【摘要】 针对多孔介质中污染物运移的不确定性问题,将地下水渗流流速和弥散系数等视为未确知参量,并以灰参数的形式表示,运用灰色理论建立了地下水水质模拟的灰色数学模型。该模型具有一种特殊的结构,并且给出了求解这类模型的灰色数值算法。通过实例表明,该方法是可行的,模拟结果是合理的。更多还原

【Abstract】 In view of the uncertainty problem of contaminant transport in porous media,seepage velocity and dispersion coefficient are considered as uncertainty parameters and expressed as gray parameters.One dimensional gray numerical groundwater quality model is built according to gray theory.The model has an especial structure and the gray numerical arithmetic to solve this kind model is given.The result shows that the arithmetic is feasible and reliable to simulate water quality.更多还原
