摘要

目前国内外有多种分析仪器可对沉积物粒度成分进行测定，分析结果可能难以对比，在某种程度上影响了研究结论的可靠性。本文详细对比分析了普遍使用的两种激光粒度仪（MS2000和LS13320）对典型的黄土(L

、L

)、古土壤(S

)和古洪水滞流沉积物(SWD)粒度成分的测量结果，结论如下：① 应用MS2000和LS13320激光粒度仪对沉积样品测量结果的重复性都很好，两种仪器得到的粒度分析结果，完全可以作为恢复古环境信息和鉴别地层的一种非常有效的手段。② 对于同一个样品中含量相对较少的细颗粒成分(粘粒、细粉沙)和粗颗粒成分(中沙)，LS13320激光粒度仪的检测效果要优于MS2000激光粒度仪，因此在实际工作中，要注意使用的数据要建立在同一测量系统内，以便进行资料对比。

Abstract

There are many kinds of laser diffraction particle-size analyzers used to study the particle-size of soil sediments in recent years. The analysis results may be difficult to compare

which affects the reliability of the research conclusion to some extent. The particle-sizes of the loess

paleosol and palaeoflood slackwater deposits (SWD) were measured with Mastersizer2000 by Malvern Instruments and LS13320 by Beckm an Coulter. The repeatedly measured results of an individual sample are very good. Both of two analyzers can be used for extracting palaeoenvironmental information of soil sediments. The LS13320 by Beckm an Coulter is better than the Mastersizer2000 by Malvern Instruments in the detective effect of relatively fine and coarse particles with rather few content. Therefore

the particle size of samples should be obtained and analyzed by the same method in order to compare them with different references．
