| 摘 要： | 通过分析从等离子体发生器中喷出的等离子体在均匀、恒定和相互正交的电场和磁场中的加速运动情况，发现一些失稳运动．失稳运动的产生使带电粒子的运动分散且速度减慢，严重影响等离子体推力的提高．经研究发现，电场强度的变化不会引起失稳运动的产生，而磁场改变带电粒子运动的周期，它对带电粒子稳定运动起着至关重要的作用．

| Abstract: | Through analyzing the accelerated movement situation of the plasma which spouts from the plasma generator in uniform,constant and mutual orthogonal electromagnetic field,some destabilization motion is discovered.The destabilization motion of the charged particle make their movement deconcentrate and their speed weaken,which affects the increase of plasma thrust force seriously.After researching the destabilization motion of plasma,that the change of electric-field intensity can not cause destabilization mot... |
