【摘要】 根据激光等离子体波前在固体中传播的约束条件,导出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,波前传输半径和速度随时间而迅速减小.更多还原

【Abstract】 Under the constraint condition of laser plasma wave transmitting in solid, a laser plasma wave transmission formula at mediate and far field is given. QuasiMAHE number is definitude for the first time. The concussions that 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 quick decrease along with time changing have been worked out.更多还原
