中国女性青年人体惯性参数的CT—图像分析法测定及其回归方程的研究

采用CT成像和图像分析技术，在尸体研究的基础上，对50例女性样本（18～23岁）进行全身CT横断层扫描、图像分析和测算以及建立数学模型等方面的研究。获得了人体的质量分布、质心位置和转动惯量等惯性参数。据此，建立了直接计算中国女性青年人体各环节惯性参数的二元回归方程。为中国人体运动学和动力学研究提供了基础数据；也为运动员的选材提供了有力的手段。

DETERMINATION OF INERTIAL PARAMETERS OF SEGMENTS OF CHINESE FEMALE YOUNG BODYS WITH CT-DIP METHOD AND ESTABLISHMENT OF ITS QUADRTIC COUNTING EQUATION

On the basis of the study of the corpse samples, taking advantage of the technique of CT and DIP in this paper, 50 young female bodys were made investigations going through the scanning, image analysis,examination,statistics, the establishing mathematic model of the human body. Thus, the accuracy and reliability of the inertial data of the Chinese female young bodys (for example, the average value of the mass distribution, the mass center and the move inertia, et al.) was obtained leadinglly in our country. The quadratic circular equation that calculated immediately the inertial parameters of segments of the Chinese female young bodys was set up. It supplied the basic data for the descussion about the motionology and impelusology of the Chinese human bodys primarily and also provided a powerful means for the motive image analysis and the select athletes.
