摘要
运用油松分布的性质和二元泰勒级数展开方法，研究了初始处于下能级的级联三能级ＪＣ模型中的原子与两个初始相于辐射场的相互作用，得到了原子能级算符、光子数和偶极矩算符的平均值的近似解析解，与前人数值结果相比，更加明确地反映了系统的量子效应。
The interaction of a cascade three-level atominitially in the low state with two initially coherent fields is .investigated by using the properties of Poissonian distribution and Taylor expansion for the means of the atomic level occupations and the photon numbers as well as the dipole moments. Compared with the results of the numerical computation, the analytical results represent more clearly the quantum effects of the system
