【摘要】：對泥沙縱向相對暴露度的概念進行了修正,通過自行設(shè)計的試驗裝置測量了均勻玻璃球的絕對縱向暴露度,分析計算了縱向相對暴露度及其分布規(guī)律。結(jié)果表明,玻璃球縱向相對暴露度可分為x、y兩個分量,其中:x分量取值區(qū)間為1.0~4.5,服從指數(shù)分布;y分量的取值區(qū)間為-1.5~1.5,近似服從正態(tài)分布。分別給出了x、y分量的邊緣概率密度公式,并利用實測資料對式中的參數(shù)進行了率定,得到縱向相對暴露度的取值區(qū)間為一個3.5×3.0的面域,取值落在該面域內(nèi)各點的概率可以利用給出的縱向相對暴露度邊緣概率密度公式計算得到。
[Abstract]:The concept of longitudinal relative exposure of sediment is modified. The absolute longitudinal exposure of uniform glass sphere is measured by a self-designed experimental device, and the longitudinal relative exposure and its distribution law are analyzed and calculated. The results show that the longitudinal relative exposure of the glass sphere can be divided into x and y components, where the value range of x component is 1.0 鈮，
