中文摘要：
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。
英文摘要：
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 separatelyby microscopic image analysis method,sedimentation method,laser small-angle forward scattering method, electric-resistivity method and ultrasonic method. The differences among the measuring results were discussed and analyzed. The results showed that they might be attributed to the various principles of the methods. In addition, the samples＇ non-spherical property was an important reason.
