Thus Planck'slaw can be used as a good approximation.
因而布朗克定律可以作为一个较好的近似计算。

It is not always suitable to use Planck'slaw or Stefan-Boltzmann's law to describe the relation between brightness temperature and radiance for a wide band sensor.
对于宽波段传感器，不一定能直接由普朗克定律或者斯蒂芬玻尔兹曼定律建立温度与辐射亮度的关系。

Although silicon is an indirect semiconductor, light emission from silicon is governed by the same generalized Planck's radiation law as the emission from direct semiconductors.
