计算中国男性人体环节惯性参数的数学模型及其三元回归方程的研究

STUDY OF MATHEMATICAL MODEL AND TRINAL REGRESSION EQUATION FOR CALCULATING INERTIAL PARAMETERS OF CHINESE YOUNG MALE BODIES

目的 :确定计算中国男性青年人体惯性参数的数学模型。方法 :采用CT 图像分析仪测算法 ,对 5 0例中国男性样本 (1 8～ 2 3岁 )进行了全身CT横断层扫描、影像分析和测算。结果 :设计了由 1 5个环节组成的中国男性青年人体数学模型 ,并据此建立了以身高、体重、坐高 /身高为自变量的直接计算中国男性青年人体惯性参数的三元回归方程。结论 :为直接计算中国男性青年人体整体及各环节的质量。

Objective:To set up a mathematical model to calculate the inertial parameters of the Chinese young male bodies.Methods:By using the CT DIP method in this projcct,for 50 young Chincse malc (18 23 yearold) received the scanning,image analysis and calculation.Results:Thus,we set up a 15 segments mathematical model of the Chinese young male bodies and a trinal regression equation that could immediately calculate the inertial parameters of segments of the young Chinese male bodies,in which the body weight,stature,and seat high/stature were acted as independent variablc quantity.Conclusion:A dependable method is established for the immediate calculating the mass and mass center of the segments and total body of the young Chinese male bodies.
