二项分布是各种试验中经常遇到的一种分布类型，当前有很多参数评估方法，但是包括工程标准在内的很多方法性能并不是很优。根据二项分布离散性的特点提出了一种二项分布参数 p置信区间评估的暴力算法。算法对二项分布参数 p进行精细步长的遍历，在每一个参数值点根据置信水平对置信区间进行修正，遍历完所有的参数即可得到所需的置信区间。给出置信区间的3项评价指标，通过和其他置信区间评估方法的对比分析可知，算法正确、有效。

Binomial distribution was frequently encountered in various tests. There were many parameter evaluation methods,but the performances were not ideal even in engineering standards. According to discrete characteristics of the binomial distribution,we sug-gested a confidence interval evaluation brute algorithm of binomial distribution parameter p. The algorithm traversed p with fine step,and corrected every confidence interval to adapt to the level of significance. When it traversed all parameters,the confidence interval could be obtained. Three evaluation indicators of confidence interval were provided. Compared with other methods,this algorithm was correct and effective.
