白铜

It has been pointed out that a major contribution made by the book is the find and research of the archives of Mathew Boulton,a businessman who was closely involved in the story of Paktong during the late eighteenth century.

该书的主要学术贡献在于发现了英国 18世纪后期著名工业家马修·波尔顿的档案资料并做了深入地研究，从而找到了一批重要的新史料，使白铜史上的一些疑难问题得以澄清。

Influence factors on semiconduction properties of oxide films on a cupronickel electrode in the simulated water was studied by cyclic voltammetry and photocurrent response method.

用动电位伏安法和光电化学方法对模拟水中白铜B30耐蚀性影响因素进行了研究。

Experiment results indicated that the anodic processes of copper, cupronickel-welded joint and brass-welded joint were similar in artificial seawater. At the same electrode potential, the corrosion current of cupronickel was the lowest and the corrosion resistance was the best, which is consistent with the EIS result.

结果表明：紫铜、白铜焊缝和黄铜焊缝在人工海水中的阳极过程类似，相同电位下，白铜焊缝的电流密度最小，耐蚀性最佳，与阻抗测试结果一致。

Wang Du is a world famous Wuhan native artist, this "Mode - Artist Wang Du Art Exhibition" will for the fist time display his six cupronickel sculptures named "Mode, 2006-2007" in domestic.

王度是享有国际声誉的武汉籍艺术家，这次"模式--旅法艺术家王度特展"是其6件被命名为《模式，2006-2007》的白铜雕塑作品首次在国内的集体亮相。

Cupronickel scabbard,fragmentary hilt,double blood slots on blade,of two hanging styles.

此鞘为白铜，刀柄残缺，刀刃双血槽，有两种挂式。

The results of scientific analyses of more than one hundred artefacts of Paktong presented in the book are also significant to further study of the history and technology of paktong...

该书的另一贡献是提供了上百件白铜实物的科学分析结果，为鉴别中国白铜及其仿制品德国银提供了重要的科学依据。

In order to recover nonferrous metals in copper-nickel alloy scrap, a corresponding technology was adopted as follows crushing copper-nickel alloy scrap→leaching the sample with sulfuric acid→extracting copper ion with N902→extracting zinc ion with P204→getting nickelous sulfate solution.

摘 要：采用粉碎白铜合金废料→酸浸出→N902萃取分离出铜离子→P204萃取分离出锌离子→水相中剩余硫酸镍溶液工艺回收白铜合金废料中的有色金属。
