When FG and YB are incorporated, they may obviously reduce the pressure exponent of HTPB propellant as well as enhancing the burningrate.
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。

The results of the burningrate measurement showed that the nanometer sized lead oxide can play a role in decreasing the pressure exponent of NEPE propellant.
Effect of some inorganic lead salt and aluminium oxide on burningrate pressure exponent and temperature sensitive coefficient of polyurethane composite solid propellant have been investigated.
