摘　　要：采用DSC和红外测试技术研究了环氧树脂与1,8-间萘二胺的固化过程。结果表明,反应的理论凝胶温度Ti为360.33K、固化温度Tp为391.79K、后固化温度Tf为413.05K;并由Kissinger和Ozawa方法分别求得固化反应的表观活化能ΔE为67.166和70.379kJ/mol,依据Crane理论得到固化反应级数为n=1.00。The epoxy resin/1,8-diaminonaphthalene curing system was studied by DSC and Fourier transform infrared spectrometry（FT-IR）. The results show the gel temperature Ti （360. 33 K）, curing temperature Tp （391.79 K） and completeness curing temperature Tf（413.05 K） was determined by DSC. Via the Kissinger and Ozawa methods, the apparent energy of activation（AE） was 67. 166 kJ/mol and 70. 379 kJ/mol respectively, the reaction order（ n = 1 ） was calculated according to Crane theory.
