摘要
由正十六烷、油酸钾、正己醇和水组成的微乳液，在水油比为１时产生异常流变性。本文研究ｐＨ值和盐类物质对微乳液异常流变性的影响，对产生异常流变性的微乳液微观结构有了进一步的理解。
The microemulsions studied are spontaneously formed upon mixing hexadecane, potassium oleate,hexanol and water in water-to-oil ratios (WOR) near to unit.The negative thixotropy/pH value relationship of the microemulsion with WOR=0. 8 goes through a maximum at pH=9. 3 (T=25℃ ). In enhancing negative thiotropy the inorganic salts are arranged in order NaCl>BaCl_2>LaCl_3 for the microemulsion with WOR= 1. 2 and in order LaCl_3>BaCl_2>NaCl for that with WOR= 0. 8. The energy dissipated as heat is determined by using thermal activity monitor of type 2277 for the microemulsions after violent turbulence applied and is explained in terms of structural recovery of the systems from a disturbed , chaostic arrangement to an ordered , regular one.
