摘　　要：分析了圆锥外螺纹基面中径的测量不确定度的各种评定方法,在此基础上论述了基面中径测量不确定度的来源、测量方法及计算公式,最后通过实验数据,对基面中径的测量不确定度的评定方法进行了实例分析。结果表明,该评定方法既具有理论意义又具有实际意义。Assessing methods for uncertainty in measurement of cone-shaped thread base level pitch diameter are researched and analyzed,on the basis of which the source,the measurement method and the computing formula of uncertainty in measurement of base level pitch diameter are particularly dissertated. By means of experimental data, the paper analyses assessing method of uncertainty in measurement of cone-shaped thread base level pitch diameter. Researching conclusion indicates that the assessing method is of both integrality and singularity in theory and maneuverability in practice.
