摘　　要：根据质点动能定理的推导过程，评述功的定义式中的位移应是力所作用的质点的位移。According to the deducing process of the theorem of kinetic energy for a particle,it can be concluded that the displacement in the definition formula of work should be that of particle which force works on,and another form about the definition formula of work is put forward.

关 键 词：动能定理 位移 功
