然后，在猫眼石结构表面用电沉积法镀上一层镍膜，之后把猫眼石蚀刻掉，再经过电解抛光，增加这些镍膜空隙度。

After that, a layer of nickel was electrodeposited on the opal, which was then etched away. The porosity of the nickel layer was then increased using electropolishing.

电镀：利用电解原理，使金属或合金沉积在制件表面，形成均匀、致密、结合力良好的金属层的过程。

Electroplating: use the principle of electrolysis, the metal and alloy parts deposition in the surface, form even, density, good adhesion of the metal layer process.

而所谓电镀锌就是利用电解，在制件表面形成均匀、致密、结合良好的金属或合金沉积层的过程。

And the so-called electro galvanizing is the use of electrolysis, the formation of uniform, dense, combined with the process of metal or alloy deposit on the surface of workpiece is good.
