摘　　要：用稳态荧光法测定合成的Gemini阴离子表面活性剂水溶液的聚集性质,并与其它方法如电导法、表面张力法测定的结果进行对比,结果吻合,表明荧光法作为一种测定Gemini阴离子表面活性剂水溶液聚集性质的方法是可行的,并对Gemini和单基表面活性剂在临界胶束浓度Ccmc前后荧光相对强度变化规律做了简要分析。The aggregation properties of synthesized Gemini anionic surfactant solution were measured by (steady-)state fluorescence method.The measured results were in accordance with the results by other methods such as electronic conductivity and surface tension,therefore,steady-state fluorescence method was proved to be feasible as a method of measuring aggregation properties of anionic Gemini.And the variational rule of fluoresence intension close to critical micelle concentration C_(cmc) of Gemini and monomer-surfactant was briefly analyzed.
