摘要
本文研究了处于热平衡状态的理想腔内与原子多光子相互作用的单模热辐射场的熵特性，讨论了平均光子数和跃迁光子数对场熵演化的影响。
In this paper, we investigate the entropy properties of a single-mode thermal radiation field interacting with an atom in multiphoton process at thermal equilibrium in an ideal cavity. The effects of the mean photon number and of transition photon number on the evolution of the field entropy are discussed.
