人在头低位卧床时拟交感药物引起的心血管反应：食物中钠的作用心血管系统对微重力的适应过程中表现出交感肾上腺功能的变化和心血管功能失调。心血管功能的失调将引起航天员飞行后立位耐力降低。本实验的目的是比较吃正常食物和含高钠食物的两组被试者在卧床前、中、后服...
Cardiovascular Response to Sympathetic Drugs Induced by People in Bedridden Heads: The Role of Sodium in Food Cardiovascular systems show sympathetic changes in adrenal function and cardiovascular dysfunction during their adaptation to microgravity. Disorders in cardiovascular function will cause astronauts to lower their standing stamina after flight. The purpose of this experiment is to compare the two groups of subjects who eat normal food and high sodium foods in bed, in the ...
