1·According to the condition of ore body, selected mining method and proportion of each mining method, and through calculation, the mining loss rate is 12% and the impoverishment rate is 15%.
根据矿体赋存条件和所选用的采矿方法，各种采矿方法所占的比例，计算采矿综合法损失率为12%、贫化率为15%。
2·Establishing the ore body model, the loss impoverishment dynamic model and the ore matching optimization model.
建立了矿体模型、损失贫化动态模型和配矿优化模型。
3·Generally, the elements in strata do not show a whole impoverishment, so the strata do not provide any material to form the layered ore deposits in Tongling area.
地层中元素整体贫化的现象很少，说明铜陵地区的层状矿床或层控矿床的物质来源主要不是来自地层。
4·In particle filters (PF), sequential importance sampling will result in sample impoverishment and further the loss of diversity after resampling.
粒子滤波算法(PF)中，序列重要性采样引起采样点贫化，进一步经过重采样后造成分集度损失。
5·The selective reduction impoverishment of slag from copper smelting with addition of charcoal powder and stirring of inert gas is investigated by the aid of metallurgical analysis, SEM and EDX.
借助于金相分析、SEM和EDX等方法，研究炼铜炉渣加炭粉、通惰性气体搅拌选择性还原贫化过程。
