在低氰镀液中含量太高则电流效率下降，甚至其成海绵状镀层。
In the low cyanide solution content is too high, the current efficiency drops, and even has cavernous coating.
锌含量偏低，分散能力好，但电流效率下降。
Low zinc content, scattered capacity is good, but the current efficiency decline.
请注意，由于采用了约定的电流方向，因此每个元件中的电流是沿着电压下降的方向流动。
Note that conventional current flow is used, hence the current in each element is shown in the direction of decreasing voltage.
