This paper probes into some facters which have influence on the eelectroplating speed and the quality of the plate,using the method of single factor analysis.

本文用单因素分析法对一些影响镀速及镀层质量的因素进行了考察。

The thermodynamics and the dynamics mechanism have been studied.The results show that it is advisable for the HCHO and NaH_2PO_2 as the reduction due to the electrode potential of the reduction is more negative than that of Cu~ 2+ from the analysis of data in thermodynamics.It is advantage for the reaction of electroless copper in the alkaline solution. According to the analysis of Tafel slope of a cathodal polarization curve,...

结果表明：从热力学数据分析看，还原剂的电极电位皆比铜离子负，用甲醛、次亚磷酸钠做还原剂还原Cu2+在热力学上是可行的，在碱性溶液中对化学镀铜反应有利；从阴极极化曲线的Tafel斜率分析看，Cu2+=Cu+步骤为阴极反应的速度控制环节；从镀液的旋转圆盘电极测试结果分析看，电子跃迁步骤H2CO-ad rdsHCOOH+1/2H2+e-为镀液中阳极反应速度的控制性步骤。

The results show that using 2, 2-Bipyridyl and sodium thiosulfate can increase brightness of coating, enlarge the scope of current density.

试验结果表明：2，2-联吡啶和硫代硫酸钠联合使用可以提高镀层的光亮性，扩大镀液的电流密度范围。

Meanwhile, the relationship between several processing parameters, such as formula of silver-plating solution, its PH value and plating temperature, and silver-plating speed is to be studied.

同时研究了化学镀银液的配方组分、镀液的PH值及施镀温度等工艺参数和化学镀银速率之间的关系。

Reel-to-reel Selective Planting Design:Guide wheel,sparger,masking belt and spot wheel plating tools are erected on SS franes which are imbedded in PPmaterial and installed in PP tank.

轮式点镀单元由不锈钢机架外表面包PP安装在PP柜内，机架上安装导向轮、喷头、遮蔽带与点镀轮模具等。

At present,this apparatus is used mainly for the examination of the perfectness of convergent spherical wave surface with aperture angle≤1:3,hence it can be used for the non-contact direct test of aluminized or unaluminized concave mirrors with any ...

因此可以用来无接触的直接检验任意口径的镀铝或未镀铝的凹球面镜；加入辅助镜后可以检验平面镜、天文望远镜用的各种非球面镜、介质的均匀性、光学系统的质量、光轴校正及安装变形情况；也可给出物镜对于现用激光波长(6328)的波面差及测出某些象差。

Styles, biggest changes is in the color seeming:In front and back splash guard, fuel tank cover, car wheel , row spirit, in front and back avoid earthquake, enter spirit way etc., include originally the chrome, silver-plating part all change for pure black, assume a new aspect, felling more parties, more overbearing

96款，最大的改变就是在颜色外观上：前后挡泥板、油箱盖、车轮毂、排气、前后避震、进气道等等，包括原来镀铬、镀银的部分全部改为纯黑色，面目一新，感觉更硬派，更嚣张！

The process has features of wide range of current density, stable solution and good deposit properties.

本工艺具有施镀电流密度范围宽、液稳定可靠以及镀层性能优越等特点。

The main reason for protect invalidation of coating is the disfigurements existing in the surface and interior of coating, which can be decreased by improvement of electroless nickel plating solution and strict control over technological parameters.

导致Ni-P层防护失效的主要原因来自于试样表面及镀层内部的缺陷，通过改进化学镀镍工艺配方和严格控制工艺参数能减少镀层缺陷的产生。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
