机电专业英语第2版电子教案Unit2第一篇:机电专业英语第2版电子教案Unit 2Unit 2 Machine Elements I.Lead in Information related to the text Do you know what is referred to as a machine element? Which elements are associated in pairs? Can you give an example? What is the most common machine element? How can the supporting structure be assembled? Why does the individual reliability of machine elements become the basis for estimating the overall life expectancy of a machine? Maybe you have seen and you are much interested in some machine elements, of course also interested in these questions.In this unit, you’ll learn some machine elements and know how they are widely used in industry.Now, let’s study new words and phr ases together.II.Word Study 1.individual [,indi'vidjuəl] adj.个别的n.个人,个体 1)These styles can be adapted to suit individual tastes.这些式样均可改动以适应个人不同的爱好.2)Who was the individual champion? 谁是个人项目的冠军?3)Am I a Business or Individual account? 我采用企业帐户还是个人帐户? 2.disma ntle [dis'mæntl] v.拆除...的设备, 分解1)To dismantle or raze;tear down.拆除,毁坏:拆除,摧毁;拆毁 2)Before mounting, You can not dismantle the plug of port in case the dirty entering.装机前不得将各油口堵塞拆掉,以防脏物进入。
Unit 1 MetalsThe use of metals has always been a key factor in the development of the social systems of man.在人类社会的发展中,金属的应用一直起着关键的因素Of the roughly 100 basic elements of which all matter is composed, about half are classified as metals 构成物质的大约100多种元素中,大约有一半为金属元素。
The distinction between a metal and a nonmetal is not always clear-cut.金属和非金属之间的区别并不是很明显The most basic definition centers around the type of bonding existing between the atoms of the element, and around the characteristics of certain of the electrons associated with these atoms. 最基本的定义集中在元素原子间存在的连接形式和与这些原子相关联的电子的某些特性.In a more practical way, however, a metal can be defined as an element which has a particular package of properties.然而,在实际应用中,金属可以定义为具有某些特性集合的某种元素。
Metals are crystalline(晶体的)when in the solid state and, with few exceptions (e.g. mercury), are solid atambient temperatures(常温下). 除少数金属外如水银,金属在常温下是固态的They are good conductors of heat and electricity and are opaque(nonopaque)to light。

由于业务增长和开拓在很大程度上有赖于业务关系的建立,因此,适当得体的贸易信函是至关重要的。
欲与对方通过信函建立业务联系时,一定要告诉对方你是如何得知对方信息以及你们的主要业务领域,然后陈述目的和需求,最后表达你们想与对方在未来建立合作的诚挚愿望。
一、Place a “T” before sentences that are true and an “F” before those that are false ( T )1、A worm gear is sometimes used in machines, it has low friction that can save considerable power.蜗轮有时用在机器上,具有低的摩擦,可节省相当大的力。
( T )2、In a cam mechanism, when the cam turns through one motion cycle, the follower executes a series of event consisting of rises, dwells and returns.在一个凸轮机构中,当凸轮转过一个运动周期时,从动件执行一系列由上升、停留和返回的动作。
( T )3、Integrated circuit is built on a semiconductor substrate, usually one of multi-crystal silicon.集成电路是建立在一个半导体衬底,通常是多晶硅。
( T )4、Krichhoff’s voltage law states that the sum of the potential drops around a loop in a circuit must be zero.Krichhoff电压定律指出,在电路中的回路的电位下降的总和必须为零。
( F )5、Electrons and protons are said to have the same positive charges.电子和质子具有相反的电荷。
( T )6、If a sinusoidally varying voltage source is connected across the capacitor, it can be shown that the voltage across the capacitor lags the current by in phase, meaning that the voltage peaks occur 1/4 of an oscillation period later in time relative to the current peaks.如果一个以正弦波形式随时间正负变化的电压源加在电容上,将会使电容电压在相位上滞后于电流,即该电压的峰值会比电流的峰值晚出现四分之一个周期的时间。
