摘　　要：介绍了一种城市输配水系统漏失水量的检测分析方法.通过在同一时刻抄读输配水系统的供水端和城市样本用户端的计量装置的数据,分析了城市输配水系统的用水和供水变化规律,并通过确定城市"最小用水时",分析该时刻供水量和用水量之间的数量关系,计算得到该时刻漏失水量,同时考虑水压、仪表精度等因素的影响,修正该计算值,从而得到城市输配水系统的漏失水量或漏失率.该方法适用于城市输配水系统的供水端和用户端安装有较完善的计量装置情况下的漏水量检测.A new method stemmed from the traditional leakage detection is introduced. This method is to register the datum of the water meters installed on the water supply and the users at the same time in order to know the regularity of the water supply and the water consumption. The time for minimal datum of the city water consumption can be determined and the amount of leakage of the city from the exemplar can be known. This method will be affected by such factors as the rate of water meter installed on the water supply and the users and the precision of the water meter. This method strengthens the theory of water supply engineering.
