假设检验在建设工程实验室管理中的应用

为了评估同一实验在不同操作过程中是否有本质的差别,以采集耐碱玻璃纤维网布经向和纬向的初始拉伸断裂强力实验为例,提出应用假设检验的方法进行量化分析。采用正态P-P图、Kolmogorov-Smirnov单样本检验法、两个独立样本Mann-Whitney检验法、游程检验法进行对比实验。研究结果表明,可以用假设检验的方法来量化分析实验过程是否有本质的差别;通过多角度对实验数据的量化分析,可以评定实验操作过程对实验结果影响有无显著性差异,评定实验数据采集过程是否出现异常。

The application of hypothesis testing on the construction engineering laboratory management

For different analysts or different laboratories using the same analytic methods, or a analyst from same laboratory using a variety of different principles of analytic methods, the method of hypothesis testing can be applied to quantitative analysis, to assess whether there are essentially differences in their experimental process. Research methods adopt normal P-P diagram, Kolmogorov-Smirnov one-sample test method, two independent samples Mann-Whitney test method, Runs test method. The initial tensile strength data from longitude direction and latitude direction of Alkali-resistant glass fiber mesh will be collected by experiment. The research results show that the quantitative analysis of experimental data through multi-angle can be used to evaluate whether the experimental operation have a significant difference on the experimental results. Thus laboratory management can be promoted through quantitative analysis of experimental data.
