摘要
为了检查被试者对失重的适应能力,本实验采用了4h 头低位15°卧床方法模拟失重,观察了38名被试者在卧床中的耐受时间和脑阻抗图(REG)的变化,结果是短时间的头低位卧床期间REG 发生了规律性的变化,此变化反映了被试者脑循环系统状态,并与被试者卧床耐力一致。结果提示,短期头低位卧床可作为检查被试者失重适应能力的一种方法,而REG 是一个有用的评定指标。
In order to examine the adaptive capacity of humanbody for
bearing weightlessness (WL),the 4h head-down 15° bed-rest was used to
simulate WL.The tolerance time and the changes of REG during bed-rest
for 38 subjects were observed.The result is that the regular changes of
REG which reflect the state of brain circulation are found during the tes-
ting and it associated with the subjects' tolerance time.The results indicated
that the method of short time head-down bed-rest is an effective approach
to examine the adaptive capacity of subjects for bearing WL and the REG
is a valuable index.
