电子染色一次性多个载有超薄切片的铜网同时进行染色，是很难避免空气中的二氧化碳和染液中的铅反应产生碳酸铅沉淀污染切片．另外多个铜网同时进行染色，由于水和染液的吸附作用，往往产生铜网漂移，至使切片序号混乱．如果有2个以上切片的铜网同时漂移，会导致染色失败前功尽 Electron Dyeing Several copper networks containing ultra-thin sections can be dyed at the same time. It is difficult to avoid carbon dioxide in the air reacting with lead in the bath to produce contaminating sections of lead carbonate. In addition, multiple copper networks are dyed at the same time. Due to the adsorption of water and dye liquor, drift of the copper grid often occurs, so that the serial number of the chips is confused. If there are more than two slices of copper network drift at the same time, will lead to failure before done
