沥青混合料沥青含量抽样检测的样本检测值服从正态分布。平均值的t检验可以评定搅拌设备的配料计量准确度 ,方差的卡方检验可以评定搅拌设备的配料稳定性及搅拌均匀性 ,本文对此举例予以说明。
Asphalt mixture asphalt content of the sample test values ?? tested obey the normal distribution. The t-test of the average value can be used to evaluate the accuracy of the ingredients of the mixing equipment. The chi-square test of variance can evaluate the ingredients stability and mixing uniformity of the mixing equipment. This article illustrates this example.
