摘　　要：利用补偿法证明了半太极图形状的均质薄板在以完整太极图中心为坐标原点的任意坐标系中的轴转动惯量和惯量积保持不变的性质,讨论了带电粒子在匀强磁场的半太极图形区域中运动的特殊性质,以此二例展示了太极图所蕴含的物理美.In order to complete the moment of inertia and product of inertia properties of the plot remaining fixed for any of the center of the coordinate origin of the coordinate system axis,the compensation method is used to prove uniform rigid sheet showing the shape of a half Tai Chi diagram. The special nature of the graphics area semi- Tai Chi movement of charged particles in a uniform magnetic field is discussed. The latter shows the Tai Chi diagram inherent physical beauty.
