As one of the important indexes for the quality rating of plating, porosity can be used to evaluate the protection effectiveness of the substrate by the plating.
孔隙率是检验镀层质量的一个重要指标，它标明了镀层对基体防护作用的优劣程度。
Experimental results indicate that compare to single stabilizing agent, compound stabilizing agent has higher plating rate, better stability and lower porosity.
结果表明：复合稳定剂比单一稳定剂镀速高、稳定性好、孔隙率低。
Pulse electroplating coating have more powerful hardness and bonding strength than direct current plating, the amounts of crack and porosity are lower than direct current plating.
脉冲镀层硬度和结合力均高于直流镀层，镀层孔隙率、表面裂纹数量和裂纹程度都小于直流镀层。
Porosity is one of the important factors to evaluate the quality of gold plating on connectors.
