摘　　要：系统地梳理了质点系的多种动能定理,包括(总)动能定理、质心动能定理和相对动能定理,并以质点系角动量定理的分解作为对比.然后,对一道柔链题进行了讨论.Multiple kinetic energy theorems are clarified systematically,including(total)kinetic energy theorem,barycentric kinetic energy theorem and relative kinetic energy theorem.One solution to a chain-problem is also discussed.

关 键 词：柯尼希定理 质心动能定理 相对动能定理
