同时表明，采用高温锌阳极比采用铝阳极好，高温锌阳极效率高，而且不存在晶间腐蚀问题。
It also showed that high-temperature zinc anode performed better than aluminum anode and high-temperature zinc anode offered high efficiency and was not subject to intergranular corrosion.
高温下，铝阳极晶粒脱落和析氢自腐蚀更剧烈导致阳极电流效率下降。
At higher temperature, grains are falling and hydrogen evolution is aggravated so that the performance of aluminum anodes become less satisfactory.
