中文摘要：

采用谱拟合法，劈裂算符法对处于限制势中的氢原子与激光场的相互作用进行了布居分布的数值计算，通过模拟实验与分析，结果表明加了限制势之后，通过降低激光场强度在减少布居泄漏的同时可以保证Rabi振荡频率不变．用这种外加限制势的方法在不改变Rabi振荡频率时可以将布居泄漏降低到原来的1％以下．

英文摘要：

Use spectral fitting method, split-operator spectral method, solving the time-dependent Schrodinger equation of hydrogen system with confined potential enery,simulatel the process of laser interacting on hydrogen system. The result indicate that keep Rabi oscillate frequency unchanged decrease the laser intension can decrease population-leak considerably. In this way, decrease population-leak at least to 1% of hydrogen system without confined potential enery.
