| 摘 要： | 本文由半经典理论推得了原子电离率随脉冲空间传输出现周期性起伏这一新的相干作用结果,这点与速率方程的预计相差甚远.文中定量说明了利用速率方程对同位素分离过程进行分析时产生的系统误差,为实验分析工作提供了依据.

| Abstract: | Numerical techniques are used to solve and compare the rate equations with the semiolassioal equations. Prom the semiclassical theory, it has been derived that the atomic ionizations vary oscill-attorilly with the pulse propagation distance, which is a new coherent optical phenomenon and far from the predication of the rate equations. This work explains quantitatively the theoritical errors which oome from the rate equations for the laser isotope separation, and forms the basis for the experimental analysis. |
