【摘要】 目的测算并确定中国男性青年人体惯性参数及其数学模型,建立计算中国男性青年人体体段转动惯量的多元回归方程。方法采用CT—图像分析仪测算法,对50例中国男性样本(18～23岁)进行体态参数测定、全身CT横断层扫描、影像分析、测算,并进行逐步回归分析。结果获得了50例中国男性青年人体样本各体段转动惯量数据,设计了由15个体段组成的中国男性青年人体数学模型,并据此推导、建立了以身高,体重,体段长度、宽度、围度等为自变量的直接计算中国男性青年人体转动惯量的多元回归方程。结论为直接从个体的体态参数来推算人体各体段的转动惯量参数提供了可靠的手段。更多还原

【Abstract】 Objective To set up the multiple regression equation that could immediately calculate the segmental move inertia of the Chinese young male bodies by determining the data of move inertia of the segments and the mathematical model. Methods By using the CT-DIP method in this project , to carry out the determination for 50 Chinese young male living subjects (18～23 year-old) on their posture parameters , the scanning , image analysis , calculation , and progressive regression so that to choose and define the important variable quantities. Results A series of the data on move inertia of the segments were obtained and set up the mathematical model consisted of 15-segments. The multiple regression equation was then established which could immediately calculate the move inertia of the segments of the Chinese young male bodies, in which the body weight , the stature , and the segmental length , the wide, and the contour were usedas independent variable quantity. Conclusion This study provided the dependable means to calculate immediately the move inertia of the segments of the Chinese young male bodies .更多还原
