In view of the facts that traditional graphical construction has less pertinence to stray light and tracing different incidence angle rays is fatiguesome and more likely to omit some rays, we proposed a reverse ray-trace method based on the ray reversibility. According to the method, a dot-matrix source was set at the image plane. Each dot emitted rays to fully cover the system aperture. A detector surface, large enough to receive all possible rays from the source, was set at object plane.

针对传统作图法设计遮光罩的针对性不强，且追迹不同入射角的光线繁琐、容易遗漏的问题，本文提出一种逆向追迹法，依据光的可逆性，在像面处设置点阵面光源，每一点都发出充满系统孔径的光束，在物面设置足够大的探测面，使之有充足的余量记录所有到达物方的光线，利用该方法可以在探测面上直观地区分出非成像杂散光。

The results showed that the highest yield of GLP among six strains was ShuShe.The effects of carbon source, nitrogen source, salt and the optimum initial pH value of medium on GLP produced by ShuShe were studied in liquid and solid fermentation respectively. The liquid and solid fermentive medium of high yield was selected by orthogonal experiment.
