China’s Invisibility Cloak【21 Century(November 1, 2023)】 In the future, everybody will have a Harry Potter invisibility cloak in the closet, said Chu Junhao, academician of the Chinese Academy of Sciences in Shanghai on Saturday. At the Super Science Night 1. (hold) by Bilibili, China's major video-sharing platform, Chu showed how invisibility can be achieved with special technologies and materials. He asked workers to hold a panel in front of him. 2. (initial), the lower part of his body was visible through the panel. After rotating(旋转) the panel 90 degrees, his lower half disappeared, but the stage behind him could still be clearly seen. The magic 3. (realize) by a lenticular grating composed of rows of tiny cylindrical convex lense, and each vertical cylindrical convex lens can shrink and thin objects parallel to it, so that light can be refracted, according to Chu. When a row of cylindrical convex lenses 4. (form) a grating, several images 5. are too small to be noticed by the eyes are produced, achieving an invisibility effect. He then showed several other ways 6. (be) invisible, such as using two substances with similar refractive indices and a plane mirror to create reflection imaging. "Invisibility in science fiction will become reality as invisibility technology and material develop," he said. "More invisibility equipment will change our life, such as invisible rooms that can provide better privacy and invisible hearing-aids." 中国科学院院士褚君浩周六在上海表示，未来每个人的衣柜里都会有一件哈利-波特的隐形衣。 在中国主要视频共享平台 Bilibili 举办的 "超级科学之夜 "上，褚院士展示了如何利用特殊技术和材料实现隐形。他让工人在他面前拿着一块面板。起初，他的下半身可以透过面板看到。将面板旋转 90 度后，他的下半身消失了，但他身后的舞台依然清晰可见。据朱棣文介绍，这种神奇的效果是通过一个由一排排微小的圆柱凸透镜组成的光栅实现的，每个垂直的圆柱凸透镜可以将平行于它的物体缩小变薄，从而使光线发生折射。当一排圆柱凸透镜形成光栅时，就会产生几个小到眼睛无法察觉的图像，从而达到隐形的效果。然后，他展示了其他几种隐形方法，例如使用两种折射率相似的物质和平面镜来产生反射成像。 "他说："随着隐形技术和材料的发展，科幻小说中的隐形将成为现实。"更多的隐形设备将改变我们的生活，比如可以提供更好隐私的隐形房间和隐形助听器"。 2023高考链接：Ancient ruins discovered in central China's Henan 中国河南中部发现古代遗迹（曹操墓守卫） Chinese archaeolog
