沉积物样品的分选性、偏度和中值粒径之间存在着物理联系。对沉积物输移和沉积过程中流体力学原理的研究表明，影响沉积物输移和沉积的主要因素有三个：海底粗糙度、沉速和起动流速。根据这些控制因素对沉积过程的分析表明，分选和偏度与沉积物中值直径的关系可能为沉积物的搬运和沉积条件提供线索。
ABSTRACT Observations show that a physical relationship exists between the sorting, skewness and median diameters of sediment samples. Investigation of the fluid mechanic principles involved in the transportation and deposition of sediments indicates that there are three primary controlling factors; the degree of bottom roughness, the settling velocity, and the threshold velocity. Analysis of sedimentary processes in the light of these controlling factors indicates that the relationship of sorting and skewness to the median diameter of a sediment may furnish a clue to the conditions under which the sediment was transported and deposited.
