The disadvantages of pulleys, in contrast to machines that use rigid objects to transfer force,are slipping and stretching.2.齿轮是通过相继啮合齿方式传递运动机械元件。
Gears are machine elements that transmit motion by means of successively engaging teeth.3.简单的并联电路，所有部件连接电相同的两组之间的共同点,创建电子从电池的一端流到其他多个路径。
With simple parallel circuits, all components are connected between the same two sets of electrically common points，creating multiple paths for electrons to flow from one end of the battery to the other.4.在其最简单的形式中，振动可以被认为是振荡或物体围绕平衡位置的重复运动。
In its simplest form, vibration can be considered to be the oscillation or repetitive motion of an object around an equilibrium position.三、英译汉（50分，5道）plex machines are made up of moving parts such as inclined planes,levers,gears,cams,cranks, Springs,belts,and wheels.复杂的机器是由运动部件组成，如倾斜面，杠杆，齿轮，凸轮，曲柄，弹簧，皮带和轮子。
2.An inclined plane decreases the force required to raise an object a given height by increasing the distance over which a force must be applied.倾斜面通过增加在其上的力必须施加的距离，来减少提高物体的给定高度时所需的力。
3.Both the inclined plane and levers could lower the force required for a task at the price of having to apply that force over a longer distance.倾斜面和杠杠都可以应用更长距离上的力来降低完成一个任务所需的力。
4.Pulleys can be used to simply change the direction of an applied force or to provide a force/distance tradeoff in addition to a directional change.滑轮可被用于简单地改变作用力的方向，或除了改变方向外还提供一个力和距离的权衡。
5.There are a number of different standard gear types. Examples include spur gears, change gears, cluster gears, helical gears, herringbone gears, straight bevel or spiral bevel gears, worm gears, and so on and so forth.有许多不同的标准齿轮的类型。
实例包括正齿轮，变速齿轮，簇齿轮组，斜齿轮，人字齿轮，直齿锥或螺旋锥齿轮，蜗轮，依此类推等等。
6.A cam mechanism usually consists of two moving elements, the cam and the follower. 一凸轮机构，通常包括两个运动元件，该凸轮和从动件。
7.We can classify cam mechanisms by the modes of input/output motion, the configuration and arrangement of the follower, and the shape of the cam.我们可以通过输入/输出运动，配置和从动的布置，和凸轮的形状的模式分类凸轮机构。
8.In a cam mechanism, when the cam turns through one motion cycle, the follower executes a series of events 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。
9.Electrons and protons are said to have opposite electric charges.电子和质子具有相反的电荷。
10.Voltage can be generated by means other than rubbing certain types of materials against each other. Chemical reactions, radiant energy, and the influence of magnetism on conductors are a few ways in which voltage may be produced.电压除了能通过一些类型不同的材料相互摩擦产生之外，化学反应，辐射能，磁场对导体的影响也是产生电压的方法。
11.Kirchhoffs Current Law states that the sum of the currents entering a node must be zero.基尔霍夫电流定律陈述了流过一个节点的电流总和必须为零。
12.Kirchhoff's Voltage Law states that the sum of the potential drops around a loop in a circuit must be zero.基尔霍夫电压定律陈述了在电路中的回路的点位下降总和必须为零。
