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.
