用Ｌａｎｇｍｕｉｒ－Ｂｌｏｄｇｅｔ技术测试了一系列沥青质膜、胶质膜的π－Α等温曲线。结果表明，原油中的沥青质和胶质在空气－水界面均形成不溶性膜；沥青质膜的性质随扩展溶剂芳香性的不同而不同，胶质膜的性质与沥青质膜有较大差异；胶质与沥青质的相互作用能显著地影响沥青质胶质混合膜的性质 Langmuir-Blodget technique was used to test the π-Α isotherms of a series of asphaltenes and glial films. The results show that asphaltene and gum in crude oil form insoluble membranes at the air-water interface. The properties of asphaltene membranes vary with the aromaticity of the extended solvents. The properties of the asphaltic membranes are different from those of asphaltene membranes. The interaction of the gum with the asphaltenes can significantly affect the properties of the asphaltene gum hybrid membrane
