火工装置抽样方案与接收概率的关系

Relation between Sampling Plan and Acceptance Probability of the Pyrotechnic Device

在一次抽样方案、零失效基础上,采用超几何分布理论推算出火工装置的接收概率方程,并建立抽样特性曲线(OC曲线)模型;分别对百分比抽样、固定数抽样条件下的OC曲线进行讨论,获得了抽样方案与接收概率的对应关系及其规律,为抽样检验工作提供了理论依据。

On the basis of the single sampling plan and zero failure, the acceptance probability equation of pyrotechnic device was calculated, using the hyper geometric distribution theory, and the sampling characteristic curve （OC curve） model was established. The OC curves for percentage sampling and fixed data sampling were discussed, then the corresponding relationship and the law between sampling plan and acceptance probability were obtained. The study provided theoretical support for the sampling inspection.
