摘要: 在腐蚀发生率低,试样数量又不足够多时,用传统的计算方法不能得出合理的腐蚀发生率。根据一些逻辑推理,如在较短时间内发生了腐蚀的试样,或在较长时间内没发生腐蚀的试样,若将该试验时间延长或缩短,则仍应发生腐蚀或没发生腐蚀,推导出一种计算腐蚀发生率的近似方法。它不仅在腐蚀次发生率高,试样数量多时得到与传统方法完全一致的结果,而且在腐蚀发生率低,试样数量不够多时也能得到合理的结果。

Abstract：When the corrosion initiation rate is low and the number of samples is not great enough, the reasonable corrosion initiation rate cannot be obtained by traditional calculation. According to some logic inferences, if the samples had been corroded in a shorter test time, they should also oorroded when tested for a longer period. On the other hand, if the sampies had not been corroded in a longer test time, they should also survive when tested for a shorter period. Then a method for calculating the corrosion initiation rate approximatelly can be developed. It not only gives the result which agrees better with that obtained by traditional calculation when the corrosion initiation rate is high and the number of samples is great, but also gives a raasonable result in case where the corrosion initiation rate is low and the number of samples is not great enough.
