摘要 用降温DSC曲线研究了石蜡的液-固相转变,取DSC曲线上石蜡冷却固化放热峰前沿切线与基线延长线的交点为固化点,即所谓熔点。结果表明,与现行方法比较,该DSC法方便、准确,有很好的重复性和精确度。 The phase transition from liquid to solid of paraffin was studied with DSC curves by cooling method. The point crossed by base line and tangent line of the rising edge of exothermic solidification peak of paraffin was selected as its solidification point (Tc'), namely the melting point. The results show that in comparison with traditional methods, the DSC method presented in this study is more convenient and exact and has good accuracy and repeat-ability.
