Moreover, as one of major ore-forming elements, copper isotope composition can directly trace ore-metal source and ore-forming process. 并且，由于銅是主要成礦元素之一，所以銅同位素對于成礦物質(zhì)來源和成礦過程的示蹤更為直接。
Based on the dynamic explicit finite element scheme, the forming forces in the sheet metal multi-point forming (MPF) process were formulated. 基于動力顯式有限元格式，給出了多點成形中成形力的計算公式。
The formation of W-Au deposit (occurrences) is related with granite magma activity of Indo-Chinese epoch, and the main metal elements in ore-forming process is provided by the rock bodies. 鎢金礦床（點）的形成與印支期花崗巖活動有關(guān)，巖體為成礦提供了主要金屬元素。
