不稳定性产生的可能机制是由于电子束穿过低密度本底等离子体的漂移速度超过离子声速而激发起来的。
It is suggested that the instability is excited in the low density plasma when the electron beam drift velocities exceed the ion acoustic speed.
当再入目标高超声速穿越大气层时，将产生等离子体鞘套和尾流，其雷达散射特性受到目标包覆等离子体参数变化的影响而产生剧烈波动。
While the reentry target passes through the earths atmosphere at ultrasonic speed, the RCS of the reentry Capsule changed violently because of the plasma sheath and wake.
