研究了由硝酸三乙二醇酯(TEGDN)、硝化甘油(NG)和硝化棉(NC)组成的火炮发射药的自加速分解温度(TSADT)、热爆炸临界温度(Tb)、绝热爆炸时间(TTIad)、50%撞击感度落差(H50)、撞击热点引爆临界温度(Tcr)、安全度(SD)、临界热爆炸环境温度(Tacr)和热爆炸概率(PTE)。该发射药的热安全性评价结果为：(1)T00=433.4 K，TSADT=TE0=441.1 K，Tb=Tbp0=468.4 K：(2)当Ek=205.3×103JmoL−1，AK=1020.62 S−1时，tTIad=48·3 S，H50=17·93 cm，Tcr，热点=634.9 K，球形样品TS(T)max=369.0K，Tacr=364.2 K，SD=65.03%，PTE=34.96%。
The self-accelerating decomposition temperature (TSADT), critical temperature of thermal explosion (Tb), adiabatic time to explosion (tTIad), 50% drop height of impact sensitivity (H50), critical temperature of hot spot initiation caused by impact (Tcr,hotspot), safety degree (Sd), critical thermal explosion ambient temperature (Tacr), and thermal explosion probability (PTE) of the gun propellant composed of triethyleneglycol dinitrate (TEGDN), nitroglycerin (NG), and nitrocellulose (NC) were studied. The results of thermal safety evaluation on the gun propellant were obtained: (1) T00 = 433.4 K, TSADT = Te0 = 441.1 K, Tb = Tbp0 = 468.4 K; (2) when Ek = 205.3 × 103 J mol −1 and Ak = 1020.62 s −1, tTIad = 48.3 s, H50 = 17.93 cm, Tcr, hotspot = 634.9 K; for a sphere sample, TS(T)max = 369.0K, Tacr = 364.2 K, Sd = 65.03%, PTE = 34.96%.
