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.
