摘    要:为了比较不同粒度测试方法测量同一样品的结果差异,本文中采用500目筛网过筛后的黄河泥沙作为测量样品,分别采用显微镜图像法、沉降法、小角前向散射法、电阻法、超声法对其进行了测量,分析了不同测量方法结果之间的差异。结果表明,测量原理和分析手段是带来测试结果差异的主要原因,此外泥沙颗粒形状的不规则性也带来较大影响。

关 键 词:河流泥沙  颗粒  粒度分布

Abstract:Aimed to compare the discrepancies of measurement results by different particle size analysis methods,the sediments from the Yellow River which were sifted through a 500 mesh sieve were measured separate-ly by microscopic image analysis method,sedimentation method,laser small-angle forward scattering method,electric-resistivity method and ul-trasonic method.The differences among the measuring results were dis-cussed and analyzed.The results showed that they might be attributed to the various principles of the methods.In addition,the samples' non-spheri-cal property was an important reason.
Keywords:sediment of river  particle  size distribution
