摘　　要：提要本文研究的中相微乳液体系是由石油磺酸盐(3A)、正丁醇、异丙醇、煤油以及一定矿化度的矿化水所形成的。探讨了三种聚丙烯酰胺的存在对中相微乳液形成的影响和引起的相态、增溶参数、粘度、界面张力变化的规律。The system studied is a middle phase microemulsion consisting of petroleum sulphonate (3A),n-butanol,isopropanol,kerosene and mineralized water.The etfect of three samples of polyacrylamide on microemulsion forming and on the rule of change of phase state,so- lubilizing parameter,viscosity,and interfacial tension are discussed.Experimental results show that added polyacrylamide has no effect on the formation of middle phase micro- emulsion,however,increasing concentration of the polymer will lead to decreasing the middle phase volume of microemulsion,and to slightly increasing the interfacial tension between middle amd low phases(yet remaining in Order of 10^(-3) mN/m),but no obvious change is observed in middle phase viscosity.
