| Abstract: | According the problem of the method of measuring the rigid body moments of inertia,advanced the relevant improved step.By the improved method,the initial angular velocity at uniformly retarded motion was interdicted,and the result could avoid being influenced by resisting moment according to the angular velocity,and the error was reduced. |

| Keywords: | resisting moment rigid body moment of inertia constant torque improved |
