本文指出细粒煤泥浮选在选煤生产上的意义，并以一个厂的浮选工作为例对其中存在的问题加以阐述。

The negative linear correlation of TSP concentration with the magnetic parameters mass specific susceptibility , saturation isothermal remanence , susceptibility anhysteretic remanent mangetization and hard isothermal remanent magnetization discriminate the different source types from iron and steel complex, power plants, fossil fuel combustion and para-/dia-magnetic pollutants in all sampling sites.

磁学参数x〓、SIRM、x〓、HIRM显然描述了不同气溶胶的来源，这包括炼钢厂、煤的燃烧、建筑工地扬尘和风蚀土壤。而磁学参数比值的变化要低于磁学参数浓度的变化。对现代发电厂烟囱源的样品分析表明，由燃煤产生的磁性颗粒由0μm的细颗粒物占优。气溶胶中较多的磁性颗粒物可能主要来自于需经改造的陈旧技术。

Some conclusions are drawn which by analyzing the experimental data.There are seriate pores with continuous diameters in the coal, some of which are fracture-type.The pore volume of the coal is mainly...

分析表明，大同煤具有连续的完整的孔系统，且部分孔为狭缝毛细孔；孔体积主要由大孔和中孔构成，比表面积主要由小孔和中孔构成；随着颗粒粒度的减小，煤粉的孔隙结构发生变化，致使比表面积和孔容积均增大，平均孔直径减小。

It belongs to fuel processing technology field. It includes the following steps: using alumina industrial waste red mud as material; drying and grinding; adding red mud fine powder into 200-350 screen mesh coal powder by the weight of the former is 10-20% of the latter; mixing uniformly and spraying 5-10% water; forming coal ball by hydraulic press; its pressure is 10-30MPa.

本发明的氧化铝生产厂的废料赤泥为原料，烘干研磨，然后在一定量的200～350目的煤粉中添加上述赤泥细粉，加入量为煤粉重量的10～20％，经共同研磨混合均匀后，喷洒5～10％的水，再次混合均匀，随后用液压机将上述混合物压制成煤球；所用压力为10～30MPa；最终制成具有较高煤炭燃烧率的型煤。

The precision of the belt balance is bad, and closed loop control can not work well in the coal blending process.

混合煤的灰分、硫分、挥发分、水分、细度等都直接关系着焦炭的质量及能否顺利推焦。

According to successfully extracting and graphing of uranium anomalies, the self-center uranium anomalies and their close relationship with meandering stream systems have been observed. The uranium anomaly always develops in the distributary and turning place of meandering stream system, and is related with thin sand area (whose sand thickness and sand ratio are less than 30 meters and 40% respectively), thicker coal, fine lithology, but the highest value of uranium anomaly exists in middle sandstone.

通过对铀异常信息的成功提取及平面编图，发现延安组中铀异常呈一个又一个具有自我中心的单元出现，且与曲流河沉积体系的关系密切：通常发育于河道分岔或转弯处；普遍发育于薄砂带，一般砂体厚度在30m以下，含砂率小于40%；铀异常单元与厚煤层关系密切；主要赋存于粒度较细的岩性中，部分也富集于煤中，但铀异常最高值富集于中砂岩中。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.
