The optimal cp potential shifted to negative direction in seamud containing active srb , - 1030 mv ( vs . saturated cu / cuso4 electrode , cse ) or lower potential was needed . accordingly , the cp current density was about 11 ma / m2 在srb存在下，最佳阴极保护电位移向更负的值， - 1030mv （相对铜/硫酸铜电极， cse ）甚至更低的电位是需要的。在- 1030mvcse保护电位下，保护电流密度约为11ma / m2 。
Nano - cuo powders were successfully prepared by pressure - hydrothermal method with cuso4 5h2o and naoh as materials . xrd , sem and tem were used to characterize the samples . the influence of raw materials " initial concentration , thermal treatment " temperature , pressure and thermal treatment " time on the morphology and size of cuo were analyzed , and the possible growth mechanism was also discussed 以硫酸铜和氢氧化钠为原料，用压力-热液法合成了纳米氧化铜粉体，用xrd 、 sem 、 tem对所制得的氧化铜进行了观察与表征，分析了原料起始浓度、热处理温度、压力、 ph值及热处理时间对氧化铜形态和大小的影响，初步探讨了不同形态氧化铜的生长机理。
The corrosion behavior of nanocrystalline ( nc ) copper bulks with various grain sizes prepared from igc ( inert gas condemsation ) and vacuum annealing in comparison with conventional microcrystalline ( mc ) copper ( as - rolled and electrolytic ) in acid copper sulphate solution and neutral solution containing chlorides under free corrosion conditions and anodic polarizations has been studied using potentiodynamic polarization , potentiometric analysis , cyclic voltammetry and electrochemical impedance spectroscopy . x - ray diffraction was used to estimate the grain size of the annealed nc copper . field emission gun scanning electron microscopy and x - ray energy - dispersive spectroscopy was used to characterize the surface morphology and analyze the surface composition after the polarization and potentiometric test of both nc and mc copper 本文研究了用igc (惰性气体蒸发凝聚原位温压法)制备并真空退火到不同晶粒尺寸的纳米晶铜和微米晶铜(冷轧紫铜、电解铜)在酸性硫酸铜溶液和中性含氯溶液中，在自腐蚀状态和阳极极化状态下的腐蚀性能。使用了动电势极化、电位测定、循环伏安法( cv )和电化学阻抗谱( eis )等方法。 x -射线衍射( xrd )的方法用来估算纳米晶铜晶粒尺寸。

So it is important to reveal the mechanism of uptake and release of copper in hepatocyte , we aimed to purify a novel copper binding protein from rat liver lysosomal fraction . researches show that copper binding proteins have conserved amino acid sequences - mxcxxc ( x is any amino acid ) , can bind with copper . for example atp7b has five mxcxxc sequence , and it was determined 1 mol atp7b can interact 5 mol of copper ions Irene等人的研究表明钢结合蛋白具有高度同源性的钢结合氨基酸序列，从酵母等低等动物到真核细胞n末端都有mxcxxcx代表任意氨基酸厂是钢结合的区域，例如ai ” ob的n末端就有5个mxc状c结构，实验也证明一摩尔的蛋白质可与5摩尔的硫酸铜结合。
It was found that before the plating , there is section time to gestating , that we call the " gestating time " and the plating was ended spontaneously after some time , named " plating time " . the analysis of the solution after plating indicated that the too much decrease of ph value results in the reaction to be stopped . the plating time was shortened when the ph and the temperature of the bath were increased 结果表明，镀液ph浙江大学硕士学位论文范启义2003年3月摘要值、施镀温度提高，由于反应的速度加快，使反应时间缩短；硫酸铜浓度提高，有助于加快反应速度，从而缩短反应时间； edta浓度提高，使镀液稳定性升高，对反应时间的影响等效于硫酸铜浓度的降低；而甲醛浓度提高，虽然反应的速度加快，但由于可用于还原的量增加，因此反应时间增加；装载量提高，因能镀覆的表面积增加，使反应时间缩短。
