摘　　要：针对在导爆索内径尺寸测量中存在由误差引起的被测量真实值难以确定、测量结果存在不确定性这一问题,该文重点从峰值时间和不确定度两个角度出发,改进峰值时间的提取方法,通过分析测量方法,采用不确定度A类和B类评价对相应的参数进行评定,建立数据处理模型,并采用曲线拟合的最小二乘法对结果进行拟合,使结果直观化。实验结果表明:经过该模型处理后的测量结果具有较高的准确度。It is difficult to determine the measuremental uncertainty. This paper mainly evaluation of uncertainty. Through the analysis true value of the detonating cord diameter for focused on the extraction of peak time and the of measurement, Type A and B uncertainties were used to evaluate the corresponding parameters. Then the data processing model was established, and using the least square method of curve fitting to make the results intuitive. The experimental results show that the measurement results have high accuracy after the model orocessing.
