reduction in thickness 中文意思是什麼
reduction in thickness
解釋
厚度壓下量-
Since the dry plating does not require the reduction using electricity, the dry plating has many advantages in that it permits to plate the surface of non - conductive polymer materials, and further does not use the electrolyte solution so that wastewater is not produced and the plating thickness can be readily controlled
由於不要求用電還原，干鍍有許多優點，因為它允許對非導電性聚合物進行上鍍，其次不使用電鍍液，結果不產生廢水，而且鍍層厚度易於控制。 -
