球形金属罐容量测量结果不确定度的评定

球形金属罐容量测量结果不确定度的评定
陈漫雪汕头市质量计量监督检测所,广东汕头515041摘　要:依据JJC642-1990《球形金属罐容量国家计量检定规程》和JJF1059-1999（测量不确定度评定与表示国家计量技术规范》，对环形金属罐容量的测量结果不确定度进行评定。环形金属罐的测量采用光切法，通过分析中心距、水平夹角、左右切点天顶距等参数，计算球形金属罐容量测量结果的不确定度。可供从事球形罐检测工作的人员参考。[著者文摘]

Evaluation of uncertainty in measuremen for capacity of spherical metal tankCHEN Man-xue Shantou Institute of Supervision and Test of Quality and Metrology, Shantou 515041, ChinaAbstract:This article evaluates the uncertainty of measurement results of measuring spherical metal tank capacity in accordance with JJG642-1990 V.R. of spherical metal tank capacity and JJF1059-1999 evaluation and expression of uncertainty in measurement. Spherical metal tank is measured by light tangent method, and the uncertainty of measurement results is calculated by analysing the centre distance,horizontal angle and left and right tangent distance to the top etc.This article could be a reference for people who is at working on measuring spherical metal tank capacity.[著者文摘]
