摘要： 论述丁羟平台推进剂研究结果,使用新型燃速添加剂EM₅₀₃和组合添加剂EMT,可使燃速为7mm/s,5mm/s左右的丁羟推进剂得到良好的平台效应,本文还对平台效应的机理作了简略分析和讨论。

Abstract: By using new type of burning rate additives EM503 or combined additives EMT the burning rate pressure exponent reduces from 0.4 to about 0.1 for the HTPB propellant with burning rate no greater than 8 mm/s. The plateau effect is observed. The mechanism of the plateau effect is also analysed and discussed abbreviatively in this paper.
