摘　　要：借助扫描电镜 (SEM)对不同实验条件下的三维电极主电极表面腐蚀状况进行研究。结果表明 ,三维电极主电极阳极的内侧腐蚀程度远大于其外侧 ,水样性质、电极材料性质对电极的腐蚀程度有很大的影响 ,不锈钢做三维电极主电极优于铝、铁电极。The state of beam electrode surface corrosion in 3D electrode is studied under different experimental conditions by using scanning electron microscopy(SEM). The result shows that the corrosion degree of internal surface is higher than that of external surface at the anode of the beam electrode, the corrosion degree of electrode depends greatly upon the properties of water sample and material of the electrode, the beam electrode made up of stainless steel is better than that of aluminum and iron , by which theoretical basis is provided for selecting materials for the beam electrode.
