使用两级轻气枪在 19-210 GPa 的冲击压力范围内测量苯、聚丁烯和聚乙烯的动态状态方程数据。使用快速五通道光学高温计测量了苯和聚丁烯的冲击波前光谱光度。苯和聚丁烯高于 20 GPa 的压力-体积 Hugoniot 数据与冲击碳氢化合物的统计力学模型和 Gruneisen 模型一致，碳氢化合物分解成致密类金刚石相中的碳和凝聚分子相中的氢的两相混合物。已发表的 Hugoniot 苯压力高达 13 GPa 的数据与苯保留其 C6H6 分子结构的模型非常吻合。苯中激波前沿的测量有效辐射温度远低于假设热平衡时理论上计算的温度。这种巨大的差异表明测量的有效辐射温度不是化学平衡温度...
Dynamic equation‐of‐state data for benzene, polybutene, and polyethylene were measured in the shock pressure range 19–210 GPa using a two‐stage light‐gas gun. Shock‐front spectral luminosities were measured for benzene and polybutene using a fast five‐channel optical pyrometer. The pressure–volume Hugoniot data above 20 GPa for benzene and polybutene are in agreement with both a statistical mechanics model and a Gruneisen model for shocked hydrocarbons decomposed into a two‐phase mixture of carbon in a dense diamond‐like phase and hydrogen in the condensed molecular phase. Published Hugoniot data of benzene up to 13 GPa are in good agreement with a model in which benzene retains its C6H6 molecular structure. The measured, effective, radiating temperatures of shock fronts in benzene are substantially lower than the temperatures calculated theoretically assuming thermal equilibrium. This substantial difference suggests that the measured, effective, radiating temperatures are not the chemical equilibrium tem...
