对于美国国家航空航天局(NAsA)研究微重力对人体影响的科学家来说,重力是一个非常重要的影响因素。NASA约翰逊航天中心的科学家和发明家——Thomas J.Goodwin博士解释说:“微重力或无重力等外力作用可能会导致人体生理学的重大新发现,从而使人类受益。”生物反应器就是其中的一个案例。为了在实验室中复制微重力环境,NASA科学家发明了一种生物反应器——旋转壁容器(RwV),可使培养介质和细胞悬浮在设备的腔室内,模拟持续的 For scientists at NASA to study the effects of microgravity on the human body, gravity is a very important factor. Dr. Thomas J. Goodwin, a scientist and inventor at the NASA Johnson Space Center, explains: “Biomechanics, such as microgravity or gravity-free, can lead to major new discoveries in human physiology that benefit humans.” Bioreactors are One of these cases. In order to replicate the micro-gravity environment in the laboratory, NASA scientists have invented a bioreactor, a rotating wall container (RwV), to suspend culture media and cells in the chamber of a device to simulate a sustained
