The industrial test for Lanping lead-zinc oxidation mine was carried out in this paper.The results showed that too low recovery rate of zinc was not induced by the flotation process of oxidation zinc mine,and the key point of solving the problem lied in how to reduce the produce rate of gangues and how to increase the recovery rate of the metals in gangues.The economic benefit of this process was also evaluated,the result showed that the economic benefit was obvious when the ores of Jiaya Mountain were trea...

对兰坪铅锌矿氧化矿进行了500t/d的工业试验研究，结果表明，氧化锌回收率较低的原因并非氧化锌浮选工艺的问题，如何降低矿泥的产率和能否回收矿泥中的金属将是解决兰坪难选氧化铅锌矿的关键所在，同时也对该工艺进行了经济效益评估，采用现行工艺处理架崖山工业矿具有一定的经济效益，在进一步完善现有工艺的基础上，具有一定的应用前景。

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。
