采用统计控制图法评定水泥烧失量的不确定度

摘要

Through applying Top-down statistical control chart method,combining with daily accumulated data,the paper discusses common measurement system control condition,applies t examination methods,and finds out that:it assesses the measurement uncertainty of cement LOI without considering system errors,comparing to traditional bottom-up method,it is relatively easy for operation,avoids components missing and repeatedly components,and achieves more objective results as well.%采用Top-down法之统计控制图法，结合日常积累数据，在论证日常测量系统过程受控，并通过t检验表明系统误差可以忽略不计情况下，评定了水泥中烧失量的测量不确定度，相比传统的bottom-up法，相对简易且操作性强，同时也避免了分量的遗漏及重叠分量，使得到的结果更加客观。
