A controlled deorbit requires the use of several core systems, including those for communications, power, and avionics. Some of the ISS machinery was not specifically certified to perform in a depressurized environment. (NASA believes that critical systems would remain operable, based on technical analyses, and emphasizes that many of these systems are already used in vacuum.) Another thing to worry about: the ISS losing control over its orientation in space. The spacecraft could start tumbling, flipping the station’s solar arrays away from the sun, taking the primary source of power with it.，详情可参考一键获取谷歌浏览器下载

ParametricGeometry 允许你用数学公式来定义形状。这里的 klein 函数生成了一个著名的数学模型——克莱因瓶。它是一个没有“内”和“外”之分的奇怪瓶子。对于初学者，你只需要知道：只要你能写出 x, y, z 的方程，Three.js 就能帮你画出模型。
也許可以理解的是，當 Instagram 上無數廣告向我承諾只要每天花不到 30 分鐘就能在 30 天內（甚至更快）教會我一門語言時，我總是反應得相當抗拒。
