工作面

The angle between the cutting edge of a tool and a plane perpendicular to the working surface to which the tool is applied.

倾角：某工具的切边和与使用这个工具的工作面垂直的飞机之间的角度

The relation of the surface shape error to f-number and relevant spherical radius was achieved according to the reducing analysis model ignoring the local f-number. Two kinds of rhombic prism model are established by ZEMAX. According to the simulation results from ZEMAX, the correctness and limitation of the former methods are proved and analyzed. The results are used to analyze the effect of the surface shape error of the rhombic prism on parallelism of the emergent beam. The assignation plan of the surface shape error for each working surface is presented.

根据忽略局部光圈数的简化分析模型，获得面形误差对应光圈数与相关球面半径的关系，通过几何处理方法，求得一定面形误差对应的球面半径与平面倾角的关系，将斜方棱镜的工作面倾斜一定角度，运用折射定理，将具体面形误差转化为相应平面的倾斜角度，得到出射光相对于理想光轴的倾斜角度及其关系式，并在ZEMAX中建立斜方棱镜的两种模型。

The upper member of the protective cover generally overlies the upwardly facing surface of the robot arm while the peripherally extending sidewall generally overlies the outwardly facing surface of the peripherally extending sidewall. In similar fashion, a protective plate of thin-walled plastic material impervious to fluids may also be removably attached to the downwardly facing surfaces of the robot arm and includes a peripheral rim generally coextensive with the peripherally extending sidewall of the link and proximate the lower rim of the protective cover when both the protective cover and the protective plate are so attached.

以相似的方式，一个由液体不能透过的薄壁塑料制成并且也被可拆卸地固定在该自动臂的下工作面(34)上的保护板(46)，该保护板包括一个周边边缘(48)，当保护盖(38)和保护板(46)都这样地固定在该自动臂上时，该周边边缘大体上与该连杆的沿周边方向延伸的侧壁(36)共同地延伸，并且靠近该保护盖的下边缘。
