摘　　要：介绍了用差示扫描量热法(DSC)测定高密度烃燃料冰点的原理和方法,并对测试中的主要影响因素进行讨论。结果表明,当高密度烃燃料冰点在-80℃以下时,该方法具有较好的重复性和再现性,可作为高密度烃等低冰点燃料的常规检测方法。Principle and method of measuring freezing point of high-density hydrocarbon fuels by differential scanning calorimetry （DSC） are introduced, and the main influence factors during testing are discussed. The result shows that DSC method has good repeatability and reproducibility, can be used as an routine measuring method for the low freezing point fuels such as high-density hydrocarbon and so on when the freezing point of high-density hydrocarbon fuels is below -80℃.
