摘　　要：采用升温法测定微乳剂的浊点,研究各因子对微乳剂浊点的影响,结果表明:表面活性剂的HLB(亲水亲油平衡)值增大,其亲水性增强,微乳剂的浊点升高。水中Ca+、Mg+浓度增加,微乳剂的浊点降低。pH对微乳剂的浊点无明显影响。助表面活性剂的碳链越长,对微乳剂浊点影响越大,浊点下降越多。The method of temperature increasing was used to determine the effect of different factors on the cloud point of microemulsion, the result showed that with the number of HLB （hydrophile lipophile balance）of surfactant increasing, the cloud point of microemulsion increased, but to the concentration of Ca^＋, Mg^＋ and the length of alkyl chain of co-surfactant, despite the increasing of its value, the cloud point of microemulsion decreased respectively, pH hardly had effect on the cloud point of microemulsion.
