At relatively high pressure, in addition to electromagnetic field and electron's Coulomb scattering by gas molecules, plasmainstability would result in decrease of propagation efficiency.
而较高气压时，束电子除受自身电磁场作用及库仑碰撞散射外，等离子体不稳定性使束流传输效率明显降低。

According to this model the instability process in plasma consists of two phases, namely, the thermal explosive phase and the steady annihilation phase.
