Effects of the Hydrogenating treatment on microstructure and tensile strength of Mg-Li- Zn-Y-Zr-LPC alloy were studied.

研究了氢化处理对Mg-Li-Zn-Y-Zr-LPC合金显微组织和力学性能的影响规律，结果表明：铸态Mg-8.16%Li4.10%Zn-2.86%Y-0.59%Zr-2.14%LPC合金主要由Li、Zn和RE在Mg中的固溶体和Mg-Li-Zn-RE块状化合物共同组成。

The results show that dynamic leaching of heavy metals increases with decreasing pH values on the whole, but the relativity is not significant. The leaching concentration is negatively correlated with time. The calculation results show that the elements with the largest cumulative leaching amount are Fe, Mn, Zn and As, and those with the smallest amount are Pb, Sn, Hg and Cd. The elements with the highest stage lixiviating rate are Ni, Co, Cr, Mn, Cd and Cu, and that with the lowest rate is Fe. The elements with the highest values of cumulative lixiviating rate and cumulative lixiviating intensity are Cr, Mn, Co, Ni and Zn, and that with the lowest ones is Fe.

结果表明，重金属元素的动态浸出整体随pH值下降而升高，但相关性不明显，浸出浓度与时间整体上呈负相关关系；浸出总量效果较好的元素为Fe、Mn、Zn、As，较差的为Pb、Sn、Hg、Cd，其他元素中等；阶段浸出率较高的元素有Ni、Co、Cr、Mn、Cd、Cu，较低的元素有Fe，Sn、Zn介于中间水平；累积浸出率和累积浸出强度较高的元素有Cr、Mn、Co、Ni、Zn，较低的元素为Fe，Cu、Cd、Sn居于中间水平。

The results show that the damping capacity of Zn-22%Al remains constant for ageing temperature below 80℃, the warm rolling temperature. Traces of Ce and La can improve the damping capacity of water quenched and warm rolled Zn-22%Al, and decrease the reduction of the damping capacity of Zn-22%Al during ageing at 150℃.

结果表明，经水淬后80℃温轧的Zn-22%Al合金在低于温轧温度下时效时，其阻尼性能保持稳定；微量Ce，La的加入，提高了经水淬后80℃温轧的Zn-22%Al合金的阻尼性能，减缓了经150℃时效后阻尼性能的降低。

The results indicate that growth of TiN grains is blocked by doped Cu and Zn and TiN grain size decreases with increasing Cu and Zn concentration. In contrast, high Cu and Zn content induces coarse structure due to the growth of copper grains.

结果表明，掺杂的Cu、Zn可以阻止TiN晶粒生长，随掺杂量增加TiN晶粒细化， Cu、Zn含量比较高时由于金属相长大而使膜层组织粗化。

These phenomena suggest that the binding site of Zn~(2+) in the purine base of ATP is Nl at low pH and N7 at high pH and contrast to the adenosine-Zn~(2+) system where the purine base binds Zn~(2+) with N7 at low pH while with Nl at high pH.

为进一步证明上述观点，我们研究了Zn~(2+)与ATP的作用。发现加入Zn~(2+)时ATP溶液与纯ATP溶液在同一酸度下~(15)N化学位移的变化为：在高酸度(2＜pH＜5)，N-1化学位移差大于10ppm，在pH=3.73时，相差高达25ppm。

Quantitative analysis of the EXAFS spectra showed that the microscopic structure of Znon anatase TiO2 is four coordinate complex, and there are at least two types of bonding based on the average Ti-Zn distances in the second sphere.
