查询词典 luminous beam

Ponderomotive force of laser beam propagating in plasma could become stronger as the intension of laser beam strengthening , and in fluid mechanics ponderomotive force is related to implicate term, so implicate term could become stronger as laser beam's strengthening and couldn't be ignored.

当在等离子体中传播的激光脉冲达到一定强度时，有质动力会变得比较强。而在流体力学方程中有质动力一项与牵连项相关。因此当激光达到一定强度的时候，流体方程中的牵连项也会变得比较强，不可以被忽略。
