| 中文摘要: |
| 为了提高混凝土结构钢筋保护层测定的准确性,采用测量系统分析(ＭＳＡ)技术对钢筋保护层测定仪的分辨力、偏倚、线性以及重复性和再现性等指标进行了系统的试验。分析出仪器变差的主要变异源，判断出仪器存在线性偏倚，在使用中应对数据进行修正，判定仪器可用于结构钢筋保护层厚度的合格评判及施工过程中能力指数的粗略估计。 |
| 英文摘要: |
| In order to improve the testing accuracy for the steel bar position,Measurement Systems Analysis (MSA) technique is used to systematically test the discrimination,bias,linearity,repeatability,reproducibility and other indexes for the TCC determinator.After analysis,we found the source of the determinator variation,and figured out that determinator had linear bias and data correction was necessary during the process.The determinator can be used to judge if the thickness of concrete cover is qualified or not and make a rough estimate for the process capability index during the construction process.? |
