On the basis of the study of cadavers withe the technique of CT and DIP in this project, 50 youngmale cadavers were undergone investigations through scanning, image analysis, examnation andthe statistics. Thus, the accuracy and reliability of the inertial data includingl of the Chinese maleyoung bodies (the length, volume, mass and density of the segments of the body, et al.) wereabtained. Thus. the mass distribution of the Chinese male young bodies was determined. A series ofreliable data is then provided for establishing the model with inertial parameters of the Chinesehuman body and in addition a establishing means for study and analysis of the biomechanics ofhuman body is also furnished.
