Based on a systematic study of a considerable number of polished ore sections as well as ICP-MS and electron microprobe analyses, the authors have found that the main sulfide minerals include galena, iron-poor sphalerite and chalcopyrite, whereas silver minerals are composed chiefly of native silver, pyrargyrite, argentite, polybasite, and argentiferous freibergite.

文章首次对其矿石矿物进行了系统的研究，通过对大量矿石光薄片观察、等离子质谱和电子探针分析，表明具有工业意义的硫化物主要有方铅矿、贫铁闪锌矿、黄铜矿，银矿物主要有自然银、深红银矿、辉银矿、硫锑铜银矿、含银黝铜矿，它们与硫化物共生，多沿方铅矿、贫铁闪锌矿等颗粒间或者裂隙产出。

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。
