At relatively high pressure, in addition to electromagnetic field and electron's Coulomb scattering by gas molecules, plasma instability would result in decrease of propagationefficiency.
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。

Efficiency of the combined procedure was evaluated by analyzing supersonic shocks and shock propagation behaviors for both the steady and unsteady high-speed compressible flows.
通过稳态和不稳态的高速可压缩流体超音速激波和激波传播特性的分析，可以评估该算法的效率。

To verify the accuracy and efficiency of this method, the distortion of the wave propagation on two typical mild slopes are simulated numerically.
