1·The control systems inside machines used to be physical: gears and levers and cams.
在过去，机器内部的一整套控制系统是由硬件组成的：传动装置，杠杆和凸轮。
2·I am trying to confirm the shipment of the first 3000 sets of cams from your facility in Shanghai.
我正在设法确定从你们厂在上海运出的第一批3000套的凸轮的运输情况。
3·The metal shaft, called the camshaft, typically has individual cams for each valve in the engine.
那金属轴叫凸轮轴，翣在发动机里的每个气门一般有各自的凸轮。
4·The metal shaft, called the camshaft, typically has individual cams for each valve in the engine.
那金属轴叫凸轮轴，在发动机里的每个气门一般有各自的凸轮。
5·This paper establishes the contour surface equation of a torus CAM and presents a pressure Angle formula, it provides a simple and efficient method for designing this kind of cams.
建立了环面凸轮轮廓曲面的解析方程，同时给出了压力角计算式，为此种凸轮的设计提供了一种简单有效的方法。
