The Laser particle Sizer may obtain the information of particle size and distribution by detecting the relative energy scattered by the particles, with the fixed wavelength.

激光散射法粒度测试仪在固定波长下，通过探测粒子场在前向某个小角度范围内的相对散射光能而得到粒子的尺寸分布信息。

Based on these ideas, a wavelength assignment algorithm is presented. For an optical ring with any fixed conversion mode, the algorithm can give a good assignment scheme.

基于这些算法，进一步提出了一个波长分配算法，该算法对于环形光网上的任意固定转换模式都能给出一个较好的波长分配方案。
