【摘要】 鉴于变异函数的优点,引用了L.Smith自回归过程随机模拟开度的方法,使研究区域的开度满足对数正态分布.利用对数正态分布密度函数的两个参量形成不同的开度,在此基础上从流量、纵向弥散系数及滞留时间三方面来研究开度对水流和溶质运移的影响.更多还原

【Abstract】 Based on the advantages of the variogram, the autoregression process for aperture simulation developed by L. Smith is adopted for solution of the aperture of single fissures, which accords with the log-normal distribution. Different apertures are formed with the two parameters of the log-normal density function, and the effects of the aperture on water flow and solute transport are studied from the angles of flow rate, longitudinal dispersivity, and retention time.更多还原
