向纯铝中加入少量金属元素，能改变铝的电化学活性，增强其抗腐蚀性能，减小负差效应。

The addition of a small amount of metallic elements in pure aluminium would change its electrochemical activity, enhance its anticorrosive performance and decrease its negative differential effect.

结果表明，经过固熔处理后，铝合金电极的电化学活性得到显著提高，但自腐蚀速率加快。

The results show that the electrochemical performance of aluminum alloy electrodes is improved markedly after solution treatment, but the self-corrupt speed of electrodes is accelerated.
