摘要:
中国北方第四纪风成堆积物的粒度是研究古气候与古环境的一个重要代用指标。粒度测量结果受到前处理方法的深刻影响。在黄土高原西部从北往南5个具有代表性的黄土剖面采集样品25块，对每个样品用不同的前处理方法处理后，用激光粒度仪进行测量。结果显示不同的前处理方法对黄土粒度测量结果会产生很大的影响。原始样品经过超声波振荡和加（NaPO3）6分散剂后，颗粒明显分散变细。在单独加入H2O2除去有机质和加入的HCl除去碳酸盐后，粒度也明显变细，而且南部的样品的差异比北部的要大。在黄土高原北部，石膏对粒度测量的影响较小。
Abstract:
The formation, transport and deposition of aeolian dust are intimately coupled to and indicative of changes in climate and environment. The particle size of loess-palaeosol deposit is regarded as a good proxy record of climate changes in Quaternary in North China, and its grain size distribution is widely employed to reconstruct the palaeoclimate. However, pretreated methods for the grain size measurement are various in laboratories, the pretreated methods have certainly influenced results of grain size distribution. 25 aeolian sediment samples were chosen from five representive sections which are located at a transaction from north to south in the western Chinese Loess Plateau, and each sample is pretreated in seven ways and measured in Mastersizer 2000 produced by Malvern Instruments Ltd. Co. in UK. Result shows that organic carbon and carbonate were removed by treatment with excess H2O2 and HCl and (NaPO3)6 as well as the ultrasonic machine were employed in order to completely disperse the particles, each step can make the particles finer, but the difference is higher in the north sandy loess near the Tengger Desert. The authors also measured the grain size of 102 sandy loess samples in Binggou section near the Tengger Desert. The difference is light after pretreatment of remove the gypsum in the loess.
