摘　　要：报道了电导法测定十二烷基硫酸钠临界胶束（CMC）浓度实验中，温度控制和样品配制方法进行改进的主要结果，改善了实验的可操作性和可重复性，且明显地缩短了实验时间。In this paper, we studied the effects of temperature on the experiment of measuring water- solubility surface- active agent＇ s critical micelle concentration. The results showed that temperature had no effects on the critical micelle concentration of surface- active agent. Therefore in the experiment there is no necessary to use thermostat bath and this can simplify the experiment procedure.
