摘　　要：采用差示扫描量热(DSC)法、热重-微商热重(TG-DTG)以及恒温热失重(ITG)法,对含磷瞬时发烟剂进行相容性机理研究。由结果可知,其主要成分硝酸胍与赤磷混合后存在强烈的相互作用,分解放出大量气体产物,造成其混合体系不相容;但在加入氧化剂ZnO后,体系在200℃前的相互作用微弱,使混合体系相容。ITG动力学结果同样得出:不同混合体系的不同相互作用,可以以机理函数和反应速率的大小作比较。The compatibility mechanism of transient smoke agent containing phosphorus is researched by differential scanning calorimetry, thermogravimetry-derivative thermogravimetry and isothermal mass loss method. The mixed system of red phosphorus and guanidine nitrate is completely incompatible, and there is a intense reaction with releasing gas product. If the oxidant（ZnO） is added in, the mixed system is compatibile ,and the reaction is very weak when temperature is below 200℃. The kinetic result of ITG indicates that the different interaction of different mixed system can be compared by the thermal decomposition mechanism function and the reaction rate.
