    西媒:科學家研制出仿造重力裝置 向人工重力邁進一步

    2019-07-04 06:38:01 參考消息網

    參考消息網7月4日報道 西媒稱,科學家研制出一個將能在宇宙飛船和空間站中仿造重力的樣品裝置,這將幫助宇航員保持健康。

    據埃菲社7月2日報道,美國科羅拉多大學博爾德分校的實驗室向著在科幻電影中才能看到的人工重力又邁進了一步。這里的研究人員希望在不久的將來,使在宇宙飛船和空間站中制造人工重力成為現實。

    該校2日發表聲明表示,由研究員托林·克拉克領導的研究團隊研制出一個將能在宇宙飛船和空間站中仿造重力的樣品裝置,這將幫助宇航員保持健康。

    克拉克在該聲明中說,在太空中,宇航員的骨密度和肌肉量都會降低,他們的心血管系統功能會減弱,他們的健康還會受到其他影響。截至目前,用于解決這些問題的只有一些相互不連貫的對策。

    報道稱,這項新技術將使人類得以抵擋失重造成的負面影響,這將延長人類能在地球以外停留的時間,并進而使宇航員到達更遙遠的地方。

    其方法是在太空站建設配置人工重力的“房間”,宇航員每天在其中度過一段時間,以接收每日定量的重力。克拉克說,這就像是通過做水療對抗失重一樣。

    該研究團隊研制的樣品裝置是一個放在半徑不大的離心機上的金屬平臺,外形像是醫院所用的擔架。離心機的轉動速度可變。

    克拉克承認,該裝置與游樂園里的轉盤游戲設備的相似之處顯而易見。但游樂園里的轉盤會讓人感到眩暈并失去方向感,而該裝置不會產生那些效果,并且已經有成功使人體適應人工重力作用的案例。

    研究人員發現,志愿者在使用該裝置大約10次后就不再有身體下墜的錯覺。

    參與此項研究的研究生凱瑟琳·布雷特爾說:“我們工作的重點是嘗試讓更多人認識到人工重力不是瘋言瘋語,也許它在科幻作品之外也有一席之地。”(編譯/蘇佳維)
