摘要
绝对隐蔽度和相对隐蔽度是泥沙颗粒隐蔽度研究中的2大派别。针对韩其为定义的二维泥沙颗粒相对隐蔽度,给出了统计意义上的宽级配非均匀沙颗粒相对隐蔽度的计算式,对该式的物理意义进行了讨论,并提出了基于泥沙相对隐蔽度的宽级配非均匀沙中"大颗粒"、"小颗粒"、"中等颗粒"的概念。
There are two different schools to study the hidden degree of sediment parhcles: at)solute mooen aegree and relative hidden degree. The 2-D relative hidden degree of sediment particles defined by Han Qi-wei was elaborated in this paper. The hidden degree formula of wide grain size distribution of non-uniform sediment was deduced statistically. Relevant discussions on the physical significance of the formula were presented, and the concepts of "large grain" , "small grain" and "medium grain" associated with broadly graded non-uniform sediment were proposed as well.
