The nitroguanidine is added to the propellant during its mixing phase.
在推进剂的混合阶段将硝基胍加到推进剂中。
The thermal decomposition of single, double-and triple-base nitroguanidine propellants was studied by differential scanning calorimetry (DSC).
用差示扫描量热计（DSC）研究了单基、双基和三基药热分解性能。
The results show that irradiation of the poor uranium alloy had no remarkable influence on the burning properties of three-combination nitroguanidine propellant.
