摘要
GB/T 6378.4—2008是平均值的计量监督检验标准,其中表4的抽样方案是近似的(正态近似)。本文采用'学生't分布的理论,改进了平均值的计量监督检验抽样方案表。
GB/T 6378.4-2008 is the standard for metrology, supervisory and inspection by variables for mean value. The sampling plan in table 4 was approximation. The article adopts the central t distribution theory and tries to improve the sampling plan in table 4 for metrology, supervisory and inspection by variables for mean value.
