The Establishment of Linear Algebraic Equation with Node Multivalued Method of Boundary Ele-ment Calculating Groundwater Flow Problem

给出了利用节点多值法处理边界奇点时，建立边界元线性代数方程组的公式，从而为边界元线性代数方程组的自动建立和求解奠定了理论基础。

This paper puts forward the formula of establishing boundary clement linear algebraic equation when the node multivalued method is used to manage boundary singularitynode.The formula is the theoretic basis auto-establishment and auto-soiution of boundary linear algebraic equation.
