粒度分析在沉积物研究中的应用

Application of grain size analysis in sediments research

介绍了粒度分析方法和粒度标准的选取,对粒度分析中样品预处理和测量方法进行了系统阐述,并通过粒度图解法和参数法说明了粒度数据处理中的不同选择,指出了在样品预处理和测量过程中,需特别注意预处理中胶结物的处理方法和样品测试前在粒度仪附件中对样品要进行超声处理,最大限度减少粒度测量中的影响因素;在进行粒度结果整理时,可根据需要,选择不同的粒度图解及粒度参数,或者两种方法综合运用。

The methods of grain size analysis and the selection o{ particle size standard were described. The sample preparation and methods of measurement of grain size analysis system were illustrated systemically. Also, there are different options in treatment of particle size results, including grain size graphic and parameter methods. Especially, in order to minimize the impact factors of particle size measurement, special attention must be paid to the cement processing method in pre-processing and sample ultrasound in laser grain analyzer annex before grain size analysis. In addition, different size illustrations and grain size parameters, or the integrated use of the two methods can be used during particle size results arrangement based on necessity.
