热能与动力工程专业英语

第一篇：热能与动力工程专业英语

强度量：intensive properties do not depend on mass（e,g,p,ρ,ν=1/ρ,u and h）,extensive properties depend on the total mass of the system（e,g,V,M,U,and H）.Uppercase letters are usually used for extensive properties.准平衡：equilibrium：states of a system are most conveniently described when the system is in equilibrium, i.e.it is in steady-state.Often we will consider process thatchange “slowly”-termed quasi-equilibrium or quasi-static process.A process is quasi-equilibrium if the time rate of change of the process is slow relative to the time it takes for the system to reach thermodynamic equilibrium.It is necessary that a system be quasi-equilibrium before applying many of the thermodynamics relations to that system.热力学第一二定律：In simplest terms,the law of thermodynamics dictate the specific for the movement of heat andwork.Basically,the First Law of Thermodynamic is a statement of the conservation of energy-the Second Law is a statement about the direction of that conservation-and the Tired Law is a statement about reaching absolute Zero.The first law of thermodynamic is a statement of the principle of conservation of energy.It can also be considered as defining a property,the internal energy.The Second law of Thermodynamic states that in all energy exchanges,if no energy enters or leaves the system,the potential energy of the state will always be less than that of the initial states.This is also commonly referred to as entropy.举例说明热力学定律应用：a cup of hot coffee left on a table eventually cools,but a cup of cool coffee in the same room never gets hot by itself.The high-temperature energy of the coffee is degraded(transformed into a less useful form at a lower temperature)once it is transferred to the surrounding air.An ordinary house is,in some respects,an exhibition hall filled with womders of thermodynamics.Many ordinary household utensils and applicances are designed,in whole or in part,by using the principles of thermodynamics.Some examples include the electric or gas range,the heating and air-condition systems,the refrigerator,the humidifier,the pressure cooker,the water heater,the iron,and even the computer,and the TV.On a large scale,thermodynamics plays a major part in the design and analysis of automotive engines,rockets,jet engine,and conventional or nuclear power plans,solar collectors,and the design of vehicle form ordinary cars to airplanes.绝热系统：isolated systems：not exchangeing heat,matter or work with their environment.开口系统：exchanging energy(heat and work)and matter with their environment.闭口系统：exchangeing energy(heat and work)but not matter with their environment.孤立系统：rigid boundary :not allowing exchange of work.辐射换热:The mechanism in this case is electromagnetic radiation.We shall limit our discussion to electromagnetic radiation which is propagated as a result of a temperature difference;this is called thermal radiation.对流传热:when a fluid at rest or in motion is in contact with a surface at a temperature different from the plate ,energy flows in the direction of the lower temperature as required by the principle of thermodynamics.we say that heat is convected away ,and we call the process convection heat transfer.对流传热的方式:There are two convection modes :forced convection and natural convection.If a heated plate were exposed to ambient room air without an external source of motion ,a movement of the air would be experienced as a result of the density gradients near the plate.We call this natural ,or free ,convection as opposed to forced convection ,which is experienced in the case of the fan blowing air over a plate.传热学:Heat transfer is the science that seeks to predict the energy transfer that may take place between material bodies as a result of a temperature difference.传热学和热力学的区别:Thermodynamics teaches that this energy transfer is defined as heat.The science of heat transfer seeks not merely to explain how heat energy may be transferred ,but also to predict the rate at which the exchange will take place under certain specified conditions.The fact that a heat-transfer rate is the desired objective of an analysis points out the difference between heat transfer and thermodynamics.Thermodynamics deals with systems in equilibrium;it may be used to predict the amount of energy required to change a system from one equilibrium state to another;it may not be used to predict how fast a change will take place since the system is not in equilibrium during the process.Heat transfer supplements the first and second principles of thermodynamics by providing additional experimental rules which may be used to establish energy-transfer rates.As in the science of thermodynamics ,the experimental rules used as a basis of the subject of heat transfer are rather simple and easily expanded to encompass a variety of practical situations.影响辐射传热的因素：To take account of the “gray” nature of such surface we introduce another factor into

Equation ,called the emissive ε:which relates the radiation of the “gray”surface to that of an ideal black surface.We must take into account the fact that not all the radiation leaving one surface will reach the other surface since electromagnic radiation travels in straight lines and some will be lost to the surroundings.热能与动力工程thermal energy and power engineering 能量转化energy-transfer 比例常数proportionality constant 比例系数proportionality factor 活性中心active center 对流传热convection heat transfer 电磁辐射electromagnetic radiation 角系数view factor 准静态过程quasi-static process 准平衡quasi-equilibrium 静态平衡static equilibrium 强度参数intensive property 广延参数extensive property 燃烧机理combustion mechanism平均分子运动average molecular motion 热反应堆thermal reactor 热力学性质 thermodynamic property 摩尔热容molar heat capacity 动能kinetic energy 压缩因子compressibility factor 温度传感器temperature sensor 测量电路measurement circuit 电压输出voltage output 静电荷electrostatic charge 励磁电源excitation power 内能internal energy 能量原理energy principle 能量平衡energy balance 能量守恒conservation of energy 剪切应力shear force/stress 角速度angular velocity 速度梯度velocity gradient 温度梯度temperature gradient 一维one-dimensional 机械能mechanical energy 内能internal energy 动能kinetic energy 势能potential energy 凝固/硬化take a set 流体动力学fluid dynamic hydrodynamics 蒸汽发生系统steam generating system 辅助设备auxiliary equipment 空煤比the air-coal ratio 质量作用定律the law of mass action 阿伦尼乌斯定律arrhennius law 活化分子active molecule 活化分子碎片active molecule fragments 活化能activation energy

浅谈热能与动力工程专业的就业前景

摘要人类发展至今，已经经过了柴草时期、煤炭时期、石油时期，并已进入新能源时期，随着科技的发展，越来越多的能源得到了开发和利用，能源和人类的生活也越来越紧密联系，本文主要探讨能源发展的历史与前景，以及热能与动力工程专业毕业生的就业展望。

关键词能源 热能与动力工程专业 就业

正文

马克思曾经说过“世界是物质的，物质是运动的”，我们可以由此看到，世界上一切客观事物的存在，都离不开能源。从古至今，能源一直在人们的生产生活中扮演着重要的角色。18世纪以前的人们知道用火取暖，加热食物，驱赶野兽，从而得以进化，那时，对能源的利用还比较低等，需求也不是特别大，并没有动力推动对能源的开发和利用，我们称之为“柴草时期”。接着，人们进入煤炭时期，对煤炭的开采始于13世纪，而大规模开采并使其成为世界的主要能源则是18世纪中叶的事了。1769年，瓦特发明蒸汽机，煤炭作为蒸汽机的动力之源而受到关注。并随之产生了第一次产业革命，第一次产业革命期间，冶金工业、机械工业、交通运输业、化学工业等行业的大幅发展，使煤炭的需求量与日俱增，直至20世纪40年代末，在世界能源消费中煤炭仍占首位。第二次世界大战之后，在美国、中东、北非等地区相继发现了大型油田及伴生的天然气资源，由于每吨原油产生的热量是煤的两倍。并且石油炼制得到的汽油、柴油等是汽车、飞机使用的内燃机燃料。世界各国纷纷投资石油的勘探和炼制，新技术和新工艺不断涌现，石油产品的成本大幅度降低，发达国家的石油消费量猛增。到20世纪60年代初期，世界能源消耗中，石油和天然气的消耗比例开始超过煤炭而居首位。而今，进入21世纪已有8年，我们又进入了一个新的能源时代：新能源时代。核能、太阳能、风能、地热能、潮汐能、氢能、生物能等大量新能源得到了开发与利用。有些新能源也已经有实验室走进了人们的家中。与此同时，由于石油等矿物能源产量的制约和某些政治上的因素，传统能源已显示出疲态，人们对能源的关注度也提升到了一个较高的高度。

我有幸考入北京科技大学机械工程学院，从而得到了选择热能与动力工程专业的机会。北京科技大学热能工程系始于1958年的冶金系冶金炉专业，有着悠久的历史。拥有热能工程、工程热物理、制冷及低温工程、流体机械与工程、动力机械与工程、化工过程机械6个主要学科，博士一级学科点一个、二级学科点六个、博士后流动站一个以及国家与北京市重点学科，可以授予从工学学士到博士的一系列学位。身为一名首都大学生，我深刻地认识到了自己的时代使命。从国家角度，中国依然没有统一，存在着些许历史遗留问题，需要许许多多的我们付出努力使之强大起来。从个人角度，我们毫无疑问应该追求更高的精神世界与更好的物质条件，而这一切需要稳定的工作和收入来保障。2007年，全国本科毕业生达到480万，岗位缺口1200万，这一数字已经逐年增增长，并将在一定时期内持续增长下去。在2007年的昆明市的公务员报名中，甚至出现了302人抢一个职位的景象。我们可以看到，目前就业压力日益严重，如何找到符合自己兴趣，适应就业趋势的专业已经成了广大准毕业生的当务之急。

记得2002年电子商务兴起的时候，有人预言机械将会成为夕阳产业，因为轻工业、电子商务的兴起与发展势必会降低重工业在国家经济中所占有的比例。时至今日，这种论断不仅没有实现，反而恰恰相反，国内的机械生产水平得到了空前的提高，对专业对口毕业生的需求也有增无减，可以预见的是，本专业的毕业生会在节能、制冷、动力、环保领域的设计开发、制造生产、运行管理、科研教学等方面大有作为。

北京科技大学机械工程学院热能工程系教授王立说过：能源无所不是、无处不在！毫无疑问，人类想要生存下去，能源是一个必须解决的问题，热能与动力工程专业恰恰满足了这一需求。
