primary minerals meaning in Chinese

原生矿物，未氧化的矿物。

Primary minerals are coal , copper and zinc , and agricultural products include rice , peanuts , sugar cane , fruits , vegetables and tobacco
矿产主要有煤、铜和锌，农产品包括米、花生、甘蔗、水果、蔬菜和烟草。
Abstract : this paper , by analyzing the effect of differences of mineral structure of 2 1 layer minerals , the properties of their interlayer charge and changes of some properties caused by weathering on the attractive force for interlayer cation , reached the conclusion that : the fixation capacity is determined by the ratio of the total amount of interlayer charge and that of tetrahedral charges . the relationship of interlayer cation fixation and octahedral structure of secondary minerals is probably different from that of primary minerals . the oxidation and reduction of variable valence cations can greatly influence the cation fixation capacity
文摘:分析2 1型矿物的结构差异、层间电荷性质以及在风化过程中某些性质的变化对层间阳离子吸引力的影响，对已有报道中一些矛盾的结果或不具普遍意义的结论进行了讨论.得出几个较为明确的结论：层间总电荷与四面体电荷所占比例大小共同决定矿物对层间阳离子的固定能力；原生矿物中八面体结构与层间阳离子固定间的关系对次生矿物而言，也许并不一致；八面体中可变价阳离子的氧化还原，可导致矿物固定阳离子能力发生较大变化
