The corrosion fatigue crack growth and near-threshold characteristcsof high tensile steel HT60 were investigated by using the compact specimens underexposure to synthetic sea water. The da/dN vs △K_ relation in air may be conser-vetivel estimated for that in sea water. In the high △K region with high stressratio, owing to the acceleration of crack growth promoted by stress-induced dissol-ution, the crack opening stress intensity factor K_ represents only the result ofcrack surface in contact with corrosion products, so as to give an overestimation ofK_ at crack tip.

对高拉力钢HT60的腐蚀疲劳裂纹扩展特性和门槛值区域特性，采用紧凑拉伸试件在人工海水中进行了实验和研究，结果表明：在空气中的da/dN与ΔK_关系可以作为在海水中的da/dN与ΔK关系的一个偏保守的预测；在高应力比的高ΔK区域，由于应力诱起溶解促进了裂纹扩展的加速；该裂纹开口应力强度因子K_仅反映了裂纹表面同腐蚀生成物接触的结果，从而导致了K_在裂纹尖端的偏大的估计结果。

The main factor affecting the frequency characteristic were given as the following:the coefficient of corrosion of the Al foil surfaces the figure of the hole of scorrosion,and the character of the oxide film on the surface of the anode and cathode;the fabric of the unimpregnated liner in the capacitor,as well as the resistance and steeping of the working electrolyte and the construction of the capacitor.

影响频率特性的主要因素有：阴极和阳极铝箔表面腐蚀系数的大小及腐蚀坑洞的形状；阴极和阳极铝箔表面氧化膜的性质；电容器中衬垫纸的构造；工作电解液的电阻和浸渍情况以及电容器的内外结构尺寸等。
