| 摘 要： | 电磁场在磁化等离子体中传播会产生分裂现象，这种分裂现象的发生与等离子体本身的参数等因素有关，当这些因素满足某一关系式时，双折射现象将会消失。如果波在等离子体中发生分裂，分裂后两列波之间的振幅会满足某一函数关系式，而且这一关系式中必包含反射角和入射角的因子。分裂后的两列波频率仍然相等．它们产生稳定干涉的波节间距同样与等离子体参数等因素有关。

| Abstract: | The propagation of electromagnetic field in plasm will produce splitting phenomenon,which has the relation with parameter of plasm itself,propagating direction of the wave,etc.When these factors agnee.with a certain relation,double-refraction will disappear.When the wave happens to split in plasm,the amplitude between the two waves produced by splitting will pill for a certain relation,in which there certainly include angle of the two waves after splitting will also be stable interference peaks which was produced by the splitting,has something to do with plasm parameter as well. |
