| 摘 要： | 针对某些地质条件导出了离散双重介质二维二相流耦合微分方程，对方程中的渗透率和裂隙宽度进行了Karhunen－Loeve级数展开，对其他参数进行了多项式随机函数的级数展开，同时对截取级数前有限项所产生的误差作了分析．在求解基本未知量的同时也能求解随机变量的特征数。

| Abstract: | The paper gives the coupling part differential equation system about ZD two--phase flow in discrete media under certain assumption. The permeabilities and fracture apertures in the equations are expanded into Karhunen-Loeve series. Other parameters are expanded into polynomial series of stochastic functions. The errors caused by the series trimming are analyzed.The eigenvalues of random variables can be solved when the basic unknowns are solved. |
