摘要
地学书刊中广泛使用的“含量”这一类量的含义比较模糊 ,会影响文献的价值。对照《量与单位》国家标准及“含量”的真实含义 ,认为最好使用确切的标准量名称及符号代替“含量”。具体表现为 :1)岩石或矿物的氧化物、微量元素或稀土元素的“含量”应为质量分数 (wB) ;2 )岩石中的矿物“含量”应为体积分数 (φB) ;3 )类质同像矿物中的端员矿物“含量”及斜长石牌号An应为摩尔分数 (xB) ;4)由岩石或矿物的氧化物的质量分数计算得到的原子“含量”应为原子数 (NB)。
The term of content has been widespreadly used as a category quantity in journals and books in earth sciences. According to the national standards, it is better for the category quantity, content , to be replaced by the following measures: the mass fraction of B ( w B) is used for the content of minor/rare earth elements or oxides of rocks and minerals; the volume fraction of B ( φ B) for the content of minerals in rocks; the mole fraction of B ( x B) for the content of the end minerals in isomorphous minerals , and the number of particle B ( N B) for the content of the main elements calculated by the mass fraction of oxides.
