摘　　要：将人体运动系统视为一由 19个实体构成的刚性框架系统 ,每一实体上的父结点绕与上级实体连接的关节点旋转 ,该实体另一端的子结点则作为下一级实体的父结点。在每一实体中 ,由父结点指向子结点构成实体矢量 ,人体运动系统可将其分为 5条矢量链。采用矢量累加法 ,按矢量链的次序逐级算出每个实体矢量的父结点 ,构成人体运动姿态矢量框架。The human moving system is defined as a rigid frame, which contains 19 articulate entities. Entity rotates around the father node and its son node is the father of another entity at the next level. The human frame is divided into 5 entity links. Through the vector summation algorithm and along the link, each entity's father nodes are calculated successively, and the vectorial frame of human posture is constructed. With all the entity patterns pasted on the vectorial frame, the picture of human moving posture is drawn.
