Orebodies occur in a fault near the axial region in the southern limb of the Jinjinghe-Hujiamiao inverted secondary anticline in the southern limb of the Hongyansi-Heishan composite syncline. Host rocks are dolomitic rocks in the middle and upper parts of the Devonian Qingshiya Formation. Their spatial distribution is obviously controlled by an interlayer fracture-fissure zone near the axial region in the steeply dipping southern limb of an anticline. Ores are dominantly of nodular and stockwork types and the feature of epigenetic mineralization is very pronounced.

我们首次探索了一些前人未研究过的新显色体系，使用氨基G酸偶氮氯膦，磺胺偶氮氯膦，对马尿酸偶氮氯膦建立了测定矿石中Pd的流动注射分光光度法。

Bioleaching, by means of natural populations of Thiobacillus ferrooxidans and related Thiobacilli, for example, allows recovery of up to 70% of the copper in low-grade ores.

生物萃取，例如应用天然的氧化亚铁硫杆菌菌群和相关的硫杆菌，使低品级的矿石中铜的收率达到70％。

High titanium pattern vanadic titanomagnetite is smelted in normal blast furnaces at Pan Steel. BF operation is naturally distinct from those smelted with ordinary ores.

攀钢高炉是以普通高炉冶炼钒钛磁铁矿的高炉，有其特殊性，攀钢的焦炭冷态强度较好，热性能较差。

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。
