基于Bayes方法的节水灌溉产品质量抽样检验方案研究（Study and Application on Sampling Test Plan of Water-saving Irrigation Products Based on Bayes Method）
节水灌溉 产品质量 抽样检验 Bayes方法
2010/4/1
利用节水灌溉产品质量抽样检验先期数据和经验，构建基于Bayes方法的节水灌溉产品质量抽样检验方案，利用该方案对塑料管材和滴灌灌水器以及旋转式喷头进行产品质量检验的新样本抽样。结果表明，产品检验样本量降低率E主要与先验产品合格率方差S2R和先验产品合格率均值Ra有关，对小于1200的常用产品批量，S2R=0.002和Ra=0.95下的塑料管材和滴灌灌水器以及旋转式喷头的产品检验样本量降低率分别高于6...
