一、空间人体实验的必要性 空间人体实验就是以航天员作为被试者进行的实验。这种人体实验不仅代价昂贵、实验条件差（如被试者少、实验条件不宜控制、测量方法受限等），而且必然削减了其它航天实验项目。因此是否需要进行空间的人体实验必须进行认真的考虑。从目前的情况来看 First, the necessity of space human experiments space Human experiments is based on astronauts as subjects were experiments. Such human experiments are not only expensive, poor experimental conditions (such as less subjects, experimental conditions should not be controlled, measurement methods are limited, etc.), and will inevitably cut other space experiment project. Therefore, human experiments in space need to be carefully considered. From the current situation
