摘　　要：对于大型水力管网，用线性方程组解算时，由于系数矩阵为稀疏矩阵，直接解算要占用大量计算机内存，而利用稀疏矩阵技术能大大减少内存，从而提高运算速度。本文详细论述了此技术在水力管网解算中的具体方法及程序实现。In regard of a large scale and heavy hydro junction pipenet when being calculated with linear equations combination, and owing to the matrix of coefficients being sparse matrix which will take a large number of computers inner stores. However, the technique of the sparse matrix used can reduce the inner stores to a large extent, so that the computation speed will greatly improved. The paper deals with, in detail, this technique involving in concret methods and programs having been carried out in the computation of the heavy hydro junction pipenet.
