在北京西郊,有一座中国的宇航员培训基地,也是世界上第3座大规模的航天城。航天城有最快1分钟转24圈的转椅。这四面封闭、一张类似牙科治疗椅的转椅不但可以做180度顺时针和逆时针的快速运转,而且可以同时上下前后摆动。转椅主要用于检查宇航候选者的前庭神经功能,以了解其对震动及眩晕的耐受能力。 In the western suburbs of Beijing, there is a Chinese astronaut training base, which is also the third large-scale space city in the world. Aerospace City has the fastest 1 minute turn 24 laps swivel chair. The four sides are closed. A swivel chair similar to a dental chair can not only make 180-degree clockwise and counterclockwise rapid operation, but also swing back and forth at the same time. Swivel chair is mainly used to check the vestibular nerve function of aerospace candidates to understand their ability to withstand vibration and dizziness.
