摘　　要：分析了燃速催化剂和主要气体产物对燃速的高压差示扫描量热(PDSC)特征量关系方程参数的影响,结果表明,该方程的压强因子与压强指数线性相关,RDX-CMDB改性双基推进剂(R系列推进剂)的燃速催化剂影响燃热因子,主要分解气体产物相对量值比与"燃热因子"和"压强因子"有线性关系或有近线性关系。因此,该方程除了可以描述PDSC的特征量与燃速的关系外,还可以描述推进剂的催化剂作用,也可以定量描述气体产物提高燃速和降低压强因子或压强指数的作用,同时通过它还可揭示燃速催化剂的作用机理。The influence of burning catalysts and main gaseous products of decomposition on the parameters for pressure differential scanning calorimetry（PDSC） characteristics equation of the burning rate have been analyzed.The results show that the pressure factor m in the equation is correlated with pressure exponent and the ＂burning-heat factor＂ ku values of RDX-CMDB propellants（R series propellants） are affected by burning catalysts,and a linear correlation or an approximate linear correlation appears in between the relative concentrations of main gaseous products of decomposition and ku or m values.Therefore,It is considered that the equation can represent the correlation between PDSC characteristics and burning rate,besides,it can be also used to describe the effects of burning catalysts and to quantitatively describe the effects of gaseous products on the increase in burning rate and the decrease in pressure factor or pressure exponent.And,the active mechanism of burning catalyst could be also revealed by means of the PDSC characteristics equation.
