摘　　要：系统地介绍了复合固体推进剂玻璃转化温度（Ｔｇ）测试的几种表征方法，并评估了各方法的优缺点。通过动态效机械分析（ＤＭＡ）获得的推进剂参数曲线可以看出，用损耗模量Ｅ″的曲线表征Ｔｇ，比较合适。The measurement methods of the glass transition temperature for composite solid propellants are presented and evaluated. Through observing the performance curves of solid propellant obtained by means of dynamic mechanical (thermal) analysis (DMA or DMTA), it seems that the loss modulus E' curve is move suitable for charactering Tg.
