摘　　要：渗流系统的灰色数值模型是借助灰色系统理论的基本思想、基于灰朦胧集基础建立的。该模型输出结果——水位灰度能否在一个较小的、实用的范围内变化,是模型应用中十分关注的问题。在给出渗流系统灰色数值模型的基础上,通过算例,分析当模型的输入信息(包括导水系数、储水系数、入渗水量)取不同的灰度时,模型的输出结果——水位灰度将出现如何的变化。分析结果表明:输出水位灰度随着输入信息灰度的变化呈线性或非线性关系。因此,模型实际应用中,为了使模型计算得到的灰水位灰度在一定的范围,应当尽量减小各个输入信息的灰度。The build of grey numerical model of seepage system is based on grey system theory, grey hazy set foundation. It is a great concerned problem in model application whether the grey degree of water level outputted from the model ranges at a smaller, practical space. The article is based on the given model to analyze how increases the gre？ degree of water level with the increase of grey degree of input information （ including hydraulic conductivity coefficient, storage coefficient and water in- flow） by a case. The result show that the grey degree of water level changes with the grey degree of input information in a line- ar or nonlinear relationship. Therefore, the grey degrees of various input information should be controlled at a smaller space to obtain less grey degree of water level in practical application of the model.
