周正仁同志在本刊中讨论了对称氧化还原滴定中等当点(eq)与突跃点(tp)的一致性问题。这是一个具有普遍意义的问题。这个问题在文献中已有若干论述。但由于缺乏严格的理论分析,故结论往往不一致。我们曾讨论过酸碱滴定中等当点与突跃点的一致性问题。本文利用类似的原理,拟对这一问题再次进行探讨,并求得该问题的一般性判据。

Comrade Zhou Zhengren discussed the consistency of the equivalence point (eq) with the sudden jump point (tp) in symmetric redox titration in this paper. This is a matter of universal significance. This issue has been discussed in the literature. However, due to the lack of rigorous theoretical analysis, the conclusions are often inconsistent. We have discussed the consistency of the equivalence point and the sudden jump point in acid-base titration. In this paper, using a similar principle, this issue is to be explored again and the general criteria of the problem are obtained.
