| 摘 要： | 在引入人体运动环节的概念和增补重量矩参数的基础上，利用二维平衡板推导了运动环节重心与人体总重心之间的联动关系，从而提出了人体总重心圆原理为了计算人体运动环节的重量矩，探讨了利用二维平衡板测量人体总重心圆半径的方法，并指出人体总重心圆原理的缺陷和实际测量时应注意运动环节移动幅度不宜太大等问题，以减少测量误差。

| Abstract: | On the basis of introducing the concept of body motion segment and subjoining the parameters of moment of gravity, the present study has used a two-dimensional balance board to deduce the linkage relationship between the centre of gravity of motion segment and general centre of body weight, and consequently put forward the principle of the circle of general centre of body weight. In order to calculate the moment of gravity of body motion segment, the study has made an approach of the method of using a two-dimension balance board to measure the radius of the circle of general centre of body weight, and pointed out the defect of the principle of the circle of general centre of body weight and some problems such as that the moving range of body motion segment should be paid attention to being not advisable to be too big while making concrete measurement, so as to reduce the measuring error, and so on. |
