摘要：
Cylindrical motors method was built to determine the poisson's ratios of solid propellants. According to the maximum radial deformations of the perforations of cylindrical motors with two different outer-inner radial ratios after having been cured and dropped in the temperatures, the poisson's ratios of the solid propellant grain at the different temperature was fit out by use of FEM. The relative errors of the poisson's ratios determination at different temperature don't exceed 0.5%.
