摘　　要：将Mikhailovskii色散关系的理论用于费米分布的等离子体中,分别对纵振荡和横振荡进行数值模拟。结果表明,该方法得到的色散关系在极端相对论条件下不仅与Mikhailovskii的理论相吻合,还得到了Mikhailovskii没有涉及的范围内的色散关系。模拟得到了费米分布等离子体不同温度下纵振荡和横振荡的色散关系。A numberieal simulation method of Mikhailovskii＇s physics model about dispersion laws of relativistic plasma of Fermi distribution is presented and the method is proved peasible. The result of the method inosculates with the result of Mikhailovskii＇s theory in the ultrarelativisty, We get the dispersion laws which Mikhailovskii can＇t get in his theory. The dispersion laws in different temperature are also obtained by using the numerical simulation method.
