【正文】 ,同時應(yīng)有檢驗人員、技術(shù)負(fù)責(zé)人或用戶代表在場，監(jiān)督工序按規(guī)定的程序和要求進(jìn)行。 檢查內(nèi)容： 圖紙、技術(shù)文件是否正確、完整 檢驗結(jié)果是否正確 有關(guān)技術(shù)或質(zhì)量問題的處理是否合適 追溯制 在生產(chǎn)過程中，每完成一個工序或工作，都要記錄檢驗結(jié)果及其存在問題，在產(chǎn)品的適當(dāng)部位做出相應(yīng)的質(zhì)量狀態(tài)標(biāo)志。共抽取考卷 100份，重新判分的結(jié)果是：及格 88人，不及格 12人。 漏檢率 ： 9/96 = % 錯檢率 ： 1/4 = 25% 抽樣檢驗 抽樣方法 抽樣檢驗分類 計數(shù)抽樣檢驗方案 抽樣方法 無偏好原則： 應(yīng)用隨即抽樣來抽取樣本 簡單隨機(jī)抽樣 指從一批產(chǎn)品（ N件 ）中 任意地 抽取n件 （每一件產(chǎn)品被抽取的可能性是相等的） 例如 ： 摸獎（獎盒密閉，獎票特性相同） 搖獎（機(jī)械操作，獎球特性相同） ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ● 系統(tǒng)抽樣 每隔一段時間或一定編號進(jìn)行，而每一次又是從一定時間間隔生產(chǎn)出的產(chǎn)品或一段序號產(chǎn)品中任意抽取樣本。用 抽取樣本的連續(xù)尺度 定量地衡量一批產(chǎn)品質(zhì)量的方法稱為計量型抽樣檢
