三.翻译下列句子
1.Although a cam and follower may be designed for motion, path, or
function generation, the majority of applications utilize the cam and follower for function generation.
虽然可以把凸轮和它的从动件设计为用于运动变换,路径变换或者函数变换,但大多数用途是利用凸轮和它的从动件做函数变换。
2. In the case of a disk cam with a radial (in-line) translating roller follower the smallest circle that can be drawn tangent to the cam surface and concentric with the camshaft is the base circle. 对于一个对心直动滚子从动件盘形凸轮,可画出的与凸轮表面相切且与轮轴同心的最小圆是基圆
3. Numerous applications in automatic machinery require intermittent motion. A typical example will call for a rise-dwell-return and perhaps another dwell period of a specified number of degrees each, together with a required follower displacement measured in centimeters or degrees.
在自动化机械中的许多应用需要间歇运动。一个典型的例子将要求一个含有上升一停歇一返回和可能另一个停歇的周期,每阶段经过一个指定的角度,伴随
着一个所要求的从动件的位移,这个位移以厘米或度来度量。
4.Any two mating tooth profiles that satisfy the fundamental law of gearing are called conjugate profiles.
任何满足齿轮传动基本定律的一对相互啮合齿廓称之为共轭齿廓。
5. Although there are many tooth shapes possible in which a mating tooth could be designed to satisfy the fundamental law, only two are in general use: the cycloidal and involute profiles.
虽然可以设计出有很多齿廓来满足传动装置的基本定律,但通常所使用的只有两种:即摆线齿廓和渐开线齿廓。

四.翻译短文
3. The four-bar linkage may take form of a so-called crank-rocker or a double-rocker or a double-crank (drag-link) linkage, depending on the range of motion of the two links connected to the ground link. The input crank of a crank-rocker type can rotate continuously through 360, while the output link just \length of the input link equals that of the output link and the lengths of the coupler and the ground link are also the same, both the input and output link may rotate entirely around or switch into a crossed configuration called an antiparallelogram linkage. [1] Grashof's criteria states that the sum of the
