stray radiation meaning in Chinese

漫辐射
杂散辐射
杂散损射

Two methods of calculating stray radiation are discussed in the paper , and calculation examples are given for each method
本文介绍了两种系统杂光计算方法，各自给出了计算实例。
Although analytical formulas are not accurate enough to calculate stray light , they can help designer to distinctively understand the cause of formation of seven types of stray radiation and their influences , so as to adopt proper methods to restrain stray light and to optimize baffle design
采用公式法计算系统杂光，精度虽然稍差，却可清楚地了解系统七种类型杂光的成因和影响，便于有针对性采取抑制措施，优化遮光设计。
Space optical system , especially space infrared optical system , cryogenic optical system and some huge space - based telescopes , all work in the environment where there is strong radiation ( such as sun etc . ) out of the field of the system . because of diffraction of the entrance pupil and diffuse scatter of all inner surfaces , the strong stray radiation will reach the detector of the system
空间光学系统，特别是空间红外光学系统、低温光学系统以及某些大型空间望远镜，都工作在系统视场外有强烈辐射源(如太阳等)的“恶劣”环境中，这些强烈杂光辐射经过光学系统孔径的衍射，以及结构与光学件表面的散射，到达系统像面形成杂光。
