n.微重力

Once, President George H.W.Bush's science adviser was asked about the benefits of doing experiments in weightlessness and microgravity. 過去，老布什總統(tǒng)的科學顧問曾問起在無重力或微重力環(huán)境下進行科學實驗的收益。

Fluid is transferred cephalad in microgravity and simulated microgravity,and the pulmonary circulation is the first to be affected. 微重力或模擬微重力時體液頭向轉(zhuǎn)移，首先波及肺循環(huán)。
