中文摘要：

在超临界CO2中加入合适的表面活性剂后形成反胶束体系，是一种提高极性、亲水性以及高相对分子质量物质在超临界CO2中溶解性的有效方法。目前对超临界CO2中反胶束的研究主要集中在对其结构信息的研究，就反胶束结构分析测试以及反胶束模型模拟计算的常用方法进行了简要介绍，如动态光散射法（DIS）、小角中子散射法（SANS）、小角X光散射法（SAXS）、核磁共振光谱法（NMR）、Monte Carlo格子模拟法等方法。

英文摘要：

Reversed mieelles were formed by adding appropriate surfaetant into supereritieal earbondioxide. It would be an effective way to improve the solubility of some polar, hydrophilie and maeromoleeular substances in supereritieal earbon dioxide. Research works on reversed mieelles were now focusing on its structure information. Some reseseh methods during the reversed mieelle study were introduced, such as dynamic light scattering, small angle neutron scattering, small angle x - fas scattering, nuclear magnetic resonance, and Monte Carl lattice simulation.
