Based on geometrical optics theory, the re-radiation is analysed by using aperture field method.
根据几何光学理论，利用孔径场法进行了分析。

Most of the energy is lost through heat loss through the reactor's wall or through the re-radiation of sunlight back through the device's aperture.
而大多的能量都通过反应器壁的热耗散，或者通过装置开孔的太阳光再发散损失掉了。

According to the nonlinear re-radiation characteristic of semiconductor PN node, the nonlinear node detection system for semiconductor junction targets based on second harmonic reception is designed.
