摘　　要：目前已有专家学者用欧拉角来描述髋关节的运动 ,然而 ,欧拉角的运用会出现数学计算上的困难 ,且所涉及的转轴与人体基本运动轴不一致。本文介绍与人体运动轴较为相符 ,又可避免数学计算困难的一种描述人体下肢环节空间运动简化的方法 ,即用布里恩角描述下肢环节的定点运动。Euler angle is currently used to describe hip joint motion of the human body by some experts and scholars,but the difficulty in mathmatical calculation will arise from the application of it,and the rotational axis dealed with will be different from the elementary movement axis of the body.A new method,that is,describing the fixed-point motion of lower limb taches with Bryant angle,which can bring the rotational axis into correspondence with the movement axis of the body and avoid what will arise from the application of Euler angle to the description,has been introduced in this paper.

关 键 词：刚体方位广义坐标 环节独立坐标系 布里恩角 欧拉角 标准解剖姿势 环节运动基准位
