In borate or phosphate buffered NaCl solutions with a constant total concentration of borate or phosphate, E_ increases with an increase in pH. With the increase of the concentration of chloride ions, E_ decreases markedly in the test solutions. Moreover, the buffer capacity and concentration of nonaggressive anions in the test solutions also exerts some effects on the crevice corrosion of Type 304 stainless steel. Furthermore, the cooperative inhibition effect of the environmental factors on crevice corrosion was investigated. The potential of crevice corrosion E_(cc shows a strong dependence on a parameter J, which was called as general environmental factor and defined as the product of concentration of nonaggressive anions, pH, buffer capacity and concentration of chloride ions.

在含NaCl 的硼酸或磷酸盐缓冲溶液中，在相同的缓冲溶液总浓度下，E_c随pH 值增加而增加；但随着氯离子浓度的增加，E_c显著降低；另外缓冲容量及其阴离子对304 不锈钢缝隙腐蚀也有影响；最后实验研究了这些环境影响因素的协同影响规律，得出环境综合影响因素参数J，J 由pH 值、缓冲容量、氯离子浓度及其缓冲溶液中其它阴离子浓度定义，缝隙腐蚀电位与参数J 有好的线性关系。
