摘要
介绍了气体标准物质标称值测量的应用领域和测量结果的重要性。通过对气体标准物质样品标称值的测量和标称值的结果评价,着重描述了气体标准物质标称值两种测量方式的不确定度评定方法。明确了气体标准物质标称值的量值溯源路径,有效提升了气体标准物质使用和测量过程中不确定度评定的规范性。
The application field of nominal value measurement of gas reference materials and the importance of measurement results were introduced.Through the measurement of the nominal value of the gas reference material sample and the evaluation of the results of the nominal value,the uncertainty evaluation methods of two measurement methods of nominal value of gas reference materials were emphatically described.The traceability path of nominal value of gas reference materials was clarified.The content of essay effectively improved the standardization of uncertainty evaluation in the use and measurement process of gas reference materials.
