任何电镀都必须有一个能产生正常镀层的电流密度范围。
Any plating must have a can produce normal coating the current density range.
经分析认为:适宜的缝合线紧密度范围是130~370N。
而且该工艺具有成本较低、可操作电流密度范围和温度范围宽等优点。
Fuethermore, the technology has the advantage of lower plating cost and broader width of the current density and temperature.
And one common way to think about it, is to think about the value of r, or the radius, below which 90% of that electron density is going to be contained.
而通常的想法,是想象,r,的值,也就是半径的值,即有百分之九十的电子密度,都落在这个范围之内。
