英语语法分析

The measurement system is based on facular-orientation theory of position sensitive detector (PSD).

测量系统基于PSD传感器的光斑定位原理。

The temperature is achieved by controlling the laser power, the facular diameter and the acting time.

涂层表面的温度是通过控制激光功率、光斑直径、作用时间来实现。

By the simulation of a theoretical model, the facular intensity distribution curve versus etendue is achieved.

根据理论分析模型，实际模拟了输出光斑的光能分布与光学扩展量的关系曲线。
