实验发现，FG是一种降低HTPB推进剂压强指数的高效添加剂。
The experiment indicates that FG is a good additive for reducing the pressure exponents.
结果表明：二茂铁衍生物（RMT）能大幅提高推进剂燃速和降低高压燃速压强指数。
The results show that ferrocene derivant (RMT) can effectively enhance burn rate of propellants and reduce its pressure exponent under high pressures;
当FG与亚铬酸铜组合使用时，可在提高推进剂燃速的同时大幅度地降低燃速压强指数。
When FG and YB are incorporated, they may obviously reduce the pressure exponent of HTPB propellant as well as enhancing the burning rate.
通过燃速测试，筛选的添加剂加入到低残渣燃气发生剂体系中能够拓宽燃速范围，同时也能降低压强指数。
The burning rate testing shows that the pressure exponent can be decreased, and the burning rate can be broaden by the selected additives entering into the gas generator propellant with low residents.
