查询词典 Zn

Due to the high concentration of Zni, as-grown ZnO is n-type semiconductor. Zni have strong compensation to the p-dopant, so the dopant should be screened in order to obtain effective p-doped ZnO.

The performance and mechanism of corrosion inhibitions of POCA were studied bymethods such as weight-loss, electrochemistry, EDS, XPS and quantum chemistry. It isfound that POCA is cathodic corrosion inhibitor, having synergistic effect with HEDP andZn~(2+). The P and O atoms of phosphono have important electron density contribution toHOMO orbital and the electron gross orbital population is bigger than 1, so it is easy toform absorbing location between phosphono and metal resulting in good corrosioninhibition on mild steel.

通过利用失重法、电化学方法、扫描电镜、X光电子能谱、X-射线能谱和量子化学方法研究膦酰基羧酸的缓蚀性能及其机理，发现POCA是一种阴极型缓蚀剂，与HEDP、Zn~(2+)具有优良的协同增效作用；POCA分子中的膦酰基基团的P原子和O原子对HOMO轨道电荷密度贡献较大，且其轨道电子布居数均大于1，因此比较容易通过膦基与金属形成吸附位而对碳钢具有良好的缓蚀作用；对铜合金具有一定的腐蚀作用，但腐蚀作用比HEDP等有机膦药剂要小得多，同时与BTA具有优良的相容性，添加1mg／L的BTA则可以有效地防止铜合金的腐蚀。

A study of regional geological setting and ore-control factors for the Xiasai Ag-Pb-Zn deposit indicates that NW-trending structures act as conduits for ore fluids and orebodies are controlled by a NNw-trending fault system, while ore shoot s are confined equidistantly to secondary structures associated with the NNW-trending fault system.
