摘　　要：通过试验,确定了乳化液中油浓度热天平方法测定条件:试样量为3.5g;试验温度为125℃;加热时间为12min。热天平方法测定乳化液中油浓度精密度较好,相对标准偏差为0.58%;结果准确,与帕卡公司乳化液中油浓度试验方法比对,偏差均小于0.10%。该方法简单、快捷,分析周期仅为30min。The test conditions for oil concentration in emulsion were determined through experiment as; sample quantity 3.5g, test temperature 125℃ and heating time 12min. the accuracy of using thermobalance method to determine oil concentration in emulsion is satisfactory with the RSD of 0.58%; and comparison with Parker＇s test method resulted in a deviation less than 0.10%. As a simple and fast method, its analytical cycle is merely 30 rain.
