摘　　要：论述了基于ARM的断面测定仪的软件,并利用所建立的模拟巷道断面,对模拟断面进行了多次重复测试,用A类不确定度评定方法,给出了巷道断面测量结果的不确定度评定和分析。测试结果表明:面积和周长均具有很高的精度,且面积的精度更高。指出了面积和周长精度差别产生的可能原因和修改方法。In the paper,the author demonstrates the software of the tunnel section measurement instrument based on ARM,uses the simulation tunnel section to measure repeatedly and gives the uncertainty evaluation and the analysis of tunnel section measurement results using the uncertainty evaluation method of the Class A.The results demonstrate that the accuracy of area measurement than perimeter measurement are higher,and the accuracy of area measurement is higher.The author points out the possible reasons and the modify method for the difference accuracy between area measurement and perimeter measurement.
