为了评价人体能量消耗构成比,本文描述了构建人体能量消耗的三大营养素构成比数学模型的推演过程.总氧消耗、总二氧化碳排出和总氮(尿氮+皮肤氮)排出与三大营养素的氧化有关,并且这三种营养素的生理燃烧值是已知的.基于这些可测定的和已知的参数,我们构建的数学模型有助于了解受试个体的能量消耗特点.

In order to assess the constituent ratios of energy expenditure in human, the deductive process of establishing a mathematical model for assessing the constituent ratios of the three major nutrients in energy expenditure in human was described in this paper. Total oxygen consumption, total carbon dioxide output and total nitrogen (urine nitrogen + skin nitrogen) excretion are related to the oxidation of the three major nutrients and the physiological combustion values of the three nutrients are already known. Based on these measurable and known parameters, the mathematical model established by the authors will help understand the characteristics of the tested individual's energy expenditure.
