| 摘 要： | 研究了镧（铈）／铜盐、镧／铅盐、镧／铈组合物及镧／铈焙烧复合物对双基推进剂燃烧的催化作用，发现铜盐对稀土化合物的平台催化作用的改善有利，铅盐使稀土化合物的平台催化范围向高压区移动。镧／铈组（复）合物的燃烧催化作用与镧／铈比例密切相关，且使双基推进剂产生2个以上的平台燃烧区。稀土／铜盐对双基推进剂红外透过率的贡献高于其它二元稀土组合物。

| Abstract: | The effects of binary mixtures composed of lanthanum (cerium) /copper salts,lanthanum/lead salts, lanthanum/cerium and binary composition of lanthanum/cerium prepared by baking on the combustion of DB propellants are studied. The resluts show that lanthanum/copper salts are advantageous to improve the plateau combustion of DB propellants, and lanthanum/lead salts remove the plateau combustion to the high pressure range. The combustion catalysis of lanthanum/cerium binary mixture (or composition) on DB propellants is related to the ratio of lanthanum/cerium and the binary mixtures (or composition) of La/Ce enable DB propellants to bring about more than two plateau combustion area. |
