| 摘 要： | 用量子Ｍａｘｗｅｌｌ－ＢｌｏｃｈＣ－数方程讨论了存在均匀消相阻尼的一维稀薄等离子体系统中电场和极化的发展过程及相干特性，给出了线性阶段的解析结果和非线性阶段的数值结果。数值结果显示了电场和极化的发展过程及随机源对它们的影响。最后给出了电场和极化的相干度及自由电子对相干度的影响。当等离子体频率远小于辐射频率时，自由电子的作用可以忽略。

| Abstract: | The quantum Maxwell-Bloch C-number equations are used to investigate the developing process and coherence properties of electric field and polarization in one dimensional tenuous plasma system in which the homogeneous dephasing damp is exist.The analytic result in linear stage and the numerical result in noulinear stage are shown. Numerical result of the developing process of electric field and polarization and the influenee of stochastic source upon them are given. The coherenee of electric field and polarization and the influence of free electron upon coherence are given too. When the influence of free electron can be negligible. |
