摘要：

Twenty representative samples were collected from the Chinese loess plateau and each sample was prepared in 6 different ways respectively in order to test the influences of pretreated methods on grain size measurement. The results show that (i) different pretreated methods can make a big difference for the samples granulometry; (ii) soaking in distilled water for one day, and then treating with an ultrasonic machine for 10 min can make the sample dispersed.
