摘　　要：对M ikhailovsk ii的横振荡色散关系的物理模型进行数值模拟。所得结果在极端相对论下(α=0.3)不仅与M ikhailovsk ii的理论相吻合,还得到了M ikhailovsk ii没得到的1<vp<10范围内的色散关系,而且将α取不同值的色散关系全数据化地模拟了出来。Numberical simulation methods of Mikhailovskii＇s physics model about dispersion laws of transverse oscillation in relativistic plasma oscillations are presented. The method is proved feasible, because the result of the methods inosculates with the result of Mikhailovskii＇s theory in the uhrarelativisty （α = 0.3）. And we get the dispersion laws at 1 〈 -↑vp 〈 10,which Mikhailovskii cant get in his theory. The numerical simulation methods is also get the dispersion laws when α is deplace by different value.
