摘　　要：研究了非共振情况下外加经典激励场(仅激励原子)的Jaynes-Cummings(J-C)模型中自发辐射场的场熵演化特性和光场的熵压缩特性,给出了受外场、耦合系数及失谐量影响的场熵及熵压缩曲线。The field entropy evolution and it＇s squeezing properties of the spontaneous emission in the Jaynes-Cummings system with the atom driven by and detuned from the external classical field are studied, we get the Evolution curve of the field entropy and it＇s squeezing properties. It shows that the field entropy is influenced by the external field and the dipole coupling constant and the frequency detuning.
