If we have a solid cylinder, then the moment of inertia about this axis Q through the center of mass, which I've called Q, equals 1/2 MR squared.
假如有一个实心圆柱体，轴心的时间惯量,通过这个物质的中心，等于1/2，MR的平方。

We got three times the moment of inertia about the center.
也就是，关于中心处转动惯量的3倍。

Meanwhile, under two-group instability modes, it is discovered that the curves between electric power of generator unit and rotator's angle in relative to center of inertia is a sine curve.
