航天和模拟微重力时研究表明 :微重力与现有模拟微重力模型时人体生理学变化的主要差异表现在低压区循环和体液、电解质代谢。微重力生理研究的人体模型在进一步了解微重力对人体的生理影响和机理中不可缺少 ,有必要将现有人体模拟微重力模型加以改进。利用人体不同角度和不同压力制度的立位倾斜 (HUT)加下体正压、头低位卧床 (HDT)加上体负压 ,测量心血管参数、体液调节因子、肾排泄的有关指标 ,与航天中的相应指标对照 ,筛选出更接近于微重力状态的人体模拟微重力模型 ,使其具有一定的可行性。
Aerospace and simulated microgravity studies show that the main differences in human physiology between microgravity and the existing simulated microgravity model are the cycling of the low pressure zone and the metabolism of body fluids and electrolytes. The human body model of microgravity physiological research is indispensable in further understanding the physiological effects and mechanism of microgravity on the human body. It is necessary to improve the current human simulated microgravity model. Using HUT plus body pressure, head-lying bed rest (HDT) plus body negative pressure, measurement of cardiovascular parameters, humoral regulatory factors, and renal excretion using different angles and pressures of human body, Compared with the corresponding indicators, the human simulated microgravity model closer to the state of microgravity was screened to make it have a certain feasibility.
