摘　　要：采用GB/T601-2002标准配制并标定盐酸标准溶液浓度,并分析盐酸标准溶液配制及标定过程中相关参数对浓度的不确定度影响。结果表明,盐酸标准溶液浓度的相对扩展不确定度为2.1×10-4。The standard solution of hydrochloric acid was prepared and standardized with GB/T601-2002 method. Effects of related parameters in the process of preparation and standardization of hydrochloric acid standard solution on the uncertainty of the concentration were analyzed. The results show that the related expanded uncertainty is 2.1 ×10-4.
