Flux distributions of the hot spot for several different incident angles, which have covered all the extreme cases of operating conditions have been simulated.
我们在不同入射角情况下，对热点的聚光比分布做了分析，覆盖了实际运行中所有的极端情况。

The transmission of the optical system is the ratio of the outgoing light flux and the incident light flux.
透过率是指光学系统的出射光通量与入射光通量的比值。

Thermally induced vibration of space structures, which are subjected to incident solar heat flux and emitting thermal energy by radiation, is one of typical modes of structural failure.
