2015考研英语阅读现代炼金术

　　合成一种新元素非常复杂。GSI的粒子加速器中的钛原子必须有足够快的移动速度来克服自身质子间的斥力与锫质子间的斥力，却又必须足够慢，以防将还没时间稳定下来的新合成元素119号撞裂。尽管需要良好的混合，Dullmann博士相信，在接下来的几个月中，会合成一两个119号元素的原子，并能稳定足够长的时间以被检测到。

　　That will be a feather in GSI s cap in its friendly competition with the Lawrence BerkeleyNational Laboratory, in California and the Joint Institute forNuclear Research in Dubna, Russia . Number110 is named darmstadtium, and these three laboratories are, between them, responsible forthe creation of all the transuranics found so far-most notably plutonium, which was used toblow up Nagasaki in 1945 and thus end the second world war.

　　在与加利福尼亚州的劳伦斯伯克利国家实验室和俄罗斯杜布纳的联合核研究所竞争的过程中，合成119号元素将会是GSI值得自豪的卓越成就。GSI实验室合成了110号元素，它也因此被命名为鐽;不止如此，这三所实验室合成了迄今为止所有的超铀元素。尤其引人注目的是钚，正是1945年在长崎爆炸的原子弹所使用的元素，也因此结束了第二次世界大战。

　　The islands of the blessed.

　　有福之岛。

　　Modern transuranic research is more peaceful than it was in the 1940s. Indeed, scepticsmight wonder at the value of creating new elements a mere atom or two at a time for littlereason other than to show that it can be done. There is, however, method in the madness.Just as technetium and promethium are islands of instability in parts of the periodic tablewhich are not normally radioactive, so many physicists believe that in the unstable part atthe bottom there lies an island of stability. Their prediction is that nuclei containing 184neutrons will hang around for sensibleamounts of time-possibly as long as several million years. That would at least give them achance to be useful.
