First of all, this study will be multi-walled carbon nanotubes by chemical oxidation process purified so it can be modified to deal with than the purification of purity before the modified 5 wt%, more than 1.89 times the surface area to increase the surface potential decrease of about 10 ~ 20 mV and the surface functional base (-COOH and-OH) to increase 1.45 times, and then the control technology of electroless preparation parameters include: analysis of plating time, plating analysis of temperature, metal ions in solution than the (Fe2+/ Ni2+), bath pH and the added value of dispersion Agent and other research towards Fe-Ni particles to increase the iron content and Fe-Ni particles spread in the MWCNT upper fixed targets,the results found that when the parameters for the preparation of 50 ℃, pH10, do not add dispersant, metal ions than the solution (Fe2 +/ Ni2 +) 7, the highest iron content can be Fe = 40.55 at%(flat iron content 111.17 mg / g) of nanocomposites Fe-Ni/CNT, then for a series of the nature of its analysis, the final evaluation Fe-Ni/CNT nanocomposites were processed on the effectiveness of the application of mixed pollutants, the results showed that in 120 minutes at the same time when Adsorption of heavy metal ions lead nitrate 10 ppm, selenium heavy metal ion degradation of 1 ppm and orange azo dye AO7 50 ppm standard of effluents, and after a total Fe-Ni nano-particles to SEM / EDS analysis of more than 50% still remaining.

本研究首先将多壁奈米碳管以化学氧化法做纯化改质处理能使其纯度较纯化改质前提高5 wt％、比表面积提高1.89倍、表面电位下降约10~20 mV以及表面官能基提高1.45倍，再控制无电镀技术之制备参数包括：析镀时间、析镀温度，镀液中金属离子比(Fe2+/Ni2+)、镀液pH值及是否添加分散剂等，研究朝提高Fe-Ni粒子的含铁量与Fe-Ni粒子散布固定在MWCNT上等目标进行，研究结果发现当制备参数为50 ℃、pH10、不添加分散剂、镀液金属离子比(Fe2+/Ni2+)7时，可得到最高铁含量Fe = 40.55 at％(单位铁含量111.17 mg/g)之奈米复合材料Fe-Ni/CNT，接著对其作一系列性质分析，最后评估奈米复合材料Fe-Ni/CNT对共处理混合污染物之应用效益，结果显示其在120分钟时能够同时吸附重金属硝酸铅离子10 ppm、重金属硒酸根离子1 ppm及降解偶氮橘色染料AO7 50 ppm达放流水标准，且共处理后奈米Fe-Ni粒子以SEM/EDS分析仍剩余50 %以上。

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。
