The wet plating method permits to improve the adhesion of plating layers by treating the surface of polymers with an acid to generate the concavo - convex and forming the polar functional groups ( see , metal surface compendium , plastic plating techniques , page 13 ) 湿镀方法可以改进镀层的粘附能力，其方法是用酸处理聚合物表面，以产生凸凹并形成极性基团。
Micropores have great effects on electrode especially , micropores between 2 to 5nm can increase capacity of edlc . table sugar must be activated for electrolde material as edlc some functional groups contain in material can increase capacity of edlc 这是因为活化使碳材料的比表面积和孔隙率增大，同时含氧的宫能团有利于吸附型准电容的生成，从而使材料的比容量增大。
Different functional groups were proved through fi - ir and nmr , and the key is to make different groups reasonably chained with the key group . the water - reducing ratio was 20 % at 0 . 3 % ~ 0 . 4 % dosage of the cement weight , the slump - loss in 3h was reduced greatly 合成的hp减水剂在混凝土中掺量为水泥用量的0 . 3 ? 0 . 4时，取得了减水率超过20 ，坍落度3h以上基本不损失的效果。
The magnetic composite microspheres with better size distribution and structure , possessing higher conversion rate of polymer and ideal magnetic properties were synthesized by adding an amount of dispersant , disperbyk - 106 , bearing much polar functional groups 提出了用活性游离基dpe法制备磁性复合微球的新思路，并且采用该法成功地制备了粒径小于500nln的磁性fe30尸mma一ps复合微球。
