The results show that in order to obtain optimal propagation results, the optimal pH is 7.0, the temperature is 28℃, the carbon source in culture medium is corn, the nitrogen source culture medium is barm.

结果表明：pH值7.0，温度28℃最适合HDF01的生长。培养基中以玉米粉为碳源，酵母粉为氮源，加入微量元素Mn及雄生素B6，HDF01的产孢量最高。

The results show that quartz cannot react with oleic irons at pH=8-10, because it is difficult to combine with metallic irons. On the contrary, clinochlore can adsorb with oleic ions because there are enough active metallic positive ions between the minerals layers which can combine with clinochlore. The clinochlore can be hydrophobic, and so the separation can be realized finally. At pH=9, the clinochlore removal rate is the maximum, the purity of SiO2 is 99.86%, and the recovery of SiO2 is 35%.

结果表明：在pH为8~10的碱性溶液中，粉石英难与金属阳离子缔合，所以，不与油酸根离子结合；而斜绿泥石解离后层间存在活性金属阳离子，可与油酸根离子发生化学吸附产生疏水作用，因而使用反浮选的方法能有效地实现二者的分离：当pH为9时，斜绿泥石的去除率最高，粉石英的纯度达99.86%，回收率为35%。

摘要嘉二2B层的粉晶云岩储层和嘉二1亚段的泥晶—泥粉晶云岩储层是川中磨溪构造嘉二段气藏的主力产层，物性较好，且平面上分布稳定，但测试成果显示，其产能相差甚远。

The high temperature metallurgical properties of several burdens for Anyang steel were investigated. The results showed that RIof high basicity sinters was better than others, but the RDI(low temperature reduction degradation index) of it was the highest; the RDI and molten dripping property of pellets and lump ores were well, so we can get rational burden structure by combining sinters for blast furnace.

系统分析了安钢炼铁生产中几种常用炉料的高温冶金性能，结果表明，安钢自产高碱度烧结矿具有较好的还原性，但其低温还原粉化率却是最高的；酸性球团矿及块矿则有着较好的低温还原粉化指数及良好的熔滴性能，能够与高碱度烧结矿搭配形成合理的综合炉料结构，满足高炉冶炼要求。
