摘　　要：分别采用流点法和激光粒度测定法对5%氟虫脲悬浮剂润湿分散剂进行筛选,综合对比2种方法的筛选结果,优选出5%氟虫脲悬浮剂润湿分散剂为GYD08-W10(苯乙烯磺酸盐聚合物-聚氧乙烯氧丙烯醚嵌段共聚物质量比2∶1)。实验结果表明:流点法筛选周期短,操作简单,但结果重复性差;激光粒度测定法实验周期长,仪器昂贵,但结果准确、重复性好。The dispersing agents of flufenoxuron 5% SC was screened respectively by flowing point test and laser granulometry in this paper, finally GYD08-W10（the mass ratio 2：1） was achieved as the excellent dispersing agents of flufenoxuron 5% SC by comprehensively comparing the screening results of two methods. And the results shows that the flowing point test which hae simple operating steps may shorten the screening time, but its results are repeated poorly; laser granulometry has long laboratory cycle and complex operating steps, which needs expensive instrument, but the results of this method are accurate with a good reproducibility.
