摘　　要：标准表法流量标准装置以标准流量计为主标准,其标准流量计系数修正的方式是否合适,直接关系到整个流量标准装置的不确定度等级。常用的系数修正方法有AB值法、定点法、分段修正法等,文章通过理论数学模型分析和具体的算法实现,再结合实际的现场实验数据,总结出各种修正算法的优缺点,以便使用标准表法流量标准装置的检定员更好的理解装置特性,在不同的使用环境中选择合理的标准流量计系数修正方法。The standard meter method flow standard device is mainly based on the standard flow meter,and whether the coefficient correction method of the standard flow meter is appropriate directly affects the uncertainty level of the entire flow standard device.The commonly used coefficient correction methods include AB value method,fixed-point method,segmented correction method,etc.Here,through theoretical mathematical model analysis and specific algorithm implementation,combined with actual on-site experimental data,the advantages and disadvantages of various correction algorithms are summarized,so that the calibrator of the flow standard device using the standard meter method can better understand the characteristics of the device and choose a reasonable standard flow meter coefficient correction method in different usage environments.
