研究了加热速率对燃烧合成热爆炸模式温度分布和反应产物均匀性的影响。使用简单的数学模型对温度曲线进行分析表明，在预燃烧期间消耗了很大一部分反应物，在反应物界面形成金属间化合物，这一点已通过实验得到证实。讨论了从温度曲线测量的参数与反应物转化为产物的程度之间的关系。
Effects of heating rate on the temperature profile of the thermal explosion mode of combustion synthesis and on the homogeneity of the reaction product are investigated. Analysis of the temperature profile using a simple mathematical model indicated that a significant fraction of reactants is consumed during the precombustion duration, forming intermetallic compounds at the reactant interface, which was confirmed experimentally. The relationship between the parameters measured from the temperature profile and the degree of conversion of reactants to products is discussed.
