| 摘 要： | 通过分析三能级原子与拉曼激光相互作用退化的二能级演化方程组，发现通过代换法能将其转化为常系数，可十分方便地求得方程组的解．再将这种方法推广到三能级演化方程组，也可化为常系数，使得精确求解筛选速度的受激拉曼跃迁的演化方程成为可能．

| Abstract: | It analyzes the interaction of three -level atioms with Roman laser in this paper, which could degenerate into two- level evolution equations and resolved easily by transforming them into linear differential equations with substitution. Then the three -level evolution equations are transformed into linear diffemtial evolutions in the same way, which provides a probability of solving the evolution equations of velocity - selective stimulated Raman transitions accurately. |
