根据反向积分原理编写了流场反演程序，并开展了程序验证计算。在反演区域内，由临界面速度反演出与辐射流体力学程序MULTI计算结果几乎一致的结果；由Saturn 加速器上实验测试的单个样品后自由面速度反演出了加载压强历史、多种厚度样品后自由面粒子速度历史等信息，与文献对比发现，反演结果与由加速器工作电流推出结果、WONDY程序计算结果、实验测试结果相吻合。本工作为即将开展的激光驱动准等熵压缩实验奠定了技术基础。

Inversion codes were completed based on principles of backward integration, and simulations were performed by the codes. The results inverted from the particle velocities of interface are in consistent with the ones from MULTI. Moreover, the loading pressure curves, free surface velocities inverted from some free surface velocities are the same as the experiments results obtained from Saturn accelerator, and those both obtained by WONDY codes, and deduced from current shapes of the accelerator. This work can provide important supports for laser-driven ramp compression experiments in future.
