地面模拟失重的实验方法综述

虽然载人航天事业已得到突破性的进展，但航天员对失重的适应和返回地球后的再适应，无论在理论上还是实践中都是尚未攻克的技术难题。航天失重环境下航天飞行综合征的发生机理及对抗措施，仍是航天医学的重要课题。在地面上无法创造长期的失重环境，但根据失重对机体产生的生理效应可实现地面模拟失重实验。本文概述了地面模拟失重的人体实验、动物实验概况，为更好开展地面模拟失重条件下相关研究提供参考。

The review of the ground-based simulation techniques on microgravity

Although the manned space flight has made great progress, but the problems that the astronauts adapt to weightlessness on the outerspace and the readjustment after their return to the earth, has not to conquer no matter in theory or in practice. The microgravity flight syndrome occurrence mechanism and the countermeasure remain an important task of aerospace medicine. Nowadays, it is unable to create long-term weightlessness environment on the ground, while we can realize the ground-based simulated weightlessness experiments according to the physiological effects of microgravity on the body. This paper summarizes the ground-based simulation techniques on microgravity in human and animals, in order to provide references on the researches of ground-based simulated microgravity.
