摘要： 用“高低压声发射燃速测试系统”研究测定了特低燃速丁羟推进剂（ｒ＝２ｍｍ／ｓ～４ｍｍ／ｓ）在２ＭＰａ低压下的燃速和２ＭＰａ～１４ＭＰａ范围内的燃速压强指数。结果表明，特低燃速的测试精度可达１％，某ＨＴＰＢ－ＡＰ－Ａｌ－Ｔ２９－ＨＭＸ推进剂的燃速测试临界压强为２ＭＰａ。

Abstract: The measurement accuracy of burning rate at 2MPa low pressure and the burning rate pressure exponent at the range of 2MPa~14MPa for lower burning rate HTPB propellant(r=2mm/s~4mm/s)are studied using a burning rate measurement system at high and low pressure by means of acoustic emissionThe obtained results show that the measurement accuracy of lower burning rate can be within 1% and the critical pressure of burning rate measurement for HTPB AP Al T29 HMX propellant is 2MPa
