英文摘要	绘制和分析了十二烷基三甲基溴化铵(DTAB)-月桂酸钠(SL)组成的表面活性剂混合体系相图,系统研究了温度和无机盐等因素对该体系表面活性剂双水相(ASTP)影响的规律性.结果表明:与富含负离子表面活性剂双水相(ASTP-A)相比较,富含正离子表面活性剂双水相(ASTP-C)区域更大、更稳定;温度升高,无机盐 (NaBr)的浓度增大,都引起ASTP体系上相体积的减小和下相体积的增加;囊泡普遍存在于ASTP的上下相之中.; The phase behavior diagram has been drawn and analysed in DTAB - SL mixed system and the influences of temperature and inorganic salt upon "aqueous surfactant two-phase (ASTP) " have been studied systematically. The results show that ASTP region when cationics is in excess(ASTP-C) is larger and stabler than that when anionics is in excess (ASTP-A) (to see Fig. 1). The higher the temperature and the inorganic salt concentration (NaBr), the less ratio of upper to lower volume(V-up/V-low) in ASTP system(to see Table 1 similar to 2). Vesicles generally existed in upper and lower phases of ASTP.; 陕西省教育厅资助项目; http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:000172252600013&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=8e1609b174ce4e31116a60747a720701 ; SCI(E); 中文核心期刊要目总览(PKU); 中国科学引文数据库(CSCD); 2; 11; 1027-1030; 17
