Geochemical characteristics of mineral deposits in xicheng metallogenic province , gansu 熱液成礦分帶的自孤子特征
Discovery and features of vertical zonations of tidal salt - marsh foraminifera in jianchuan , north jiangsu province , china 我國蘇北建川潮汐鹽沼有孔蟲垂直分帶的發現和特征
The movement of the water in aeration zone is different at different depth , if the zero flux potentials exist in the aeration zone 當包氣帶中存在零通量面時,包氣帶中水分的運移是分帶的。
To analyse the complexity of geochemical zoning , the concepts of superposed zoning sequence and mineralization stage zoning sequence are defined , and a new method to decompose the superposed zoning sequence and recognize the superposed mineralization natures is suggested 為適應地球化學分帶的復雜性,定義了疊加分帶序列和礦化階段分帶序列的概念,提出了疊加分帶序列分解及疊加礦化性質識別方法。
The quantification indexes that token weathered degree are primary velocity , borehole rqd ( rock quality designation ) , joint space , joint number and so on , and the unloading ones are primary velocity , joint opening , borehole penetrability and so on . the compartmentalization of different weathered and load - off zones according to quantification indexes tallies with the slope geo - stress computed by finite element method 其中研究風化分帶的定量指標有縱波速vp 、鉆孔rqd 、結構面間距與條數等,研究卸荷分帶的定量指標有縱波速度、節理開度與鉆孔巖體透水性,據此劃分的不同程度風化、卸荷巖體與有限元計算的壩區河谷應力場具有良好對應性。
