摘　　要：提出一种对两类配水管网基础方程分别处理,管段流量和节点水压同步校正的管网平差方法。该方法无需初始分配流量,不计闭合环信息,求解过程简单,收敛性好。计算初始假定流向,使得利用计算机进行管网水力计算更加方便易行。据此编写了电算程序,并通过多水源供水管网水力计算实例验证其可行性及精确性。A new arithmetic for hydraulic computation of water distribution network, in which the two kinds of the basic equations are treated respectively and the node head and pipe flow are adjusted synchronously, is put forward in this paper. This method need not distribute flow initially and consider loops information and has perfect astringency and simple equations. It is more convenient to do the hydraulic computation by computer after initial flow direction is assumed. Based on this, the computer software is programmed and its feasibility and accuracy are verified through the hydraulic computation of a multi-source water supply network sampl
