摘　　要：利用二级轻气炮对有机大分子乳化剂壬基酚聚氧乙烯醚(C35H64O11)进行了系列动高压加载实验。在11～42GPa冲击压力范围内测量了7个Hugoniot数据。结果表明,在17.8GPa处,该物质的Hugoniot曲线出现拐折。这一现象意味着在高温高压条件下,壬基酚聚氧乙烯醚体系的分子基团发生了结构性相变。A series of dynamic high pressure loadings to the organic macromolecular emulsion-nonyl phenol polyethyleneoxy ether (C35H64O11) are carried out on a two-stage light gas gun. Within the shock pressure range of 11-42 GPa, seven Hugoniot data of the substance are obtained. The experimental results show that an inflexion is presented on the Hugoniot curve at about 17.8 GPa, which may indicate a complicated phase transition is happened at the high pressure and high temperature.
