摘　　要：玻璃化转变温度是其重要的物理性能之一,其可以用于工业上产品性能的比较方法之一。为了了解环氧树脂不同测试方法下的玻璃化转变温度差异,本文采取差示扫描量热法(DSC)和热机械分析法(TMA)测试相同灯珠环氧树脂材料的玻璃化转变温度并比较之间的差异。The glass transition temperature was one of important physical properties,and it could be used as one of the comparison method of industrial product performance.In order to realize the differences in glass transition temperature of epoxy resin under different test methods,this article used the differential scanning calorimetry(DSC)method and thermal mechanical analyzer(TMA)method to test the glass transition temperature of the same lamp bead epoxy resin material and compare the differences.
