Through the study of characteristic of macroelement, microelement, rare - earth element, oxyhydrogen isotope, sulfur isotope, lead isotope, fluid inclusion etc, a conclusion can be drawn that metallogenic substance comes from the upper mantle with mixing of some substance from the upper crust latter. it is likely to have the same source with the surrounding rock
通過對礦床的常量元素、微量元素、稀土元素、流體包裹體特徵、氫氧同位素、硫同位素、鉛同位素等特徵的研究，認為成礦物質主要來源於上地幔，與周圍巖石存在著同源的可能性，後期有一定的上地殼物質混入，成礦作用有三期，分別與區內的花崗巖、二長花崗巖脈、雲煌巖脈有關。From the study of lanthanon, we know that quart - vein is the single production of hydro mineralization. etch rock and mineralized rock are the mix outcome of hydro mineralization and wall rock materials
稀土元素研究結果反映石英脈是成礦流體的單純產物，而蝕變巖和礦化巖石則是成礦流體與圍巖物質的混合產物。In chapter 3, the subgrid eddy - viscosity model for large eddy simulation is applied to calculate the three dimensions unsteady periodic turbulent flow in yantan francis turbine. the pulsating characteristics of some main physical parameters in flow field are found. the calculated axial water thrust of hydraulic turbine agrees with the model - test value
第三章採用大渦模擬亞格子渦粘模型，對巖灘混流式水輪機的流場進行三維非定常湍流分析，得到了流場中各物理量的脈動特性，計算出ms的軸向水推力與模型試驗值大小相當；同時論證了對于下機架承重的混流式水輪發電機組可採用其推力軸承負荷作為水電站廠房振動的最大垂直激振荷載。According to the geological conditions and the corrosive medium composition of the shaft well ， the damaging reason and the mechanism of the concrete attack in the intake shaft well of “ 635 ” project are analyzed ， and the corrosion - prevention treating method for the shaft well concrete is presented
水利樞紐發電引水洞豎井段圍巖中，有黃鐵礦脈風化形成的黃鉀鐵礬化蝕變帶通過.經對豎井襯砌混凝土腐蝕破壞機理的分析后認為，必須採用有效的防腐材料，將混凝土與侵蝕介質隔離開來，對豎井混凝土進行防腐蝕處理分享友人
