摘　　要：SCOPE试验的核心目标是在CAP1400非能动安全壳冷却系统运行参数范围内验证蒸汽/空气混合气体冷凝现象的目标关系式,为安全壳响应分析提供输入。试验结果不确定度分析是试验数据分析的必要步骤,对于评价试验结果的品质具有重要意义。本文采用随机抽样加WILKS公式非参数统计分析方法确定SCOPE试验Sherwood数不确定度区间,为冷凝试验不确定度分析提供了简洁的理论方法。文中介绍的不确定度分析方法可方便地拓展到其他试验数据分析处理中,具有重要的工程应用价值。The purpose of SCOPE test is to verify the steam/air condensation correlation within the parameter variation range of CAP1400 passive containment cooling system.The condensation correlation was used for containment response analysis input.The uncertainty analysis is one important aspect of test data analyses,which is meaningful to the assessment of test results.Nonparametric statistics with WILKS correlation were used to acquire Sherwood number uncertainty.The consistent method for Sherwood number uncertainty analyses was implied in the paper,which may be conveniently applied to the other test data analyses and also valuable to the engineering project.
