| 摘 要： | 微乳液是指由水（盐水）、油（烃）、一种或几种表面活性剂组成的热力学稳定体系，这类体系具有低粘度、各向导性、透明或半透明的性质[1]，微乳液在许多工业实际问题中，例如润滑、以洗涤、催化等方面得到了应用[2]，近年来，微乳液和反向胶束中酶催化技术的开发[3]以及分离蛋白质中的应用[4]，使微乳液在生化技术研究中倍受青睐．与过剩盐水相和过剩油相达三相平衡时的微乳液即为中相微乳液。中相微乳液具有既可增溶水又可增溶油的特殊性质，并且微乳液与过剩水相和过剩油相间的界面张力（飞uw和7；n。；）极低顺干2．0。10－’1liN·111…

| Abstract: | The microstructures of the middle-phase microemulsions were studied by using ESR and NMR techniques. The results from the two methods show that the microstructures of the middle-phase microemulsions undergo the change from O/W to bicontinuous(BC), and to W/O with the variation of NaCl concentration, and BC structure includes O/W and W/O. The models of the bicontinous structure were constructed on the base of the studies. |
