本文目的旨在探究地面及太空飞行研究中影响机体能量利用和行为的生物化学变化的生理学资料。重点针对阿波罗月球探险、太空实验室扩展太空研究和航天飞机飞行过程中机体对能量的利用。有关飞行及卧床休息过程中的代谢将与胃肠道功能的研究资料一并讨论。人类太空飞行对能量的利用可通过膳食史、代谢平衡实验、食物的消耗量及呼吸气等几种方法间接确定。太空实验室的任务是对与代谢平衡研究密切相关的膳食进行记录。通过2种方法确定太空食品所提供的能量水平,即用弹式热量计直接测定和通过计算碳水化合物、蛋白质和脂肪的摄入量间接确定。用弹式热量计还可直接测定随粪便、尿等排泄的能量,根 The purpose of this paper is to explore physiological data on the biochemical changes affecting the energy use and behavior of the body in ground and space flight studies. Focus on the Apollo lunar expedition, Space Laboratory to expand space research and space shuttle flight energy use. Metabolism during flight and bed rest will be discussed along with research data on gastrointestinal function. The utilization of energy by human space flight can be indirectly determined by several methods, such as diet history, metabolic balance experiment, consumption of food and breathing gas. The mission of Space Labs is to document the diet that is closely related to metabolic balance studies. The energy levels provided by space food are determined in two ways, directly on the bomb calorimeter and indirectly through the calculation of carbohydrate, protein and fat intake. With the bomb calorimeter can also be directly measured with excrement, urine and other excretion of energy, roots
