| Abstract: | We calculated the moment of inertia while axes of rigid-body wasn＇t coincide with instruments based on the columniform rigid-body. The conclusion can be used to uniform thin stick and disc by proximate way. And the concludes was discussed, which can be used to improve the measure method and promote the practice application. |
