Safety assessment of sodium azide and its mixtures with oxidizing agents, which are a gas generating chemicals for air bags, was carried out by thermal analysis, combustion calorimetry and burning rate measurement and the followingresults wereobtained.(1) Effect of some factors on the thermal reactivity of sodium azodeThe effect of particle size, crystallinity, atmosphere, moisture and aging on the thermal reaction of sodium azide was studied and the results were published in the related jurnal(Thermal analysis of sodium azide : Jurnal of Hazardous Materials, in press), Mechanochemistry of sodium azide was also studied and he resaults were published (Mechnochemistry of sodium azide : J.Explosie society of JAPAN, Vol.55, 4(1994)).The isothermal decomposition of sodium azide and its mixture with oxidizing agents was studied, and the rate equation and kinetic parameters for decomposition were obtained.

通过热分析、燃烧量热法和燃速测定等方法对叠氮化钠及其与氧化剂的混合物进行了安全性评价，得到了以下结果：(1)某些因素对叠氮化钠热反应性的影响研究了粒度、结晶度、大气、水分和老化对叠氮化钠热反应的影响，结果发表在相关期刊(叠氮化钠的热分析：危险材料学报，出版社)上，并对叠氮化钠的机械化学进行了研究，结果发表在《叠氮化钠的机械化学》，《日本爆炸学会杂志》第55卷，第55期。研究了叠氮化钠及其与氧化剂混合物的等温分解，得到了分解的速率方程和动力学参数。
