記事区分：原著It is very important for the detailed distribution of soil silt particle to realize the state as narrow a range as detectable. The automatic electrical balance can be measured continuously the contents of settling silt particles in soil suspension at a given time. According to the Stokes law, the contents of silt particles corresponding to available size range taken as subdivided range of the silts portion, can be understood as the soil properties themselves. A narrow size range provided reliable data as regards the content of different silt particles. Results were obtained from the charges in increment observed by weighing particles at a given time. Soil silt particle-size distribution characterizes soil according to a range of sizes. There is a need for reliable distribution diagrams with subdivided size ranges. Such detailed diagrams are necessary because of the expression of principal large-size classes such as international division of silt particle. Moreover, such diagrams would benefit studies attempting to describe details about soil texture. Application of this study necessitate understanding physico-chemical, soil genetic and ceramic properties of soil particle ; such an understanding may be enhanced by realistic silt particle-size distribution diagarams.
