incident radiation

基本解释

Thus the absorption of a system is the fraction of the incident radiation which is absorbed by the system.
因而一个系统的吸收率就是被系统吸收的入射辐射的份额。
Two types of incident radiation are considered, namely, the radiation normal to the boundaries and the diffuse radiation.
被考虑的两种入射辐射为垂直于边界面的入射和边界表面的表面辐射。
Thermal radiator that absorbs completely all incident radiation, whatever the wavelength, the direction of incidence or the polarization.
对于所有入射辐射，无论波长、方向或者偏振情况如何，均完全吸收的热辐射体。
