1.The burning rate under 7.0 MPa can be reduced to 6.87 mm/s with ratio 1:1:1 of burning rate modifiers glycerol triacetate/polyoxymethylene/sucrose octa-acetate.
2.The extracting ability of several organic solvents such as ethyl acetate, butyl acetate, glycerol triacetate, iso amy lacetate, and n butanol, was compared, and it was found that ethyl acetate was a good kind of organic solvent.
