第三篇:专业自动化英语句子翻译
专业英语翻译
1.In the case of a resistor(电阻), the voltage-current relationship is given by Ohm’s law, which states that the voltage across the resistor is equal to the current through the resistor multiplied by the value of the resistance.就电阻而言,电压—电流的关系由欧姆定律决定,欧姆定律指出:电阻两端的电压等于电阻上流过的电流乘以电阻值。
2.the fundamental law that is applied in(被应用)this method is Kirchhoff’s first law, which states that the algebraic sum of the voltages(电压的代数和)around a closed loop is 0,or ,in any closed loop, the sum of the voltage rises must equal the sum of the voltage drops.这里用到的基本定理是基尔霍夫第一定理,这一定理指出:闭合回路电压代数和为0,在任何闭合回路中,电压增加总量与电压下降的总量相同。
3.Mesh analysis consists of assuming that currents—termed loop(回路)currents— flow in each loop of a network, algebraically summing(代数和)the voltage drops around each loop, and setting each sum equal to 0.网孔分析指的是:假设有一个电流—即所谓的回路电流—流过电路中的每一个回路,求每一个回路电压降的代数和,并令其为零。
4.One problem with electronic devices corresponding to the generalized amplifiers is that the gains ,Au or Ai, depend upon internal properties of the two-port system.对应于像广义放大器这样的电子器件存在一个问题就是他们的增益Au or Ai取决于双端口系统的内部特征。
5.The operational amplifier, or Op-Amp, is designed to minimize this dependence and to maximize the ease of design.运算放大器被设计的使它尽可能的减少对其内部参数的依赖性,最大程度地简化设计工作。
6.The transistor amplifiers, which are the building blocks from which Op-Amp integrated circuits are constructed , will be discussed.作为构建运算放大器集成电路的基本模块,晶体管放电器,将会被讨论。
7.Integrated circuit technology allows construction of many amplifier circuits on a single composite “chip” of semiconductor material(半导体材料).集成电路技术使得在非常小的一块半导体材料的复合“芯片”上可以安装许多放大器电路。
8.One key to the success of an operational amplifier is the “cascading”(串联)of a number of transistor amplifiers to create a very large total gain.运算放大器的成功的关键是串联许多个晶体管放电器以产生非常大的总增益。
9.A second important factor is that these circuit can be built in such a way that the current flow into each of the inputs is very small.第二个重要因素是这些回路是按照流入的每一个输入电流都很小的原则来设计制作的。
10.This is one of the features of Op-Amp design –the action of the circuit on signals depends only upon the external element which can be easily varied by the designer and which do not depend upon the detailed character of the Op-Amp itself.这是运算放大器设计的重要特征之一—在信号作用下,电路的动作仅取决于能够容易被设计者改变的外部元件,而不取决于运算放大器本身的微观特性。
11.Note that if A=100000 and(R1 +R2)/R1=10, the prize we have paid for this advantage is that we have used a device with a voltage gain of 100000 to produce an amplifier with a gain of 10.注意,如果A=100000 而(R1 +R2)/R1=10,那么为此优点而付出的代价是用一个具有100000倍电压增益的器件产生一个具有10倍增益的放大器。
12.we shall now briefly discuss the relevance of such terminology(术语),and in so doing we shall bring out the special aptness of the designation “true” and “false” to identify the possible values of a variable.现在我们将简要讨论一下这些术语之间的联系,并在此过程中我们应该阐明用特殊标示“真”和“假”来识别一个可能值的变量。
13.Finally let us connect the inputs to the devices on the chairs of pilots A and B and arrange that an alarm bell, connected to the output Z, respond when the output is V2(“true”)and not otherwise.最后,让我们把输入和 飞行员A和B座位下的装置联接起来,并安装一个与输入Z相连的警铃,当输出是V2(”真“)时响应,否则不响应。
14.Just as other algebras deal with variable which have a numerical significance, Boolean algebra deal with proposition and is an effective tool for analyzing the relationships between propositions which allow only two mutually exclusive alternative.和其他处理有数字意义变量的代数一样,布尔代数处理的是命题,而且布尔代数对于分析仅有两个互反变量的命题之间的关系是一种有效的工具。
15.Similarly, if an effective is to be produced by a change in a logical variable , it is preferred that the logical variable so involved(有关的逻辑变量)be defined in such manner that the effect is achieved when the logical variable goes to logic 1.类似的,如果效果将通过逻辑变量的变化而产生的,那么最理想的是以这样的方式定义有关的逻辑变量,即当逻辑变量转到逻辑1时达到此效果。
16.control systems designed by humans are used to extend their physical capabilities, compensate for their physical limitations, to relieve them of routine or tedious tasks, or to save money.控制系统被人们用来扩展自己的能力,补偿生理上的限制,或把他们从规矩,单调的工作中解脱出来,或者用来节省开支。
17.The analysis phase is concerned with determination of the response of a plantthe controlled object)to commands, disturbances, and changes in the plant parameters.系统分析关注的是命令,扰动和系统参数的变化在被控对象响应中的决定性作用。
18.If the response is unsatisfactory and modification of the plant is unacceptable, a design phase is necessary to select the control elements(the controller)needed to improve the dynamic performance to acceptable levels.如果响应不满足要求且修改的参数不被接受,就需要进行系统设计,来选择使动态性能达到接受要求的控制元件。
19.In those more complex cases where it is not adequate, the classical approach solution may aid in applying the modern approach and may provide a check on the more complete and exact design.在那些更复杂的情况中,经典方法虽不能满足,但解决方法可以对应用现代方法起辅助作用,而且可以对设计进行更完整和准确的检查。
20.Modern control theory has arisen with the advent of high-speed digital computers and can be characterized by the states variable concept(状态变量的概念)with emphasis on matrix algebra and with analysis and design principally in the time domain.现代控制理论是随着高速数字计算机的出现而发展起来的,它以状态变量的概念为特征,重点在于矩阵代数,分析和设计主要是在实域中。
21.Intuitively, a stable system is one that remains at rest(or in equilibrium)unless excited by an external source and returns to rest if all excitation are removed.直观地说,一个稳定的系统是保持稳定的(或平衡),除非受到外部激励,并且如果所有的外部激励去除后回到稳定状态。
22.So, a necessary and sufficient conduction for the system to be stable is that the roots of the characteristic equation have negative real parts.This ensures that the impulse response will decay exponentially with time.所有说,一个系统稳定的充要条件是特征方程有负实根。这确保脉冲响应随时间呈指数衰减。
23.The Routh criterion: All the roots of the characteristic equation have negative real parts if and only if the elements of the first column(列)of the Routh table have the same sign.Otherwise, the number of roots with positive real parts is equal to the number of changes of sign.劳斯判据表明:特征方程的所有根有负实部,当且仅当劳斯表中第一列元素有相同符号。否则,正实部根的数量等于符号改变的数量。

26.For the Intel 8086/87 and Motorola MC68000 microprocessors, a word is 16 bits long, but each memory location has only 8-bit locations and thus two 8-bit locations must be accessed to obtain each data word.对于Intel 8086/87或者Motorola MC68000 微处理器,一个字节的长度为16位,但每一个内存单元只有8位,因此,两个8位单元必须被访问为得到每个数据字节。
27.Instruction stored in memory stored in memory are fetched by the CPU and unless program branches occur ,they are executed In the sequence they appear in memory.存储在存储器中的指令由CPU获取的并且除非程序跳转,它们仍然会按内存中出现的顺序被执行。

2传感器技术在机电技术当中的应用
由于传感器的电磁兼容性能比较强,因此具有较高的数据存储技术可行性,同时还不容易丢失其中的模块参数。智能滤波算法以及A/D转换技术等先进的技术都在传感器当中得到了应用,就算是满量程的时候,传感器仍然可以使稳定的输出码得到保证。传感器的通讯接口属于标准的接口,其能够与计算机进行直接的连接,同时也可以连接标准的工业控制总线,具有十分灵活的使用方式。
2.1在机器人中传感器技术的应用
作为典型的仿生装置,机器人对传感器技术进行了充分的应用。通过将感知到的物理量向电量进行转化,机器人就可以实现信息输出,在这个过程中对机器人传感技术进行了充分的利用,其中包括两方面的内容,也就是外部传感器以及内部传感器。外部传感器需要通过检测外部信息,从而对工作环境进行判别,为机器人提供必要的信息,使之能够对操作对象进行准确的控制。而实施系统的控制是内部传感器的主要功能,其能够对机器人的状态进行有效的检测,保证机器人在工作的过程中能够按照要求来进行。内部传感器可以将具有价值的信息提供给外部传感器,从而能够使机器人对外部的环境产生有效的感知,并且将相应的动作做出。与此同时,在科技生产的过程中,还可以利用对机器人的操作从而能够对反馈的意见进行获取。
2.2在机械制造行业中传感器技术的应用
由于在机械制造行业当中需要实施包括加工精度等在内的动态特性测量,因此要利用传感器针对机械阻抗以及振动等相关部件当中的参数进行测量,从而对其动态特性进行检验。如果需要在线监测与控制超精加工中的零件尺寸的时候,就要利用传感器将相关的信息提供出来。比如利用传感器针对数控车床中车刀的位置进行检测;由于工件的表面精度以及尺寸在很大程度上都会受到刀尖形状的影响,可以采用在车刀上放置的振动传感器对其锋锐的程度进行检验。还可以利用液面传感器针对液压系统中的油量以及车床中的润滑油进行监测。
2.3在环境当中传感技术的应用
传感器网络在环境监测当中通常具有一系列的优点,其中包括无需专人现场维护、可以长期不用对电池进行更换、具有十分简单的布置等。可以利用对节点进行密集的布置,从而对微观的环境因素进行观察。在环境监测领域当中对传感器网络具有非常广泛的应用,其中包括微观观测生物群落、森林火灾报警、观察气象现象、观测海岛鸟类的生活规律等。
2.4在火灾报警当中传感器技术的应用
防灾报警装置是现代建筑必须要具备的,其中最为关键的就是火灾报警系统。在发生火灾的时候一般都会出现有害气体、高温、火光以及烟雾等。如果将传感器运用到火灾报警系统当中,就可以对异常的信号进行转化,使之变成容易进行传送的形式,然后就可以利用消防网络向指挥中心提供火灾地点的报告。
3结语
传感器技术在机电技术当中的应用,有效的将信息系统中的传递问题解决了,并且能够保证非常流畅的信息传递,还能够顺利的进行能量转换。机电系统中的各个部分在传感器技术的作用下能够有效的结合在一起,实现了可靠性以及完整性的提升。因此。我们有理由相信,随着科学技术的不断发展,传感器技术必然会在机电技术当中得到更进一步的应用。
