为研究相对论性朗缪尔湍动特性，采用描述朗缪尔波与离声波非线性耦合过程的相对论性萨哈罗夫方程组，进行数值模拟，获得一系列朗缪尔波的时间演化图。图组形象地模拟出相对论性强朗缪尔湍动过程，图中给出不同相对论参数下朗缪尔波场强的最大值。研究表明，电子运动相对论性越强，朗缪尔波的演化耗时更长，朗缪尔波场越强，湍动越剧烈。这可为湍动加速或等离子体加热提供参考数据，对超强激光等离子体（或天体物理）中出现超热电子（或快离子流）的产生机制研究有一定的参考价值。

In order to study the characteristics of relativistic Langmuir turbulence,we numerically calculated the relativistic Zakharov Equations which had the nonlinear coupling process of Langmuir wave and ion sounds wave.A series of the evolution images of Langmuir waves and ion sound waves were obtained.From these figures,The process of relativistic strong Langmuir turbulence and the maximal intensity of Lang-muir turbulence are were offered from these figures.Our studies have shown that the stronger the relativis-tic electron moved,the longer the evolution time of the Langmuir waves were,and the stronger the intensi-ty of Langmuir was.The research conld provide some reference for turbulent acceleration or plasma heat-ing,which should be significative to the generation mechanism of extremely hot electron (or fast ion flow) from the super laser plasma (or astrophysics).
