中文摘要：

研究了耗散场腔中，二能级原子与单模辐射场在相互作用过程中熵的关联情况．结果表明：原子与耗散场之间存在熵交换现象，更重要的是证明了它们之间的熵交换需要满足一定的条件．

英文摘要：

The entropy exchange between a tow-level atom and a sing/e-mode radiation field is studies in a damped system. The results show that there is an entropy exchange phenomenon between atom and field. Especially, it is prove that there is a condition for entropy exchange between atom and damped field.
