摘　　要：The phase behavior and property of aqueous two-phase system formed by SS(PS)/CTAB/NaBr/H2O mixture had been studied.The results indicated that there was only one ATPS region in the both systems,and the system with PS showed a peculiar inversion of ATPS.As a function of composition,the volume ratio appeared a turn on its relation curve.It was surposed that one side of the turn was ATPS which contains cubic liquid crystal,the other dosen’t.When the ratio of top vulume to bottom volume was close to 1,the ATPS forming time was the shortest,and vice versa.The phase behavior and property of aqueous two-phase system formed by SS（ PS）/CTAB/NaBr/H2O mixture had been studied. The results indicated that there was only one ATPS region in the both systems,and the system with PS sbowed a peculiar inversion of ATPS. As a function of composition, the volume ratio appeared a turn on its relation curve. It was surposed that one side of the turn was ATPS which contains cubic liquid crystal ,the other dosen＇ t. When the ratio of top vulume to bottom volume was close to 1, the ATPS forming time was the shortest, and vice versa.
