摘　　要：差示扫描量热法(DSC)是高分子物理实验课程中的一个经典项目。传统的DSC教学实验通常只是孤立地测试聚合物样品的熔点或玻璃化转变温度,实验内容单一,缺乏系统性。本文通过对该实验原有内容的整合扩充,围绕该技术在高分子物理研究中的应用,设计了多套综合性实验项目包括热转变,物理老化,结晶度测定以及相容性表征的实验。该实验的设置可以使学生充分了解DSC分析的原理方法,学会使用该方法系统研究聚合物的分子运动与转变,激发学生的学习热情,培养学生综合利用高分子物理知识进行分析问题和解决问题的能力。Differential scanning calorimetry(DSC)is a classical project in the course of polymer physics experiments.The traditional DSC teaching experiment is only to determine the melting point or glass transition temperature of polymer separately.The experiment content is single and lacks systematicness.In this paper,several sets of comprehensive experimental projects,including thermal transition,physical aging,crystallinity measurement and compatibility characterization experiments are designed through the design and expansion of the original experiment content based on the application of DSC in the polymer physics experiments.The setting of the experiments can help students to understand the principle and method of DSC analysis,learn to apply the method to systematically study the molecular movement and transition of polymer,stimulate their enthusiasm for learning,and develop the ability to use relevant knowledge to analyze and solve practical problems.
