摘要
讨论了质点系对任意点的动量矩定理。从潘索定理出发推导了刚体的转动瞬心的加速度,在此基础上得出了刚体对瞬心的动量矩定理与对固定点的动量矩定理在形式上相同所必须满足的条件。
This article discusses the theorem of moment of momentum for an optional point about a group of particles, and inferres from poinsot theorem the acceleration of instantaneous turning centre of a rigid body, and on the foundatious reaches a condition witch must be provided if the theorem of moment of momentum for instantaneous turning ceutre of rigid body is similiar to the theorem of moment of momentum for static point in form.
