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。
The catalytic effect of lanthanum (cerium) / copper salt, lanthanum / lead salt, lanthanum / cerium composition and lanthanum / cerium roasting composite on the combustion of double base propellant was studied. It was found that the improvement of catalysis of copper salt on the platform of rare earth compound , Lead salt moves the catalytic range of rare earth compounds to the high pressure zone. The catalytic combustion of lanthanum / cerium group (complex) is closely related to the ratio of lanthanum / cerium, and more than two platform combustion zones are generated in the double-base propellant. Rare earth / copper salts contribute more to the infrared transmission of double-base propellants than other binary rare earth compositions.
