如果你可以隐身一天,你最想做什么?
If you could be invisible for one day, what would you do?
在一些科幻、魔幻小说中所讲到的不被他人所用肉眼看到的一种存在状态。又分为实体隐身和虚体隐身。实体隐身是指纯粹意义上的隐身,如当你隐身时别人可以从你的身上穿过而没有察觉;虚体隐身是指仅仅他人用肉眼看不到你,但是可以感受到你(如触摸到你)。
In countless fantasy or science fiction plots, invisibility is the state of an object which cannot be seen by the eyes. It can be divided into two sections: actual invisibility and virtual invisibility. The former one refers to invisibility in the pure sense, as in this state, other people can go through your body without any notice. The latter one refers to invisibility that you are invisible by sight, but can be felt or touched by others.
据美国媒体报道,科学家开发出全球首件二维“隐身衣”。美英两国科学家利用光学原理,成功地用它“隐身”了一个铜圆柱体。这一重大发现已被刊登在《科学》杂志上。
According to American media report, scientists have successfully developed the world’s first two-dimensional invisibility cloak in the world. Utilizing the optical principle, scientists succeeded in cloaking a copper cylinder by it. This discovery has been published in the Science Magazine.
据报道,这件“隐身衣”主要材料为金属和电路板材料的混合物,比如陶瓷或光纤合成物等等。这种材料吸收了特定的光线,人的肉眼是感受不到比较微弱的光线,就好像物体不存在一样。
It is reported that the “invisibility cloak” is made of mixtures of metal and circuit board materials such as ceramic or fiber composite. Since particular light spectrum is absorbed by this material, the remain light is so weak that it cannot be felt by human eyes, then object itself disappears from view as if it doesn’t exist.
