| 摘 要： | 根据球对称激光等离子体空气冲击波在自由空间中传输的约束条件，对多光子非线性Compton散射的强激光等离子体空气冲击波波前的传输特性进行了研究，给出了散射下空气冲击波波前的运动方程，并进行了数值模拟。结果表明：该冲击波的衰减过程不仅与爆炸源和爆炸过程的特性、释放总能量、空气的弹性有关，而且还与散射有关，散射效应使冲击波的初始半径增大，衰减过程加快，能量转移率提高；数值模拟与实验结果符合得很好。

| Abstract: | By comparing the kinematical equation of a shock wave in free air,the study of transmission characteristics of the laser plasma shock wave in Compton scattering is presented.The results show that the attenuation course of the kinematics of he laser plasma shock wave is related not only with the explosion fountainhead and the characteristics of the explosion course,total energy release,air elastic,but also with multi-photon nonlinear Compton scattering.Because of the scattering the initial radius of the shock wave increases,the attenuation course shortens,the energy metastasis efficiency rises.The results of the numerical analysis and the actual values of the shock waves in air by a way intense explosion are very tallying. |
