约下,我们可以找出能计算其信息容量的最深层次结构的最微观的信息。在这个最深层次的结构下,当系统信息达到 0时,微观系统的单一粒子就一定会存在基本粒子中信息最小的粒子。由相对论,得:dv≥ 0v 是组成这个特殊的孤立的不可逆体系 的基本粒子的速率。

这说明了熵增加的方向就是使组成这粒子的最基本粒子的速率最终达到光速,粒子最终分解成静质量为零的最基本粒子,也就是说,在一个完全孤立的没有给定任何制约条件的物理体系中,熵增加原理就是使其系统中的总静质量最终为零。从相对论可得知,一个静质量不为 0 的物质是不可能被加速到光速,但我们认为它可以分解为光速的光子。因而,光子是静质量为零、信息为bit 的 粒 子,它就 是 物 质 的 最 基 本 粒 子。也就是说作为速度极限的光子,也是信息最小的粒子,是基本粒子无限细分的极限。

另一方面,我们可以在光子建立参考系观测一个孤立的物理体系,据相对论,我们会发现,组成这物理体系的全是速度为光速的粒子,即光子。当然,一般地,人们不会在光子建立参考系来观测一个孤立的物理体系,因为这是极端的情况。但是,一个普适的物理定律若不可以在极端的情况下使用,又何以普适呢?

无论从信息减少原理、熵增加原理以及在光子建立参考系观测,我们都可得到结论:光子是物质的最基本粒子。

7、信 息 和 静 质 量

现 在 我 们 设 两 个 光 子 A、B,它 们 以光速运动着,设其动质量(总动能)为m A、m B。由 于 A、B 有 动 质 量,还 会 有 电磁 等 一 些 特 性,所 以 当 A、B 结 合 成 一 个基本粒子――具有“ 刚性” 的粒子时,光子之间存在着相互作用,这就产生了位能。这 时,我 们 设 A、B 的 位 能 为V A *、V B *,总 动 能 为 m A *、m B *,那 么 A、B 的总能量就是:V A *+ m A *、V B *+ m B *。把 A、B 作 为 一 个 总 体 M,那 么 M 的 总 静质量 m 为:m=V A *+ m A *+V B *+ m B *。由最基本粒子组成的物质的静质量即固有质量就是物质内部各粒子间的相互作用而产生的位能与物质内部各粒子间的相互运动而产生的总动能之和。

在一个完全孤立的没有给定任何制约条件的物理体系里,由信息减少原理,随 着 时 间 的 推 移,其 信 息 最 终 为 0bit,可以说是没有信息,这时,整个物理体系 的 总 静 质 量 亦 为 0。当 一 个 物 理 体 系有静质量时,就说明它内部存在光子及粒子间的相互作用,它产生了信息;反之 亦 然,物 理 体 系 存 在 信 息(>1bit)也说明它有静质量;物质信息和静质量都是由其内部的各光子及粒子间的相互作用产生的。如一个电子,它有信息(2bit),亦 有 静 质 量。但 到 现 在 为 止,我们仍不能说有多少信息就有多少静质量,而这需要进一步的研究。

光子通过一定的方式组成物质,通过光子之间的相互作用(可以通过力的作 用)、通 过 转 化 而 成 为 一 个 有 静 质 量的粒子,这时候,亦就产生了位能,产生了新的息,产生了静质量,但也许我们已不能观测到其内部的单一光子了。电子--反电子对可以湮灭转化为一对光子,同样,若干个光子是可以转化为电子的。

8、整 个 宇 宙 的 微 观 信 息

首先,我们把宇宙表示为一条无限长的“ 直 线 ”模 型。为 了 体 现 测 不 准 原 理,我们必须把一维直线分割成长度相等的小段,小段的长度代表单个粒子的位置所能做到的精确度。如果我们又确定占据 每 个 小 段 的 粒 子 数 目,那 么,这 个“ 直线”宇宙就可以用一个由“占有数”构成的、两端都开放的无限数列来表示。于是微观信息就可以这样定义:它使我们能够区分两列具有相同统计性质的(这样的占有数数列即宏观)。现在我们来试图证明这两具数列是相同的。我们从一列占有数数列中选出任意长度的一个子数列,在一个无限数列中,任何有限长度的子数列都将重复出现无限多次。大数定律保证我们经过有限次尝试之后就一定能找到相同统计(即宏观)性质的这样的占有子数列,而且,不管我们选出的子数列有多长,只要长度有限,我们就一定能找到。

我们把上述论证推广到三维无限宇宙中去,只要满足强宇宙原理和局部宇宙结构的大小是有限的要求,那么,把宇宙作为一个整体来看其性质全是统计性(即宏观)的,它的微观信息根本不存在。

9、光 子 的 物 理 特 性、物 理 常 量 影 响 着宇宙的物理规律与物理常量

光子具有量子化,它的能量为:m=hv/c 2其 中 h 是 Planck 常 数,v 是 频 率。由 光 子 的 量 子 化,我 们 认 为 光 子 是 可以合并和分解的。但无论如何,只

要静质量为零就是光子。就单一粒子而言,光子都具有相同的物理特性,只有在不同的场里才表现不同的物理特性。

光 子 具 有 量 子 性、电 磁 特 性 等 等,光速是它的物理常量。宇宙是由光子组成的,所以光子的物理特性、物理常量影响着宇宙的物理规律与物理常量。若整个宇宙由很多个小宇宙组成,那么每个小宇宙中光子的物理特性、物理常量影响着这个小宇宙的物理规律与物理常量。无论是何种情形,宇宙中的任何事物似乎都是根据科学定律的演化所确定的,而这些则由光子的物理特性、物理常量影响着。对光子物理特性、物理常量的研究应是现代物理的方向。

1.Preface

Physicists have been searched for elementary particleof matter.Bat what is elementary? People find it hard toanswer this question.From china ancient books--TheBook of Changes, we know that Taiji produces two Yi.Two Yi produce four quadrant, four quadrant produceeight diagrams.Eight diagrams produce all the things inthe universe.Grand means endless.But the taiji is thegreat void, isn’t it that ZERO matter? We know thatphoton’s rest mass is zero.If the ZEROmatter is photon,isn’t it that photon is “the ultimate elementary particle ofmatter”? We knowthat infinitesimal limit is zero.If so,isn’t it that ultimate elementary particle of matter isphoton?

Meanwhile, nowadays physicists are trying hard tosearch for the physics law, the physical constants and thetheory of grand unification.If we have defined what theultimate elementary particle is, we’re then sure that thephysics law and the physical constants of the ultimateelementary particle have certain relation with thephysics law and the physical constants in the universe.The modern superstring theory is considered as grandunification by some people, a theory which includeseverything and describes every natural power under themathematical framework..In the view of superstringtheory, string is the most basic unit and all the elementalparticle which formed the universe, for example,electron, photon, quark and neutrino are its specific states.Up till now, the string theory is only a scientifichypothesis.The human being haven’t observed the basicstring, yet.The superstring theory is very hard to beproved through experiment, since the extra dimensionspace is curled so limited, people have to build a particleaccelerator as enormously as the galaxy to do theexperiment.According to Kurt Friedrich Göde’s un-completenesstheorem on math field, in any self-evident axiom formsystem, there always exits a problem which could not beproved right or wrong of its definition.That’s to say anytheory has some unsolved problems.Therefore, thegrand unification doesn’t include all the branch physicstheories, while it becomes a common andbasic part ofall the branch physics.So it must be the most simple and elegant one.I try to take a lead for the study of elementary particleand the grand unification.This essay is based on theexisting theories(e.g.theory of relativity,thermodynamics law)and then it forms a new theory.After all, it isn’t built on a new hypothesis.2.Quantization of information

Claude E.Sannon pointed out information is a kind ofcharacteristic which describes the statistics of a system,is also a basic attribute of the system that they’re theorganized measurement.Shannon’s basic theorem showthat a system’s containing information equals to thefewest digits of binary system in which we code theperfect describing statistics.The information of a systemreflects its possible existing state magnitude.The unit ofinformation measurement is bit.Abit of information istwo equal possibilities but chosen one amount ofrinformation.Forexample,one certain system has 2possible states.Then its amount of information is r bits.To observe the possible states is restricted by theHeisenberg uncertainty principle and people’s measuringlevel.Different measuring levels lead to differentrecords of information.In a completesealed system, wecan describe lots of states precisely.We often call themmicro states.In the field of quantum mechanics, weconsider them as the possible system quantum states.These micro states gather together on different kinds dueto different sorts of coarse granulating(which could becalled macro states).In a defined macro state, microstates could be considered as equivalence, so we oftencare the numbers of micro states.At the same time, if we don’t know the finalcomponents of a matter or the deepest layer of structure,we could not count the amount of the information and could not calculate their Shannon entropy of thestructure.But we can find deeper layer structure inwhich we could calculate the information amounts.By the development of micromation technique, we canimagine that in the future quarks could be used to store information.May be a quark could store a bit of information.3.Shannon entropy

Shannon entropy reflects an uncertainty of a randomexperiment(or random variable).A random experimentcan be expressed as:

In the formula, 1, 2 ,…, n express the possible result,while pn shows i’s probability.X’s uncertain value is decided by n’s value and pn’s distributing even rate.The uncertainty is a function of(p1,p2,…,pn)and is marked as H.it has the next qualities:(1)Symmetric continuity.Viz.H(p1,p2,…,pn)is the symmetrical continuous function of(p1,p2,…,pn);(2)H(0,1)=0;(3)If q=qn+qn+1, then H(p1,p2,…,pn,pn+1)= H(p1,p2,…,pn,q)+ qH(pn/q,pn+1/q).Through the math deduction, we get the Shannon entropy: bit.log’s base is 2, and the unit of H(X)is If(X,Y)are the duality random variables, valued as(x,y), x=1,2,…,m , y=1,2,…,n.The unitedprobability distribution is pij, then their united entropies are:

We call H(Y|X)=H(X,Y)-H(X)as Y for X,s conditional entropy.It shows the conditional uncertainty.When Y doesn’t depend on X, Viz.X and Y are separately independent, H(Y|X)=H(Y).we get: H(X,Y)=H(X)+H(Y)

As is known from the concept, thermodynamics entropy has the same equipollence with the Shannon entropy.When Shannon tries to quantify the information from a information, he naturally gets a same formula as Boltzmann’s.Boltzmann entropy which represents different forming numbers reflects the amount of Shannon information which is ready for meeting a certain compound mode.4.A conservation law for entropy andinformation Entropy and information have a conservation law that in a information and entropy keep conservative, and equal to the biggest information or the biggest entropy.Viz.: H+I=Hmax=Imax=const

H and I refer to the values of entropy and information.Hmax and Imax refer to the most possible values of entropy and information.The entropy increase principle can be described as

the information decrease principle.Namely the information in a sole system can get to its smallest information.Entropy is an uncertainty measurement.When information is obtained and recorded, energy was used up.In this circumstance the uncertainty decreases.At the same time the recorded information increases.When the record is cleaned, the recorded information decreases.But the uncertainties in the whole closed system increase by the same amounts.At the same time, entropy has some relation with coarse granulating, Viz.it has something to do with the extent of the described system.Surely, if all the details of a system are considered, we think that their entropy won’t increase in the view of math again.So the entropy keeps constant.But in fact, if a system has many parts, we only use some variables to describe it.These smaller variables will add up to other variables due to their orderliness with the running of time.And then the former ones no longer become orderly.This is the concept of the second law for thermodynamics.Not only the record of information but also the record of entropy, its result has something to do with people’s measuring level and people’s considering variables.When we measuring more accurately and consider more variables, we will find out more micro information.5.The transfer from macro information intomicro information

Whether the probability scatters evenly or not shows that a system has distinguished information.We divide the space into 2 r “macro phases”.We look on the macro phase information as the needed informations by a group of probabilities which are corresponding with these phases.The probabilities which are distributed in the macro phases can be defined as micro information.In fact, we divide each “macro phase” into 2 q “microphase”.We look on the micro information as a group of corresponding messages needed by the probabilities.Meanwhile, we look on the macro information as the knowledge by which we understand the quality of the whole system.Then we look on the micro information as the knowledge by which we concretely understand every micro particle.In other words, micro information shows that we understand every particle’s related speed.Let’s imagine an experiment that in a corner of a close space we place a sealed bottle of perfume in it.The bottle of the perfume was then placed onto a “macrphase” of a certain space.And its cube is 1/2 of which the macro information is r with the running of time, we couldn’t see the changes of macro information, because it is under a restricted condition(e.g.the bottle is sealed.).If we take off the lid, with the time gone, the molecules of the perfume will escape from the bottle.And we know that the macro information is decreasing till all the macro information change into micro information.But the total amounts of information haven’t changed at all.We still can go on dividing the micro phases.With the time gone, we may use more accurate measuring method, and we may consider more variables.At last we can find that micro information will change into even more micro information.If we define the length of even more micro information as Plank length, according to the uncertainty principle, we know that these will become the most micro information.By now if we go on dividing the even more micro information, the information will disappear in the quantum fluctuation, because we couldn’t go on doing the measuring any more.In other words, according to the information decreasing principle, when the most micro information goes on decreasing, all the information will disappear in the quantum fluctuation.At the same time, a nominal sole system and the rest parts of the world will interact and they come to action by the way of random disturbances.These perlur batives will damage the relationship among the particles.Further more, they will consume the micro information.Macro information can change into micro information and vice versa.Information comes from quantum fluctuation and produces elementary particles with information.By the interaction and relation of these elementary particles, they will produce more information, and then produce macro information.But in this process, energy will be consumed.6.Photon is the ultimate elementary particle of matter

As we know an electron has 22 possible existing states(it has two electric charges and two spinning states, which is measured by people now).If you want to specify what electron it is, you need 2 digits of binary.So a sole electric, information is 2 bits.As for the photon’s spinning, it has two ways of motion which parallels the matter’s moving direction or opposite of it.Its least possible existing states are 2 1.So a sole photon, information is 1 bit which is measured by people now.For a sole system which is formed by lots of photons, their left and right spins are equal and scattering evenly.The whole system information is 0 bit.The least capacity of the information in an elementary particle is 1 bit.Under the

uncertainty law, among the elementary particles isn’t the least information particle photon?

We know that energy and mass are the same things.If Q for heat quantity, E for energy, T for Kelvin scale, for mass, S for thermodynamics entropy, we consider a system which has no power with the outer world, according to the first law of thermodynamics, we then get:

Obey the principles of energy’s equipartition, we get:

If >0,them dm > 0

Suppose a special in-equilibrium sole system, it can be divided into limitless approximate equilibrium small systems.Due to the fact that entropy and mass can be summarized, we absolutely believe there is such a system, the above formulas are acceptable.Further more, in a sole in-reversible system, if given enough time, the entropy must get to its maximum value and the information must get to its minimum value.Under the restriction of uncertainty law, we can find deeper layer structure in which we could calculate the information amounts.In the deepest layer of structure, when the system information gets to zero, the micro system’s single particle must have the fewest information particles among the elementary particles.Form the theory of relativity, we get: dv >0 v stands for the speed of elementary particles in the special in-reversible sole system.It shows that the direction of entropy adding up is to make the particle’s ultimate elementary particles come to the speed of light.The particle at last will break up into the ultimate elementary particle whose rest mass is zero.That’s to say in a completely sole and no restriction physics system, entropy increase principle makes the system’s total rest mass zero.Form the theory of relativity, a rest mass which is not a zero matter couldn’t be accelerated to light speed.But we think it can be broken up into light speed photon.So photon’s rest mass is zero and its information is 1 bit particle.It is the ultimate elementary particle of matter.Namely the fastest speed is photon which is also the fewest information particle.Photon is the limit while dividing the elementary.On the other hand, we can use photon to form a coordinate in order to survey a sole physics system.Based on theory of relativity, we will find those which form the physics system are all light speed particles, Viz.photon.Generally speaking, people won’t build a photon coordinate to survey a sole physics system, because it is the extreme condition.But if a common physics law could not apply to an extreme condition, what is the common?

Either using information decrease principle, or entropy increase principle or photon coordinate principle to survey matter, we can draw a conclusion that photon is ultimate elementary particle of matter.7.Information and rest mass

Suppose there are two photons A, B.They are moving in light speed.Their moving mass(total kinetic energy)are mA, mb.Since A,B are owning moving mass, they also have some magnetic characteristic.A and B combine into an elementary particle------a particle which has “strong character”, when photons interact with each other, and produce position energy.Now, we suppose the position energy of A, B are VA , VB*.The total moving energies are mA*, mB*.Then the total energy of A and B is: VA*+ mA*,VB*+ mB* Considering A, B as a general M, then M’s total rest mass m is: M=VA*+ mA*+VB*+ mB*

The rest mass(Viz.proper mass)which consists of the ultimate elementary particles is the total value of position energy produced in the circumstance that the matter’s inner particles interact with each other and total moving energy produced in the circumstance that matter’s inner particle are moving towards each other..In a completely sole and no restriction physics system, following the information decrease principle, with the time going, its ultimate information is 0 bit.We can say that it has no information.At that time, the total rest mass in the whole physics system is also zero.When a physics system owns rest mass, it proves that the inner interaction between photons and particles.So it produces information and vice versa.If the physics system exists nformation(>1 bit), it shows that it owns rest mass.The matter’s information and rest mass are produced by the interactions between photons and particles.If an electron owns information(2 bit), it also owns mass.But by now, we couldn’t come to a conclusion that how much information there is decide how much rest mass there is.What we need is a further study.Photon form matter by a certain way.By the interaction between the photons(or by the effect of power)or by transformation it will form a rest mass particle.At the same time, it will produce position energy and then produce new information and the next produce rest mass.Perhaps we can no longer survey a certain photon of the matter inner.Electron and anti electron can die into a pair of photon.Similarly, several photons could change into an electron.8.The micro information in the wholeuniverse

Firstly, let’s consider the universe as an endless “straight line” model.In order to stress the uncertainty principle, we must divide the one dimension line into line segments.Each length of the line segments stands for the position of the particle and its possible accuracy.If we can confirm the numbers of the particles in each segment, then, about the “straight line” universe, we can use limitless sequence of the particles to express the universe which is formed by “occupation numbers” and open at both ends.The micro information is defined as: it helps us to distinguish two same statistics(macro)character occupation number sequences.Now we try to prove the two sequences are same.We will chose a subsidiary sequence from a occupation number sequence.In a limitless sequence, any length-limited subsidiary sequence will repeat to appear endless times.According the large numbers law after finite times of attempt, we could find out some possessing same characteristic occupation subsidiary sequence.Moreover, despite the length of the chosen subsidiary, so long as the length is finite, we can find that kind of sequences.We extend the above proof to the three-dimension endless universe.So long as it meets the condition that the strong universe principle and the part universe structure are limit, the whole universe character is all statistics(macro)and its micro information does not exist at all.9.The physics character and physics constant of photon affect the universe’s physics law and physics constant

Photon has the character of quantization.Its energy is: he is the Plank constant, v is frequence.Due to the quantization of photon, we think photon can be compounded and broken down.Nevertheless, if its rest mass is zero, it is a photon.For separate particles, they all have the same

physics characteristic.Only in different fields, they show different physics characteristics.Photon owns the characteristics of quanta and electromagnetic.Light speed is its physics constant.The universe consists of photons.So the photon’s physics characteristic and constant affect the universe’s physics law and constant.If the whole universe consists of many small universes, the photon’s physics characteristic and constant in each small universe affect the physics law and constant of this small universe.No matter what circumstance it is, anything happening in the universe seems that its evolution is based on the science laws.All these are affected by photon’s physics characteristic and constant.It is the direction for people of modern physics to study photon’s physics characteristic and constant.I believe that in the future people will know more about photon’s nature and will know more about the matter’s structure.

物流企业绩效评价

摘要:随着实践的发展与学术、媒体的关注和刺激, 物流企业绩效评价系统得到了很好的发展,而基于经济增加值和平衡计分卡(BSC)方法的物流企业绩效评价就此产生。该系统通过相关的测试和线性回归被给予了实证,就长远的眼光而言,经济增值是这个系统最重要的目的。为了得到高的经济效益,这四个方面包括财务、顾客、内部业务流程和学习和成长都将有巨大意义。经济附加值在企业的战略目标和企业价值的相关性上占据绝对的重要地位。在研究企业绩效的线性回归数据中有经济附加值、运行费用、审计报告和员工的内部控制的教育比等数据,他们被用来代表了前面四个方面。其中,财务和企业内部业务流程有量化的系数与理论分析一致。

关键词:绩效评估、物流、经济附加值、平衡计分卡(BSC)

1绪论

随着物流行业的快速发展,物流企业不断的成长和壮大。对于股东来说,一个问题迫切需要解决的问题产生了,即如何对其物流企业进行有效而科学的绩效评价。虽然这个行业具有很大的利润空间,里面有巨大的财富,但是该物流企业经济附加值到底有多大,而如何又能创造出来,作为股东又能获得多少报酬这些都是令人棘手的问题。传统的企业绩效评价以企业财务报表作为分析的基础,在一定程度上反映了企业为股东创造财富的能力和企业生存、发展的能力,但是人们只使用财务数据来支持他们的判断从而就缺乏注意到其他措施,特别是忽视股权成本由股东的投资。在本文中,我们基于平衡计分卡(BSC)建造一个评价指标系统,并围绕EVA作为物流企业绩效评价的指标体系,把经济增值作为一种主要的目标来对物流企业进行绩效评价,并衡量企业的股东获得的真正的财富。然后,本文提供实例证明这个系统的有效性。本文是组织结构如下:第二章相关的理论知识;第三部分建立评价体系根据通过EVA建立指标体系和介绍使用的平衡计分卡方法;四章和第五章对上面介绍的绩效评价方法给予实证;第六部分总结结论。文献回顾

2.1物流绩效评价

物流绩效评价在物流管理中是一个非常重要的问题。科学而准确的评价的结果可以让人们知道他们昨天的工作收获了什么,明天又将要做些什么。

许多外国的日报都聚焦在这三个方面1)介绍应具有的特性,个性 2)该方法需要涉及到的员工3)该企业要选择的方法步骤。而一个建立水平轴的反映国际物流组织所规定的服务质量和性能和垂直轴代表特定服务对客户的重要性的矩阵式相当困难的。

指定物流绩效指标分成三个广阔的领域,包括有形成分、实施途径和信息操作。近年来,人们越来越重视企业的独特的环境行为或公司的策略。有些论文试图为厂商解决如何面对日益变化的市场的问题,这些论文可以动态地解决这一问题的绩效衡量选择,却不是依靠一个静态群的措施。

在中国,物流企业绩效评价研究的主要内容有:1)选择的措施;(2)评价的方法;3)绩效评价体系。一个正确的绩效评价系统通常包含许多个部分。其中,王,杨两个人研究的内容,他们在乎费用、效率、风险、客户管理,而魏强调物流企业的竞争和发展能力。在这些 系统中,最常用的措施都是相关的,比如收入、成本、供应、订单交付延迟时间,指令反馈的精度等。支持以上的理论分析且已应用于物流企业的方法有很多,比如模糊分类方法,主成分分析方法,利用数据包络分析方法等。尽管这些方法都已经有一些高质量的研究成果,但是它们却很少关注公司的策略问题。

2.2平衡计分卡方法

平衡计分卡方法是由罗伯特·卡普兰和大卫·诺顿提出并形成的。它是一种将战略非财务指标添加到传统的给管理者看的财务指标,同时要求均衡的组织中的表现的框架结构的绩效评价方法。经过多年的发展,它成长成为一种全战略规划和管理的绩效评价方法,该方法包括四个方面:财务、客户、内部业务流程、学习和成长。见表一:

在卡普兰和诺顿建立平衡计分卡以后,有些文章开始逐渐将平衡计分卡在应用在物流绩效评价之中。布鲁尔和斯潘通过对先前的平衡积分卡的修改,进而推出一套可用于供应供应链绩效评价的BSC,他们建立的框架包括供应链管理(SCM)的目标、最终客户利益、财务收益、SCM提高;根据平衡计分卡模型,刘和王给出了一个3 + 1的模型,这其中的物流绩效评估包括财务、客户、内部操作和学习四个方面;在孙的导师的论文中,他将平衡积分卡方法与网络程序分析(ANP)相结合来对企业进行绩效评价,该方法以物流企业发展战略作为评价标准,并建立了网络程序分析模型(ANP),由此可以量化绩效评价的影响和便于定量矩阵的反馈。

这些文章都试图添加战略信息并将其转化为物流绩效评估的部分,从而使评价结果对物流企业来说更合理的、更有用。但是平衡计分卡模型在物流企业绩效评价上的应用物流才只是个开始,远非十全十美。再者,很少的研究报告能告诉我们包括股东企业为自己创造的真正的价值。

2.3 经济附加值(EVA)

股东对企业的投资,然而传统意义上的利润不可能告诉我们分与多少股东与其投资相符的红利,继而股东权益得不到强制性保证。投资的机会成本解释了为什么股东选择投资A公司而不是B公司的原因,然而没有效益的投资,谁还会继续。因此忽视利润的分配会导致重大决策失误。

EVA作为商标是由其开发者,斯特恩·斯图尔特和其公司在20世纪80年代注册的。EVA具有很大的吸引力的优势是因为EVA与传统的利润相比较,EVA的计算措施以考虑股本的机会成本为主。以这个方式而言,股东投资就等同于作为贷款的债权人。已经有实证研究支持这个增量,EVA信息内容的价值相关性要高于其他的一些行业的措施。在这同时,EVA有助于制定有效的激励管理,从这个角度来说,EVA的应用对反映出准确的财务绩效从而解决股东和管理的代理问题做出了重大贡献。

尽管EVA的应用受到如此多的赞扬,但是它却还没有来得及在物流行业广泛应用。EVA未能得到物流行业应用的主要原因是因为物流企业有着其自身的特殊性和特征。在本文中,我们设法把EVA和平衡计分卡模型结合在一起建立一个物流企业绩效评价系统。

3基于EVA和BSC的绩效评价系统

战略是企业发展和成功至关重要的因素,其中企业中最盛行的一个策略是公司价值的最大化。策略导向BSC,价值强调EVA,两者的结合可以让企业的绩效评价对齐企业的战略。3.1根据斯坦·斯图尔特定义,EVA一般相当于一个真正的经济效益评估,该评估纠正并调整了正确会计编号。这个基本关系式为:

在(1)中,NOPAT代表网上营业利润税后、IC卡代表公司资本总额联合会代表加权平均资本成本(包括资本投资股东和债权人)。

考虑到高的离职率和现金流的物流,我们做出对(1)做出调整,得到方程(2),如下:

其中:NCFO代表净现金流量从操作、收益;在权责发生制下,ATInt税后利润;TA代表总资产(包括债务和股权);AcctAdj特殊调整的项目,包括商誉、津贴作为坏帐等。3.2战略图

除了EVA,BSC还需要其他更多的指标去联系其框架结构的目标,以及物流企业的特点。我们需要从很多的案例中分析出三者之间的关系,然后再做合理的决策。而BSC提供了一个很好的工具来完成这一过程,这个工具名为战略图,下面给出了一个物流企业的战略图。

认识到战略目的作为战略图的首要任务是很重要的,因为战略目的代表和指导整个发现并建立企业战略的过程。EVA反映了一个物流企业中,股东价值创造的真实的增量,因此它是从财务角度来看的最主要的指标,同时它又是由成本和收入的增长两个关键项目支持的,在财务角度下,我们能够了解需要做出哪些工作来实现EVA。物流企业必须实现客户满意度和保证新客户的产生,这需要高的营业额和较短的交货时间。学习和成长伴随着人类、信息和组织资本。这是最低的观点,然而它却不能被忽视。物流企业的无形资产是最强大的和可持续的满足股东要求的方式。箭头的效果是由低到高的角度,反映了“拉”的联系,这个从低到高的改进需要很长一段时间,但是它将从根本上大幅度的改变公司并给公司一个光明的前途。

3.3方法的选择和EVA的指导作用

在选取具体方法进行绩效评价之前,战略图为我们提供了一种语言来描述的策略,战略图还为物流企业给出了一个走向成功的合理的道路。当利益相关者对物流公司的包括管理、股东、银行家、潜力投资者等方式进行绩效评价的时候,他们想要清晰并且容易的工作。根据卡普兰和诺顿,太多的方法让用户感到困惑,还增加了运营成本。所以按照战略地图的关键词,我们可以列出物流企业绩效评价方法的名单,如表2。他们并不适合所有的公司,但是可以针对某些典型的物流企业。

在这些绩效评估方法中,EVA代表最终的结果和领导前沿,主要是因为它的经济意义。根据在战略地图对这些运行过程的描述,作为一个高效、创造价值的企业将把较高效用的EVA作为其财务评价的结果。

4假设发展

尽管我们基于EVA和BSC对物流企业绩效评价的方法进行了描述,同时简述了EVA 与其他方法的的关系和不同点,但是EVA就真的满足企业长期发展战略的目标么?EVA就真的能在BSC系统的传统绩效评价方法中占据主导地位?

所有的相关信息可以根据市场效率的假设反映在股票市场,上市公司价值几乎跟股票价格是一样的,物流企业也不能例外,虽然中国的股票不可能有市场效率高,但是从1997年的实证表明它已经开始弱化。再者,股票市场的迅速发展,所以对于物流企业而言,市场本身和波动股票价格将会更加重要。企业价值最大化的战略目标将被大众在一般在长期的目标下等同于市场回报最大化。接着,让我们假设1:H1)EVA相比传统的净收益回报,与市场回报具有显著的关系。

作为绩效评价体系的最终结果,EVA应该和其他在BSC四部分有效的措施有重要的关联度。因此我们得到假设2:H2)EVA和其他绩效评价措施相关。

5数据和经验的结果

在绩效评价系统中,大多数的措施都是内部的信息,例如加工时间顺序,所以我们不能让我们所需要的所有的数据去完成实证检验。我们对应一个观点一种手段,包括EVA在内的手段,包括运行成本、第一五客户、收益率、审计的内部控制报告与员工教育的比例。我们找到46家上市物流企业在上海和深圳股票交易作为案例来进行实证检验。因为从2007年起,新的会计准则生效,我们计算的数字调查数据集中于2008年,我们通过删除缺失数据或极端异常的数据得到36个观察结果,这些观察已经被编制到财务信息服务数据库中。

审计报告的内部控制是一种两分法,当内部控制报告可以独立审计,则为1;若不可,其值为0。一个没有独立的外部审计意见内部报告缺乏目的评价,不够支撑一个高品质内部运作过程。为了减少数据上的差异,我们缩小2008年设立的EVA及操作成本总额,这五个描述性统计结果变量见表3:

所有的物流企业有负面的EVA,就是说他们不再继续为股东创造价值,它迫切需要公司向绩效评价体系增加新的EVA。上表中的客户平均收入的比是0.3558,代表前5个客户为物流企业贡献了三分之一的收入。我们发现了大部分公司都没有审计的内部控制报告,显示相对薄弱的内在力量。在员工受教育方面有最低标准偏差,它的均值是0.1838,这放映了物流企业内部人员受教育程度较低。

根据表

4、EVA具有显著的正相关关系与市场回报,支持假设1a。在同一时间,得到一个微不足道的净利润与市场回报,符合假说意向书。也有EVA和净利润之间明显的关系,但相关是消极的,可以看出传统的利润指标的问题。

用线性回归的假设2进行处理,处理结果如表5:

但是审计内部控制报告得到了显著的正面相关性,符合我们的预测;其中前五客户收入与EVA比没有明显关系;教育的比例为显著负系数,虽然得到这些,但是它们不能提供进一步的证据来支持假设2。因为这些结果所采取的措施为客户、学习和成长的观点更多的是根据内部信息,而不是我们所选定的对于财务内部业务流程的内容,所以我们没有合理的代理。我们收集的数据来自于公众物流企业的报告,因为种种原因,可能会有偏见。最后,我们可以做一个结论:假设2部分支持。

6结论

出于学术和实践的重要意义,我们建立一个基于EVA及平衡记分卡的绩效评价体系的为物流企业星星有效的绩效评价。从长远的眼光来研究,将EVA放在作战略地图首位,其他财政,客户,内部业务流程,学习和成长等指标用来辅助。然后我们给每个因素包括EVA定义指标:分别是运营成本、前五客户收益率、内部控制报告和员工受教育的程度。

K相关测试支持EVA和战略目标之间的一致性,另外,我们用线性回归发现运营成本显著的负系数,审计的内部控制报告得到了显著的正面,基本符合了我们的预测,其中前五客户与EVA收入比没有明显关系,受教育教育的比例有显著的负系数关系。

因此,我们觉得基于EVA和平衡计分卡的绩效评价体系是很重要的,它可以帮助物流企业关注战略目标,积极为股东创造价值的增量,并且基于内部信息分析未来的需要。

很多公司企图提高定制当今竞争激烈的全球市场,都利用产品系列和平台基础来开发产品的种类、缩短交易时间和增加收入。一个成功的产品系列的关键是这个产品平台通过添加,删除,或用一个或多个模块用一个或者多个维度的具体目标利基市场来得到产品平台或者扩展产品平台。这项初步工程设计领域在过去十年中迅速成熟,本文提供了一个研究活动发生在这段时间进行基于大批量定制的产品开发平台产品族系列综合评述的设计。用一种产品系列来评估产品平台杠杆策略的技术通常用于审查和度量评估产品平台和产品系列的有效性。特别强调的是优化方法和人工智能技术协助的产品系列设计方法和基于平台的产品开发。基于web的产品平台定制系统仍需要讨论。学术界和工业界的例子就是之前在前文中强调了的产品系列和产品平台的好处。本文讨论的结论是运用潜在的研究领域帮助构建产品系列的制造和设计之间的桥梁。

当今竞争激烈的全球市场重新定义着许多公司做生意的方式。这种新形式的竞争优势是大规模定制,而且正如pine说的“一种新的查看竞争业务的方式,这种不以牺牲效率,有效性和花费的方式进行识别和实现个人客户最主要的需要和需求。”在pine对大规模定制的开创性探索中,他认为“消费者可能已经不再被这个巨大的同质市场聚集在一起,但是个人的需求可能与众不同并且这些需求是可以确定和满足的。”他把越来越多的注意力放在产品的种类和客户来满足市场的饱和度和提高客户满意度的需求:新产品必须不同于市场上现有的产品,并且尽可能的满足客户的需求。作为市场产生的动力,从汽车行业研究的和实证调查制造公司确认的这些结果来看,佩特森和犹梅里补充说明“正如许多公司知道的那样全球化市场的兴起已经从根本上改变了竞争,那就是强制压缩产品的开发时间,努力增加产品的种类。”类似的主题被沃克曼贯穿了这篇文章(1997),他在欧洲为“客户驱动”市场研究行业的反应。

社会的发展、技术的进步、产品的更新、生活节奏的加快等等一系列的社会与物质的因素,使人们在享受物质生活的同时,更加注重产品在“方便”、“舒适”、“可靠”、“价值”、“安全”和“效率”等方面的评价,也就是在产品设计中常提到的人性化设计问题。

所谓人性化产品,就是包含人机工程的的产品,只要是“人”所使用的产品,都应在人机工程上加以考虑,产品的造型与人机工程无疑是结合在一起的。我们可以将它们描述为:以心理为圆心,生理为半径,用以建立人与物(产品)之间和谐关系的方式,最大限度地挖掘人的潜能,综合平衡地使用人的肌能,保护人体健康,从而提高生产率。仅从工业设计这一范畴来看,大至宇航系统、城市规划、建筑设施、自动化工厂、机械设备、交通工具,小至家具、服装、文具以及盆、杯、碗筷之类各种生产与生活所创造的“物”,在设计和制造时都必须把“人的因素”作为一个重要的条件来考虑。若将产品类别区分为专业用品和一般用品的话,专业用品在人机工程上则会有更多的考虑,它比较偏重于生理学的层面;而一般性产品则必须兼顾心理层面的问题,需要更多的符合美学及潮流的设计,也就是应以产品人性化的需求为主。

人机工程学是一门新兴的边缘科学。它起源于欧洲,形成和发展于美国。人机工程学在欧洲称为Ergonomics,这名称最早是由波兰学者雅斯特莱鲍夫斯基提出来的,它是由两个希腊词根组成的。“ergo”的意思是“出力、工作”,“nomics”表示“规律、法则”的意思,因此,Ergonomics的含义也就是“人出力的规律”或“人工作的规律”,也就是说,这门学科是研究人在生产或操作过程中合理地、适度地劳动和用力的规律问题。人机工程学在美国称为“Human Engineering”(人类工程学)或“Human Factor Engineering”(人类因素工程学)。日本称为“人间工学”,或采用欧洲的名称,音译为“Ergonomics”,俄文音译名“Эргнотика”在我国,所用名称也各不相,有“人类工程学”、“人体工程学”、“工效学”、“机器设备利用学”和“人机工程学”等。为便于学科发展,统一名称很有必要,现在大部分人称其为“人机工程学”,简称“人机学”。“人机工程学”的确切定义是,把人—机—环境系统作为研究的基本对象,运用生理学、心理学和其它有关学科知识,根据人和机器的条件和特点,合理分配人和机器承担的操作职能,并使之相互适应,从而为人创造出舒适和安全的工作环境,使工效达到最优的一门综合性学科。

AI EDAM: Artificial Intelligence for Engineering Design, Analysis and Manufacturing

In aneffort to improve customization for today’s highly competitive global mar ketplace, many companies are utilizing product families and platform-based product development to increase variety, shorten lead times, and reduce costs.The key to a successful product family is the product platform from which it is derived either by adding, removing, or substituting one or more modules to the platform or by scaling the platform in one or more dimensions to target specific market niches.This nascent field of engineering design has matured rapidly in the past decade, and this paper provides a comprehensive review of the flurry of research activity that has occurred during that time to facilitate product family design and platform-based product de velopment for mass customization.Techniques for identifying platform leveraging strategies within a product family are reviewed along with metrics for assessing the effectiveness of product plat forms and product families.Special emphasis is placed on optimization approaches and artificial intelligence techniques to assist in the process of product family design and platform based product development.Web-basedsystems for product platform customization are also discussed.Examples from both industry and a cademia are presented throughout the paper to highlight the benefits of product families and product platforms.The paper concludes with a discussion of potential areas of research to help bridge the gap between planning and managing families of products and designing and manufacturing them.Today’s h igh ly competitive global mark etplace is redefining the way many companies do business.The new form ofcompetitive advantage is mass customization, and is, as Pine~1993a, p.xiii!says, ―a new way of viewing business competition , one that makes the identification and fulfillment of the wants and needs of individual cu stomers paramount without sacrificing efficiency, effectiveness, and low costs.‖In his seminal text on mass customization, Pine ~1993a,p.6!argues that ―customers can no longer be lumped together in a huge homo geneous market, but are individuals whose individual wants and needs can be ascertained and fulfilled.‖ He attributes the increasing attention on product variety and customer demand to the saturation of the market and the need to improve customer satisfaction: newproducts must be different from what is already in th e market and must meet cu stomer needs more comp letely.Sand-erson and Uzu meri ~1997, p.3!add that ―the emergence of global markets has fundamentally altered competition as many firms have known it‖ with the resulting market dynamics ―forcing the compression of product development times and expansion of product variety.‖ Findings from studies of the automotive industry ~Womacketal., 1990;MacDuffieetal., 1996;Alford et al., 2000!and empirical su rveys of manufacturing firms ~Chinnaiah et al., 1998;Duray et al.,2000!confirm these trends.Similar themes pervade th e tex t by Wortmann et al.~1997!, who examine industry’s response in Europe to the ―customer-driven‖ market.The social development and technological progress, product updates, rhythm of life pace, and so on a series of social and physical factors, so that people in the enjoyment of material life at the same time, pay more attention to products in the “convenience”, “comfortable”, “reliable”, “value”, “security” and “efficiency evaluation, is often mentioned in the product design, personalized design.山东交通学院毕业设计(论文)

The so-called user-friendly products that includes the man-machine engineering products, as long as it is ”person“ used in products should be considered in the man-machine engineering, product design and ergonomics is undoubtedly together.We can be described as: Center for psychological, physiological radius in order to build a harmonious relationship between people and things(products), maximum to tap potential, comprehensive balanced use of muscle, protection of human health, so as to improve the productivity.Only from the category of industrial design, to aerospace systems, urban planning, construction, automatic chemical plant, machinery and equipment, transport, small furniture, clothing, stationery and flower pots, cups, bowls and chopsticks, such as production and life to create the ”objects“, in the design and manufacture must take the ”human factor“ as an important condition to consider.If the products of distinguished professional supplies and general supplies and professional activities in the man-machine engineering will have more consideration, it is more emphasis on in physiology level;and general products must balance the psychological problems, need to be more in line with the aesthetics and the trend of the design, that is, should be to the needs of the product humanization.Ergonomics is a rising edge science.It originated in Europe, formed and developed in the United States..Ergonomics in Europe known as ergonomics, the name of the first is by Poland scholar Ya J Tele Bo J J Kiti, it is composed of two Greek roots.The meaning of ”ergo“ is ”output,“ and nomics said the meaning of ”law, rule.Therefore, ergonomics meaning is“ people contribute to the rules ”or“ working rules ”.That is to say, the subject is the research in the production or operation of reasonable, moderate labor and force of law of.Ergonomics in the United States known as “Engineering Human”(Human Engineering)or “Factor Engineering Human”(Human Factor Engineering).Japan, known as the “human engineering”, or the European name, transliterated as “Ergonomics”, Russian transliteration names “middle, in this paper the author, with large K” in our country, with the name of a also varied, with “human engineering”, “human engineering”, “Ergonomics”, “equipment using learning” and “Ergonomics”.For the development of subject, it is necessary to unify the name
