  1. The author suggests that the three lithosphere - scale faults, lancangjiang fault, jinshanjiang - ailaoshan fault and axis fault in the middle of the basin, are the main geological structures that control the formation of basin, magmatism and metallogenic congregate district. the anticline structure with an axis of triassic strata and the related fault system within the basin, and gonglang arch - shaped folding structure in the south of the basin are the geological structure controlling the formation of ore fields. junctions of two or more faults with different orientation, interlayer cataclastic structural zone and oxidation - reduction ( redox ) boundary were the favorable position for the formation of ore bodies

  5. While putting rough set theory into practice, this thesis pays attention to setting - up the proper data structure. in order to improve the data utilization ratio and promote rule quality, this thesis puts forward the method of " divide equally and examine each other this thesis bring forward the method of dynamic reduce to overcome data noise and confirm the best reduction finally with the help of rosetta tool software we apply the above concept and method to reality, and succeeded in obtaining the optimum rule for the expert system of production scheduling in daye iron ore mine, wuhan iron and steel company

    由於標準粗糙集模型對數據噪音高度敏感以及工程應用中數據噪音引入的不可避免性，標準粗糙集模型在實際應用中存在一系列問題，為克服數據噪音以及規則泛化的需要，本文採用變精度模型，由此模型引入近似約簡方法。本文在將粗糙集理論及變精度粗糙集模型應用於實際的同時，注重研究了適當數據結構的建立。為提高數據利用率，提升規則生成的質量，提出了平分互測規則集泛化能力考核方法。
