本文提出质点系相对动点的绝对动量矩和相对动量矩概念,导出普遍适应的两个定理,讨论了刚体作平面运动时瞬心动量矩定理,以及对动点求转动方程的条件。
In this paper, the concept of absolute moment of momentum and relative moment of momentum of relative moving point of particle system is proposed. Two universally applicable theorems are deduced. The moment of inertia moment theorem of rigid body is discussed.
