查询词典 carbureted hydrogen

It is revealed that natural diamonds may contain as much as 59 different trace elements. The concentration of each trace element is above 1 ppm(10〓). However, the major impurities are nitrogen, hydrogen, oxygen and boron. The study of the forms of hydrogen in diamonds not only enriched the contents of mantle mineralogy, material sciences and gemology, but also provided some important informations for dealing with some problems concerning the Earth's mantle and core.
