| 摘要肥胖和超重是罹患非传染性疾病的重大风险因素，如心血管疾病，糖尿病，肌肉骨骼疾患等，并且使身材走形，影响美观和自信心。究其根本原因，是人体摄入的能量与消耗的能量之间的不平衡。我们将会运用微分方程和线性方程组结合其它医学、生物学等方面的知识，刻画、描述并最终对此问题建立控制饮食和运动健康减肥的数学模型.使用生物电抗法体脂率评测法来衡量和判定人体胖瘦程度的重要指标，并结合人体体脂率来确定适宜体重，通过对实际问题的数据测量，构造数学模型，制定最合理科学的减肥方案，以达到健康减肥保持体形的目的。50096 毕业论文关键词 体脂率 数学建模 微分方程 线性方程组 控制饮食与运动 Title Mathematical problems of biological size Abstract Obesity and overweight are suffering from significant risk factors of non communicable diseases, such as cardiovascular disease, diabetes, musculoskeletadisorders. And it makes out of shape and affects the appearance and self-confidence. The fundamental reason is human intake of calories consumed caloriesof energy imbalance. Differential equation and linear equation group withother medicine, biology knowledge in this paper.We can use characterizationto describing and then this problem in the establishment of a mathematicalmodel of the controlled diet and exercise health to lose weight. As a measureand an important index, Body fat rate can evaluate the level of body fat orthin. According to the measurement, mathematical modeling, the data of thepractical problems can determine the appropriate weight combined with the body fat rate. The results of the model are to explain the development of the most reasonable scientific weight loss programs, in order to achieve the purpose of healthy weight loss to maintain the body.
