查询词典 milling of ores

And the production had proved that in the present technological conditions before ironmaking,the sinters (70%～75%) with 1.7～1.8 basicity adding (about 25%) acid pellet and a few lump ores are the reasonable.

生产实践证明，在莱钢铁前现有工艺装备条件下，碱度为1.7～1.8的烧结矿（70%～75%）配加酸性球团矿（约25%）及少量块矿是较为合理的高炉炉料结构。

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。

Studies of Sr, Nd and Pb isotopes of various stratigraphic units, granite plutons and fluorite ores indicate that the metallogenic materials of fluorite were derived from multiple sources, and the isotopic composition of fluorite is characterized by crust_mantle mixed sources.

各地层单元、花岗岩体和萤石矿石的Sr、Nd、Pb同位素研究表明，萤石的放射性同位素组成具有壳、幔源混合的特点，成矿物质来源具有多源性。

Aiming at the currently shortage of XML streams quality detecting, this paper proposes a new forecasting method of XML streams quality by least squares support vector machines, which is used the method of XML keys' vector matrix as windows, and vector product wavelet transform to multilevel decompose and refactor the XML streams series, that can fulfill real-time checking demand of XML quality, and ensure constraint, consist- ency and integrality. For even more adapting net load, it proposes a control strategy by weight and adaptive adjustment to ensure XML streams quality.

针对当前XML数据流质量检测存在的不足，提出构建XML键的矢量矩阵作为窗口，利用矢量积小波变换多级分解与重构XML数据流，再结合最小二乘支持向量机对XML数据流质量进行预测的一种方法，满足XML数据流质量重构时实时检测的要求，保证XML数据的约束性、一致性与完整性；为了更好的适应网络负载，采取加权与自适应窗口调整等调度策略充分保证XML数据流的质量检测。
