摘要
研究两能级原子与外部环境（热库）的相互作用。对于任意强度耦合的情况，给出求解原子约化密度矩阵的方法。针对实例，得到原子约化密度矩阵非对角元，分析原子状态的消相干特性。
Interaction of two -level atom with a thermal radiation field is studied. The atom's reducible density rectangular array is gived by the intensity-dependent coupling. Taking f(N)=a+a for example,the non-opposite angle element of atoms' reducible density rectangular array is obtained. The decoherence properties of atom is analyzed.
