氢是最简单的原子,又是宇宙中丰度最大的元素。分子氢是氢的常见形式。超高压下分子氢的相变是80年代理论和实验极感兴趣的课题。然而,地球深部是否存在分子氢?这是一个重大的疑问。 继在金刚石中发现含钾、钠和铜的氯化物包体之后,我们在对辽宁和湖南金刚石的
Hydrogen is the simplest atom and the most abundant element in the universe. Molecular hydrogen is the common form of hydrogen. The phase transition of molecular hydrogen under ultrahigh pressure is a subject of great interest in theory and experiment in the 1980s. However, is there any molecular hydrogen in the deep part of the earth? This is a major question. Following the discovery of diamond inclusions containing potassium, sodium and copper in diamonds, we found that diamonds in Liaoning and Hunan
