寻求可替代TNT用于熔铸炸药的液相载体，在50～150℃范围内，用差示扫描量热仪研究了不同气氛（静态和N2）、不同加热速率（5，10，20，30℃? min-1）下甲基硝基胍（MeNQ）基低共熔物的熔融过程。研究了RDX、HNS对MeNQ基低共熔物熔融过程的影响。结果表明，随着升温速率的增加，熔融反应开始时间和峰温有相应的延迟，而熔化速率增加；添加RDX、HNS不能促进MeNQ基低共熔物的熔融；MeNQ基低共熔物的熔融过程符合1/2级反应动力学，升温速率为10℃? min-1时，MeNQ基低共熔物熔融反应的表观活化能为11．77 kJ? mol-1。

In order to obtain a potential TNT replacement for melt-cast explosives, the melting process of eutectic based on methyl-nitroguanidine (MeNQ) was studied by differential scanning calorimetry at 50~150 ℃ under different atmosphere (static state and N2 ) and heating rates (5, 10, 20, 30℃? min-1 ).Effects of HNS and HMX on the behaviors of melting of the eutectic were studied.Results show that with the increasing of heating rate, the time of melting and peak temperature of the sample delayed, while the rate of melting increases.HNS and HMX can not accelerate the melting of the eutectic.The melting rate of eutectic based on MeNQ follows the 1/2 order kinetics reaction, and the apparent activation energy of the melting reaction is 11.77 kJ? mol-1 at 10 ℃? min-1 .
