The discussion has served to emphasize the important role the inertia tensor plays in the discussion of the motion of rigid bodies . 讨论强调了惯性张量在论述刚体运动时所起的重要作用。
3.
The use of inertia dyadics enables one to deal with certain topics involving inertia vector and inertia scalars in a basis-independent way . 在处理包含惯性矢量和惯性标量的某些问题时，应用惯性张量则可作到与基无关。
4.
Next we set some other properties of the body : mass and the inertia tensor 下一步我们设置物体的一些其它属性：质量和惯性张量。
