摘　　要：为研究云爆剂中硝酸异丙酯渗露对双基推进剂的热分解性能影响,采用加速量热仪(ARC)对双基推进剂在加入硝酸异丙酯环境下的热分解情况进行测试,得到其绝热分解的温度、压力时间曲线,利用速率常数法计算出样品的活化能和指前因子等动力学参数。研究发现在加入硝酸异丙酯后,双基推进剂的起始热分解温度升高,表观活化能变大,表明硝酸异丙酯会提高双基推进剂的热稳定性。The objective of this paper is to study the effect of leaked isopropyl nitrate （IPN） in fuel air explosive leaked on the thermal decomposition characteristics of biradieal propellant. First, the thermal decomposition of IPN-added biradieal propellant is tested with accelerating rate calorimeter （ARC） to get corresponding temperature-time and pressure-time curves and activation energy and pre-exponential factors as well as other kinetic parameters are obtained through speed constant algorithm. The initial exothermal temperature and the apparent activation energy of the biradical propellant are observed increasing after the IPN is added, suggesting that IPN can make the biradical propellant more stable.
