| 摘 要： | 对标准圆筒试验技术和相应的底片判读与数据处理方法进行了改进.分析了实验测量和数据处理两方面引入的不确定度,建立了标准圆筒试验测试结果的不确定度评定方法.对直径25 mm标准圆筒试验进行了不确定度评定.结果表明:平均径向膨胀位移和膨胀时间的扩展不确定度(置信度约为0.95)分别约为0.24 mm和0.056μs,拟合曲线的不确定度约为0.014 mm,证明了改进标准圆筒试验和数据处理的精度均较高. |

| Abstract: | The methods of negative interpretation and data processing for the modified standard cylinder test were introduced.The uncertainty origins of test results,mainly from the two aspects of measurement and data processing,were analyzed,and further the uncertainty evaluating method was established.The uncertainties of the modified standard cylinder test in 25 mm diameter were evaluated.Results indicate that the expanded uncertainties of the average displacement in radial direction and the expansion time with the... |
