In the popular Harry Potter series, the most advanced dark magic, "petrification," is the process of turning people into stone.
大受欢迎的《哈利波特 》 系列中，“石化” 是一种最高级的黑魔法，见证了将人变成石头的过程。
In China, turning hydrogen, a gas, into a superconducting metal is a new kind magical pursuit with tantalizing possibilities, and a recent breakthrough in physics at the University of Edinburgh's School of Physics and Astronomy in the United Kingdom is pointing the way. Scientists there confirmed for the first time that hydrogen under extreme pressure takes on early characteristics of a metal a state they call Phase V.
中国正致力于将氢转变成超导金属，这项充满魔力的新科技将带来无限可能，而最近发生在英国爱丁堡大学物理和天文学院的物理实验的一项突破为此指明了方向。科学家在那里第一次证实了在极端高压下，氢会呈现金属的初始状态，被他们称之为第五阶段。
The discovery, which was featured on the cover of the prestigious scientific journal Nature, could lead to superconductivity at normal temperatures and revolutionize the world's energy picture.
这项研究被刊载在著名科学杂志《自然》的封面。该发现可能会引发常温状态下的超导电性，并彻底改变世界能源的格局。
And now the technology is coming to China, along with one of the world's leading hydrogen researchers, , a Canadian who co-authored the Nature article.
现在，该项技术来到了中国，与它一同前来的还有加拿大人尤金.格列戈良茨，世界领先的氢研究者，《自然》杂志的合著者之一。
Metallic hydrogen was predicted 80 years ago, but had never been observed. Because of its implications for superconductivity and hydrogen's importance in fundamental science the metallic phase has become the "Holy Grail" of high-pressure physics, Gregoryanz said.
80年前，就有了金属氢的预测，然而从未被发现。在基础科学领域，它的发现对于超导和氢气有着重要意义，因此金属相已成为高压物理学的“圣杯”，格列戈良茨说。
Previously, only five or six groups in the world, including Gregoryanz's at Edinburgh, have been able to make a high-pressure hydrogen sandwich consisting of two opposing diamonds that are pushed together as layers by a special mechanism. Such equipment was used in the recent experimental success reported by Nature.
先前，全球只有五六个小组，包括爱丁堡的格列戈良茨团队，能够用特殊仪器制作由两个正反面金刚石组成的高压氢气“三明治”层，而该设备也被用于最近的实验中并取得成功，《自然》杂志报道。
"Even though metallization of elements and compounds under pressure is not new, metallization of hydrogen, specifically, has been the Holy Grail of high-pressure physics for the past 40 years, mostly because metallic hydrogen is predicted to have very strange and fascinating properties unlike any other material," Gregoryanz said.
格列戈良茨说，即使受压，金属化元素及其化合物也并非新的，具体来说，过去40年，金属氢之所以成为高压物理学 “圣杯“，主要是因为人们对金属氢奇异特性的预测，不同于其他任何物质。
Superconducting materials transmit electricity without resistance under certain circumstances, usually at temperatures below -200℃. With just a little higher pressure, hydrogen could reach a fully metallic state, which is predicted to be superconductive at room temperature. If people can manage to make metallic hydrogen with superconductivity at te room mperature -- a temperature feasible for industrial use we can apply it to power transmission networks with zero power loss.
某些情况下，超导物质能够无阻力传输电力，通常温度低于零下200 ℃。提高一点压力的话，氢气能够达到完全金属的状态，预计能够在常温下变成超导体。如果人们能够设法使金属氢在常温下（适用于工业用途）变为超导体，我们可以将其应用于各电网，电网传输有望零损耗。
