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。

Confusingly, a large f-stop number means a small hole, while a small f-stop number means a big hole.

比较混乱的是，大的f数值代表了一个小洞的开启，而小的f指则代表了大洞。

A large opening (small f-stop number) gives you a very shallow DOF, and a small opening (big f-stop number) gives you a much deeper DOF.

一个大洞的开启会带给你浅度景深，而一个小的开启则会给你一个深度景深。

当机械手读入当前位置刀具号后，我们只需人为按下所需选择的道具对应刀具号按钮，即可通过PLC控制电动机运转实现选刀。

The factorial of a number is defined as the product of all values from one to that number.

阶乘。 一个数的阶乘被定义为从 1 到该数字所有数字的乘积。

As a replacement of valve number 1 with Red Valve's Type A and pneumatic fail-safe system 700, valve number 3 has accomplished an improvement in the fluid dynamics of the system.

作为1号阀的替代品，美国红阀公司A型夹管阀和无故障气动系统700，也就是左图中的3号阀，极大地改善了流体介质的流动性。
