【摘要】:对泥沙纵向相对暴露度的概念进行了修正,通过自行设计的试验装置测量了均匀玻璃球的绝对纵向暴露度,分析计算了纵向相对暴露度及其分布规律。结果表明,玻璃球纵向相对暴露度可分为x、y两个分量,其中:x分量取值区间为1.0~4.5,服从指数分布;y分量的取值区间为-1.5~1.5,近似服从正态分布。分别给出了x、y分量的边缘概率密度公式,并利用实测资料对式中的参数进行了率定,得到纵向相对暴露度的取值区间为一个3.5×3.0的面域,取值落在该面域内各点的概率可以利用给出的纵向相对暴露度边缘概率密度公式计算得到。
[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,
