镀银层

Compared with aurum, palladium and platinum as seeds, Silver is much cheaper and lower pollutional and can also activate electroless plating, although it is still rarely investigated.

我们采用激光诱导化学镀技术在聚酰亚(来源：ABC论文1313网www.abclunwen.com)胺薄膜表面上用四种方法选择性沉积金属银作为活化种，然后进行化学镀从而在聚酰亚胺表面上沉积上图形化的铜镀层。

Because it is a good plating layers of titanium and therefore will never decolorization.

因为是镀了好几层钛银的，因此永远也不会脱色。

To cover the surface of with a layer of precious metal, such as gold.

金属镀层沉淀或结合在表面上的薄的金属层，如金或银

"Early plated goods ("old Sheffield plate) are made by the process invented by Thomas Boulsover, and consist of a sandwich of copper between two layer s of silver.

早期镀覆的物品由布尔索弗发明的过程制成，透过把铜嵌入两层银中组成。

And now for the finishing touch, a spattering of silver shavings.

现在只剩最后一笔了在表面镀上一层银

In view of the weaknesses of silver deposits such as low hardness, poor wear resistance and electric contact property, nano crystal diamond particles were added into plating bath to codeposit with silver.

采用具有纳米晶织构的金刚石微粒强化银基电接触复合镀层。

The technology of the electroless silver plating on glass fiber has the advantages of simple fabrication, and uniform coating with strong adhesion, and receives more and more attention in recent years.

玻璃纤维化学镀银法具有工艺简单、所得镀层均匀且结合力强等优点，近年来引起了人们较多的关注。

Cladding silver with tiny crystal grain and bright surface can be gained in the condition of plating solution with about 25℃,PH9.0, cathode current density between 0.3 and 0.4A·dm-2 .Uniform foamed silver can be made by burning in the temperature of 600℃and reduction sinter in the temperature of between 800 and 850℃in electrodeposited polyurethane.

研究了PH值、温度、时间、阴极电流密度等对电沉积银质量的影响，结果表明：电镀液温度为25℃左右，PH值为9.0左右，阴极电流密度为0.3～0.4A·dm~(-2)，可获得晶粒细小、表面光亮的银镀层。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
