摘要

摘要: 利用二级轻气炮在3.75~57.87 GPa 压力范围内，对体积比为10∶10∶1的液态水-苯-壬基酚聚氧乙烯醚混合体系进行了动高压加载实验，获得了10个Hugoniot数据。拟合结果表明，该混合体系的D-u关系可近似用直线方程D=1.407+1.503up描述，拟合精度约为0.102。混合体系H2O-C6H6-C35H64O11的冲击压缩实验结果基本符合体积相加原理，而在给定的实验压力区间内，冲击绝热曲线发生多次拐折的事实意味着该系统可能在6 GPa、10 GPa和30 GPa压力点附近发生了多次结构性相变。另外，还讨论了Lawrence-Berthlot混合规则中修正因子对高密度条件下指数-6型相互作用势排斥部分的影响。

Abstract: A series of dynamic loading experiments have been successfully conducted for liquid H2O-C6H6-C35H64O11 (OP-10) mixture of which the voluminal proportion is 10∶10∶1 on a two-stage light gas gun, and 10 Hugoniot data in pressure range from 3.75~57.87 GPa are obtained. The linear regression for these experimental data indicates that D-u relation of the mixture can be approximately expressed as D=1.407+1.503up, and the standard deviation is 0.102. The shock compressibility of the liquid system are basically consistent with the estimates from volume adding theory. The knees occurring at 6 GPa, 10 GPa and 30 GPa, possibly suggest the successive structural phase transitions. Furthermore, the effect on repulsive part of the interaction potential, e.g. Exp-6 type potential, is analyzed by modifying three coefficients in the Lawrence-Berthlot's mixing rule.
