The characteristics of pitting corrosion above breakdown potential E_b are studied for AISI 304 stainless steel in the solution of 1NH_2SO_4+0.5NNaCl at 25℃.

本文研究了AISI304不锈钢在25℃的1NH_2SO_4+0.5NNaCl溶液中，当电位正于击穿电位时发生小孔腐蚀的特征。

AS compared with the alloy of higher Cr content, the nucleation and growth of methetable pits for the low Cr alloy were faster,and its pitting breakdown potential Eb was more cathodic and scattered in a wider potential range.

含Cr量较低（7wt％）的合金与含Cr量较高（13wt％）的合金相比，亚稳孔的形核速度和生长速度均较快，孔蚀破坏电位Eb较负，且随机性更大。

The results showed that plastic deformation at both -70℃ and 180℃ made the dislocation density of AISI304 stainless steel increase with the increase of deformation. Martensite phase transformation was induced for deformation at -70℃, whereas it was not at 180℃. As the dislocation density increased, the breakdown potential of AISI304 stainless steel's passive film became a little more positive. As martensite phase content increased, it became more negative and pitting corrosion resistance decreased.

结果表明：加热180℃和低温-70℃条件下塑性变形均使AISI304不锈钢中位错密度随变形量增大而增加，AISI304不锈钢在-70℃条件下塑性变形时部分奥氏体相转变为马氏体相，而在180℃条件下塑性变形时不发生马氏体相变；位错密度的增加使AISI304不锈钢钝化膜的击穿电位略微正移，而马氏体相的增加使击穿电位呈负移趋势，材料耐孔蚀性能降低。

Gibreel, the tuneless soloist, had been cavorting in moonlight as he sang his impromptu gazal, swimming in air, butterfly-stroke, breast-stroke, bunching himself into a ball, spreadeagling himself against the almost-infinity of the almost-dawn, adopting heraldic postures, rampant, couchant, pitting levity against gravity.

加百列，这个不和谐的独唱演员，兀自在月光下的天空跳跃翻滚，一边咏唱着他的即兴gazal，一边在空气中划游，时而蝶泳，时而蛙泳，一会儿蜷缩成一个球，一会儿又尽情舒展开，向无限的黎明，用一种庄严的姿态，时而高昂，时而俯伏，轻率地和万有引力较着劲。
