The physical process of generating quasi - isentropic compression on target via flier - plates with graded wave impedance might be considered as the successive overlap of a series of small shock loading waves generated by the transition layers in the flier - plate . as a result , the p - v curve of the target was a quasi - isentropic compression curve , which consisted of small hugoniot curves ( similar to isentropic curves ) from different original states , and was located between the hungoniot curve and isentropic curve but closer to the latter 波阻抗梯度飞片对靶板的压缩过程是一系列弱冲击加载波相继发生作用叠加的结果，靶板由此获得的p - v线是一组通过不同起始状态点的hugoniot线的连线，这条连线可以近似看作是由小段小段等熵线连接而成的准等熵线。
