For the first time, strange alien ice has been seen forming on Earth by US researchers. This revelation was made by the researchers at Stanford University on July 8, 2017.

史上首次,美国研究人员在地球上见证奇特的「外星冰」形成。2017年7月8日,史丹福大学的研究人员实现此项创举。

The researchers dubbed the alien ice as ice seven, which forms naturally in the environment when planetary ice bodies collide.

冰冻的行星本体相撞时,被研究人员暱称为「外星冰」的「冰七」,会在太空环境中自然生成。

"These experiments with water are the first of their kind, allowing us to witness a fundamental disorder-to-order transition in one of the most abundant molecules in the universe," said study lead author Arianna Gleason, a visiting scientist in the Extreme Environments Laboratory of Stanford’s School of Earth, Energy & Environmental Sciences.

「该类型的水实验是史上首创,让我们得以目睹宇宙间其中一种最丰富的分子,从混沌到有序的一项重要转变,」研究报告主要作者、史丹福大学地球暨能源与环境科学院极端环境实验室访问学者阿瑞安纳.葛里森表示。

Most powerful X-ray lasers were used by the researchers to create ice VII with the help of Linac Coherent Light Source. Another instrument called X-ray Free Electron Laser is used to beam the compressed water.

研究员藉着「直线型加速器同调光源」的协助,使用最强的「X射线雷射」产生「冰七」。另一种称作「X射线自由电子雷射」的仪器,则被用于发送压缩的水分子。

This transformation took place in just six billionths of a second, or nanoseconds during the procedure.

水分子转变成冰七的过程仅耗时600万分之1秒,相当于6奈秒。

新闻辞典

nanosecond:名词,奈秒。例句:One nanosecond is equal to one-thousandth of one-millionth of one second.(1奈秒等于10亿分之1秒。)

transition:名词,转变、过渡。例句:The term phase transition is most commonly used to describe transitions between solid, liquid and gaseous states of matter.(「相变」一词大多用于形容物体在固态、液态、气态之间的转变。)

collide:动词,碰撞。例句:These clusters collide and merge with one another.(这些星系团彼此碰撞、合併。)
