| 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。

| Abstract: | There are two different schools to study the hidden degree of sediment particles: absolute hidden degree 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 gra... |

| Keywords: | relative hidden degree uniform distribution uniform sediment non-uniform sediment |
