摘要
本文基于生理学理论和实际数据,以身高H(t)、体重W(t)为基本量,建立了一个分段表示的一阶常微分方程组作为人体体重变化的数学模型,并对该模型进行了讨论。经检验,理论数据与实际数据吻合得很好,说明该模型较好地描述了人体体重变化的规律。
On the basis of theory of physiology and measured data, a system of
ordinary differential equation of first order is derived as the mathematical model for variation in human body weight, calculated values are found to be in good agreement with the measured ones.
