据英国《新科学家》周刊1991年3月16日报道,两年前,美国一个科家小组宣布,在极大的压力下压缩氢气,使氢气转变成了金属(本刊1989年第5期科动态中对这一消息作过报道)。现在看来,他们的结论是不可靠的。据其他一些科学家的意见,有可能是在试验的容器内因化学反应产生的铝沾污了氢气样品。科内尔大学的阿瑟·劳夫(Arthur Ruoff)和克雷格·范德博格(Craig Vanderborg)怀疑已制取金属氢的结论。因为1989年戴维毛(David Mao)及其同事在华盛顿卡内基研究所用金刚石钻座对氢气施加约149万个大气压时发现,有5％的入射光被反射出来,他们就认为这是氢气已变成为金属。
According to a report by the British “New Scientist” magazine on March 16, 1991, two years ago, a team of scientists from the United States announced that it would compress hydrogen under a tremendous pressure to convert hydrogen to metal (5th ed., 1989 Dynamic news of this news). Now it seems that their conclusion is not reliable. According to some other scientists, it is possible that aluminum contaminated by chemical reactions in the test vessel contaminated the hydrogen sample. Arthur Ruoff of Cornell University and Craig Vanderborg suspect the conclusion that metallic hydrogen has been produced. Because in 1989 David Mao and colleagues at the Carnegie Institution in Washington used diamond burners to exert about 1.49 million atmospheres on hydrogen and found that 5% of incident light was reflected, which they considered to be hydrogen Has become a metal.
