中文摘要：
根据西安市给水管网压力监测点的实际运行数据,综合利用变量相关系数和变量标准差等信息,选择测压点。结合西安市给水管网现状,通过统计回归方法得出符合该市给水管网工况的宏观模型,并用实际运行数据进行了验证。结果表明,该模型基本反映了该市给水管网的供水量与水压关系,为优化调度各水厂的供水量创造了条件。
英文摘要：
According to the service data of pressure tap＇ data, the macroscopic model of water distribution system in Xi＇ an.was founded by means of statistical regression analysis,which was based on present status of water distribution system and pressure tap＇s data which was selected by integrated utilization of correlative variable coefficient and variable standard deviation of pressttre tap＇s data. On the whole, the model, which was the base to schedule the water supply of every water plant, can reflect relation of the quantum of water supply and hydraulic pressure.
