乙酸铜

On the condition of the existence of the buffer solution of ammonium acetate (PH5-6) and ammonium thiocyanate, quantitatively reduce Cu2+ into Cu+ by using sodium thiosulphate .

本文在PH5-6的乙酸铵缓冲溶液及硫氰酸铵存在下，用硫代硫酸钠定量还原Cu~(2+)为Cu~+，Cu~+与SCN~-结合，形成稳定的硫氰酸亚铜白色沉淀，反应终点可由全自动电位滴定仪确定。

CH3OH has been designed, synthesized and characterized by X-ray diffraction analysis. In this dinuclear complex, it is worthy of notice that the source of tridentate chelate atoms (1N2O) of IDA is different from that of the reported complex.

合成过程中，我们还首次得到了与1，10-邻菲咯啉及亚氨基二乙酸络合的铜的不对称双核配合物晶体。

Copper acetate meta - arsenite.

乙酸亚砷酸铜。

Copper ion was assembled onto DL-cysteine membrane that was directly assembled on the gold surface via Au-S bond, and then NAA was assembled onto the Cu/Cys/Au via coordinate function between NAA and Cu~(2+).

2利用过渡金属铜离子的桥联作用将萘胺乙酸作为桥联配体间接组装于单层膜Cys/Au上，构建另一类自组装多层膜体系NAA/Cu/Cys/Au。

Only the molar ratio 0.3 mol% of copper o-toluenesulfonate to alcohol or phenol was efficient to complete the reaction in a short time.

在乙酸存在条件下，体系的催化性能有显著提高，邻甲基苯磺酸铜用量仅需0.3 mol%就能使反应在较短时间内完成。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
