crustal abundance
Examples
- With the new analytical techniques of platinum - group elements ( pge ) published after 1990 ' s and a huge amount of reliable analytical data of pge accumulated at present , it is found that the data of pge abundances in crust , crustal rocks and sediments published before l980 ' s are not suitable as an evaluating criterion
摘要随着20世纪90年代铂族元素分析测试技术的突破性进展以及大量可靠的岩石和沉积物铂族元素含量分析数据的积累，引用20世纪80年代前发表的有关铂族元素的地壳丰度和岩石、沉积物中的平均含量作为衡量标准已不适宜。
