体反応は、これまで、地上の１Ｇ環境におかれた小動物
をスペースシャトルに積み、宇宙の約１０-4Ｇの環境に
約１〜２週間おいて、いわゆる宇宙実験を行っている。2. Description of the Related Art A biological reaction of a small animal in a gravitational step reduction field has hitherto been carried out by loading a small animal placed in a 1G environment on the ground on a space shuttle for about 1 to 2 weeks in an environment of about 10 -4 G in space. And so-called space experiments are being conducted.

【発明が解決しようとする課題】しかし、上記の宇宙実
験には次のような短所がある。 通常では１Ｇ→１０-4Ｇの重力変化しか起こせない。 重力減少後の実験期間が１〜２週間しかなく、十分な
変化を観察することができない。 シャトルのフライト機会が少なく（２年に１回程度）
データを蓄積することが難しい。 計画を立ててから実験を行うまでの期間（数カ月から
数年）を要する。 実験装置（飼育箱など）が宇宙仕様となるため非常に
高価になる。 宇宙実験では、搭乗科学者一人に対して実験テーマが
２０〜３０件と多いため、詳細な観察を期待することが
できず、現象を見落としたり、操作不十分になる恐れが
ある。However, the above space experiment has the following disadvantages. Normally, only 1G → 10 -4 G gravity change can occur. Since the experimental period after gravity reduction is only 1 to 2 weeks, sufficient changes cannot be observed. Fewer shuttle flight opportunities (about once every two years)
It is difficult to store data. It takes a period (a few months to a few years) from making a plan to conducting an experiment. It becomes very expensive because the experimental equipment (such as breeding boxes) has space specifications. In space experiments, since there are many experiment themes of 20 to 30 for one boarding scientist, detailed observation cannot be expected, and there is a risk of overlooking the phenomenon or insufficient operation.

It is intended to provide an experimental method and an apparatus for the same that easily form a gravitational step reduction field on the ground and make it possible to investigate the biological reaction of small animals.
