grey body radiation的意思|示意

The evolutional rules of linear entropy of field in the model of Jaynes-Cumming(JC) that acts each other with radiation field of a grey body are studied.

研究了与灰体辐射场相互作用的J-C模型中场的线性熵的演化规律，讨论了腔体吸收系数、入射场的光子数分布、热场的平均光子数对场的线性熵的影响。

The 3-d cloud of the cloudy sky is created through the particle system, and its radiation is obtained by grey body approximation.

位于空中的三维云团则采用粒子系统生成，并用灰体近似的方法得到其红外辐射值。
