摘　　要：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。The main differences between physiological effects of microgravity in spaceflight and simulated microgravity on humans appeared in the circulation of the low pressure side,in humoral and electrolyte metabolism. For a further understanding of the physiological effects of microgravity, some improvement of the current human experimental models are needed. It is possible to choose more adequate models closer to the situation in microgavity through measuring cardiovascular parameters, fluid regulation and renal excretion variables under head up tilt(HUT) plus lower body positive pressure condition, or under head down tilt(HDT) plus upper body negative pressure in various angles and pressure levels.
