从上图也可明显的获得，随着圆滑处理时间增加表面平均加权高度逐步下降。其

It can also be clearly obtained from the above figure that the average weighted height of the surface gradually decreases as the rounding time increases. Among them, the minimum decrease of ultrasonic treatment is 17.1%, followed by the copper-iron etching system, the total decrease is 24.6%, and the weighted average height of the KOH smoothing system is the fastest. The total decrease is 56.6%. Group data can clearly identify the best effect of KOH smoothness

从上图也可明显的获得，随着圆滑处理时间增加表面平均加权高度逐步下降。其中超声处理下降幅度最小为17.1%，其次为铜铁刻蚀体系，总的下降幅度为24.6%，KOH圆滑处理体系加权平均高度下降的最快最多，总的下降幅度为56.6%，通过这三组数据可以明确对出KOH圆滑效果最佳

It can also be seen from the above figure that the average weighted height of the surface decreases gradually with the increase of the smoothing treatment time. Among them, the minimum reduction of ultrasonic treatment is 17.1%, followed by copper iron etching system, with a total reduction of 24.6%. The most rapid reduction of the weighted average height of KOH smooth treatment system is 56.6%. Through these three sets of data, it can be clear that KOH smooth effect is the best<BR>
