摘　　要：用PDSC和TG-DTG研究了RDX-CMDB改性双基推进剂在一种含能复合燃速催化剂作用下的热分解。与对燃速的影响相似,复合燃速催化剂中不同成分的组合对PDSC各特征量有不同的影响。在RDX-CMDB改性推进剂的PDSC试验中获得的放热速率特征量和压强的平方根与燃速能用一线性方程关联。获得的"燃速与PDSC特征量相关因子"能用以研究燃速催化剂的作用。The thermal decompositions of RDX-CMDB modified double base propellants with a composite burning catalyst were investigated by using of PDSC and TG-DTG. It is shown that the influence of the burning catalysts with different components on the characteristic values of PDSC is different in the decompositions of RDX-CMDB, Which is similar to the catalyst on burning rate. The characteristic values, which are the square roots of heat release rate and pressures on PDSC tests, can be correlated to burning rates of RDX-CMDB by using a liner equation. The ku, correlation factor of burning rate with PDSC characteristic value, can be used to study the effect of burning catalysts on burning rate of the propellants.
