如何在地球表面模拟空间微重力环境或效应：从空间细胞生长对微重力响应谈起

How to stimulate a space microgravity environment or effect on Earth: From the viewpoint of responses of space cell growth to microgravity

当前,人们对空间微重力环境影响生命、化学、物理等过程的认识仍较为粗浅,在地球表面是否可以且如何模拟空间微重力环境或效应尚不清楚.本文拟从空间细胞生长对微重力响应这一基本问题入手,从力学/物理基本原理出发,讨论什么是重力变化、如何模拟微重力环境或效应、怎样模拟微重力环境所致的生物学响应等问题,以期澄清空间生命科学与空间生物技术、乃至空间生理学与医学研究中的相关基本概念,为地基相关研究提供科学参考.

Little is known about the effects of a microgravity environment in space on biological, chemical, and physical processes. It also remains unclear if it is possible to simulate a space microgravity environment or effect on Earth. This paper discusses, according to the mechanical/physical principles of the basic processes of cell growth in space, the issues of what gravitational change is, how a space microgravity environment or effectcan be simulated, and how biological responses to a simulated microgravity environment can be mimicked. It aims to elucidate relevant concepts in space life science and biotechnology, as well as in space physiology and medicine, and to present the scientific merits of related ground-based investigations.
