Specially, the thermal lens effect is intensified due to the long tail attached to pulse, which leads to decreasing of conversion efficiency if pulse repetition rate is enhanced.
特别由于脉冲附带长的拖尾加剧了热透镜效应，使得脉冲重复频率的增加引起转换效率的降低。

With matrix conversion of geometry optics as a basis, simulation and modeling for complex multi-lens imaging optical system for four-quad splitting are carried out through light ray trace.
以几何光学的矩阵变换为基础，通过光线追迹的方法，对四象限分光的多透镜成像复杂光学系统进行仿真建模。

By using the convex lens to focus the solar energy, the use amount of the crystal silicon batteries is largely reduced and the energy conversion rate is improved.
