用法例句

By introducing PW method into modern advanced optical design software, it can automatically change glass according to the designer s needs to meet the requirements of rational distribution of primary aberrations in the entire optical system.

运用PW法来更换 光学系统中的玻璃材料使初级像差减小或按要求重新分布像差是可行的。

Then study the principle of zoom deeply,and introduce the pw method with which could count an initial configuration,base on which ,programmes were workouted,and an example was established.

接着深入研究了变焦光学系统的变焦原理,讲述了pw法求解初始结构的方法,以此为基础编制了计算程序,求解了一个具体的实例,另外给出了更加实用的光学自动设计方法,采用此方法设计了三倍变焦手机镜头,保证各个焦距位置的良好像质,并最终拟合出合理的变焦凸轮曲线。
