It is found that , the quasi - isentropic curve is located between the hungoniot curve and isentropic curve , and more close to the latter 它介于冲击hugoniot线和等熵线之间,并更接近于等熵线。
It is considered that , the physical process of generating quasi - isentropic compression on target via flier - plates with graded wave impedance can be stated as follows : a series of hungoniot curves with different original state forms the p - v relation of the target when impacted by a flier - plate with graded wave impedance 梯度飞片撞击靶板获得的p - v线是一组通过靶材料不同起始状态点的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” 。
Basing on the two order tangency at initial point between isotropic curve and hugoniot curve , a new method for calculating cold energy cold pressure and cohesive energy for solid is presented in the paper , comparison with experimental data manifest that this method is very good and can be applied 利用在初始点等熵线和冲击绝热线二级相切的性质,给出了一种可用于计算固体冷能冷压和结合能的新方法,并推导了利用hugoniot参数计算结合能的公式。与实验数据的比较表明,这种方法是有效可行的。
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。
