事故率相等时的进一步评价

Further evaluation of the equal rate of the accidents

事故率相等时如何进一步的评价问题一直在实际中存在，没有解决，文[1]所给出的方法也不尽合理．本文通过有关概率的比较与解释，给出事故相等时进一步评价准则，期望对实践中解决这个问题有益。

The problem how to evalute further equal rate of the accidents is alwecys present in pratice. It hasn't been settled yet. The method in Text 1 isn't reasonable,either. The following passage woill give the criterion of further evaluation when the rate of accidents is equal by rneans of the compari sion and explanation to some probabilites. We hope it will be useful to seitle the problern in practice.
