The concussions of laser plasma wave MAHE number in solid is equal to the product of quasi-MAHE number of laser plasma wave with electromagnetism phonon and the MAHE number with airborne acoustic velocity, and the laser plasma wave propagation radius and velocity decrease along with time changing quickly.
根据激光等离子体波前在固体中传播的约束条件,导出了固体中激光等离子体波前中远场传播公式,定义了准马赫数,发现固体中激光等离子体波前声子的马赫数等于该波前相对于电磁声子的准马赫数与电磁声子相对于空气中声速马赫数的乘积,波前传播半径和速度随时间而迅速减小。
补充资料：飞行马赫数
飞行马赫数：
变称飞行m数。飞行器的飞行速度与其飞行高度上音速的比值。因奥地利物理学家e·马赫最早使用这一比值研究炮弹的高速飞行而得名。飞行速度大于1为超音速飞行，小于1为亚音速飞行。
