由于评估产品可靠度时存在样本量不足的问题,常常需要利用环境因子将不同环境下的试验信息折算为同种环境下的试验信息,传统基于预计技术的环境因子研究方法存在数据不完整、估计不精确的问题.针对上述问题,提出了一种基于统计推断思路的不同环境下二项分布试验数据的环境因子区间估计方法,并结合计算实例与已有方法进行了比较,结果表明,该方法计算简便,能较好地反应出不同环境间的差异性,能较好地满足工程实践需要,与已有方法相比具有一定的优越性.%Due to the lack of sample amount when assessing product reliability,it is often necessary to use environmen-tal factors to convert test information in unused environment into test information in the same environment.For the tradi-tional research methods based on the predicted environmental factors,problems of incomplete data and inaccurate estimation exist.In this paper,an interval estimation method for environmental factors of binomial distribution test data under different environments based on statistical inference is proposed,compared with the calculation examples and previous methods.The results show that the method is simple and it can reflect the difference between different environments,well meeting the needs of engineering practice.In all,this method has preference comparing with other methods.
