摘　　要：运用概率统计方法,分析在铁路计量中,使用双向误差计量标准器量值传递单向允许误差被检计量器具时,测量结果不确定度和待定区间及误判概率的关系。在运用蒙特卡洛法不确定度评定软件加以验证后,提出降低误判的剔除待定区间法、标准器修正法、提高测量准确度法3种方法,从而保障铁路在用计量器具的量值准确可靠。By using probability statistics, the article analyzes the relationship of uncertainty in measurement results, pending interval and error probability when using two-way error to measure the tested measuring instrument with one-way permissible error in standard measurement value transmission in terms of railway metrology. Upon verification via the uncertainty evaluation software based on the Monte Carlo method , the article proposes 3 methods to lower errors, namely, pending interval elimination, standard correction and measurement accuracy improvement, thus guaranteeing the accuracy and reliability of measurement values for measuring instrument used for railway.
