险境求生之坠落的电梯

Q. If I find myself in a free-falling elevator, is there any position that might increase my chance of survival? (Climbing on top of other people is not an acceptable answer.)

问：如果你发现自己正在坠落的电梯里，是否有一种好的“体位”让我们获得更大的生存机会呢？（另，爬上别人的头并不是一个可以接受的回答。）

A. The best option would be to lie on your back on the floor as flat as possible, said Eliot H. Frank, a research engineer at the Center for Biomedical Engineering at the Massachusetts Institute of Technology.

答：最好的选择可能是让你尽可能地背朝下平躺在地板上，麻省理工学院生物医学工程学中心的研究工程师，艾略特·H·弗兰克如是说。“This will distribute the force of impact over the greatest area of your body so that no particular part of your body is subjected to the weight of any other part of your body,” he said.

“这种方式将分散对身体重要部位的冲击力，因此没有特定的身体部位承受其他部位的重量，”他说。“The impact of the elevator at the bottom of the shaft would subject you to extreme gravitational acceleration, or G-forces,” Dr. Frank explained. “The number of G’s you experience multiplies your normal weight, so if you experience 10 G’s, you would experience 10 times the weight of your body.

“ 这种处在电梯接近地面的冲击力将让你承受巨大的重力加速度，或者称重力，”弗兰克博士解释道，“以数量来衡你所体验到的重力将是你平时体重的数倍，如果你体验到了10倍重力，就相当于十个自己压在你的身上。“You might think that bracing yourself or bending your legs would help, but at high G-forces, your legs would simply not be able to support the weight of your body,” he said. “Even the weight of your own head would be too much for your neck to support.”

“你可能觉得挺直身子或弯曲你的脚可能会有用，但是在高倍重力下，你单单靠腿是不能够支撑你的重量，”他说，“甚至你的脖子也难以支撑头的重量。”The folk wisdom of jumping up at the moment of impact is convincingly debunked in a“MythBusters” video on the Discovery Channel Web site. It would not work unless you could know the precise moment of impact and leap at the same speed the elevator is plunging.

那种在电梯要撞击地面时就跳起来的土方法也被探索频道网站上一个“流言终结者”视频所完美终结。除非你能知道撞击的精准时机并且你跳的速度与当时的电梯速度一样，这个土方法将完全不起作用。Readers may submit questions by mail to Question, Science Times, The New York Times, 620 Eighth Avenue, New York, N.Y. 10018, or by e-mail to question@nytimes.com.
