The current density peak of brass welded line appeared at -0.012 V, and a porous corrosion film was formed. The electrode was passivated subsequently. The passivation film was made up of Cu2O, CuCl and ZnO. The passivation film dissolved with electrode potential, and displacement deposition took place between Cu and Zn. The copper redeposition on the electrode surface induced the increase of electrode activity and corrosion rate.

黄铜焊缝在电位-0.012V时出现电流峰，腐蚀产物膜多孔、疏松，随后电极进入钝化区，钝化膜由Cu2O、CuCl和ZnO组成；随电位升高，钝化膜溶解，发生铜锌置换反应，沉积的Cu导致活性电对的形成，增加了合金的腐蚀速度；当电位为+0.87V时，电极表面富集了针状锡和锡的氧化物。

Dealing with the spectrum data with the method of multivariate calibrations of chemometrics, we can simultaneously analyze the measured spectrum of mixture.

基于这三种金属离子均能和4-（2-吡啶偶氮）－间苯二酚发生显色反应，但所生成络合物的吸收光谱重叠比较严重，采用化学计量学的多元校正方法，解析了Cu(上标 2+)、Zn(上标 2+)、Mn(上标 2+)混合物的测量光谱。

In a word, according to the research of pulp wastewater treatment using pond-reed system, we discovered that the complex system can removal wastewater pollutants effectively, at the same time, the salinity of soil is dramatic decreased through wastewater washing, which bring many active results: increasing of N, P, and organic matter; enhancing of soil microbes, enzymes, MBC/TOC, and soil respire rate; increasing of reed height and yield, decreasing of weed diversity; affecting of transporting ability of Ca, Mg, K, Zn, and Mn , and improving of water shortage, salinity resistance and rhizosphere metabolized secretion conditions, all those improved the weak ecosystem.

总之，经过对生物塘-芦苇湿地系统处理造纸废水的研究，发现系统能有效去除废水中有机物，同时废水灌溉还极大的降低了土壤盐分，产生了一系列积极效应：系统内氮、磷、有机质增加；土壤微生物和酶活性增强；MBC/TOC及土壤呼吸强度提高；芦苇株高和产量增加，而杂草的多样性减少；同时也会影响系统内钙、镁、钾、锌、锰等离子迁移，改变系统受盐碱和缺水胁迫的现状和根际代谢状况，极大地改善了滨海盐碱生态系统现状。
