The article analyzes the research findings home and abroad on the coefficient of variation per hours. And it indicate scientifical determination about use of water by various types of water users is profound for the formation and perfection of fixed hot water supply and the coefficient of variation per hours suited to China's.【中文關鍵詞】 生活給水; 小時變化系數; 設計流量【英文關鍵詞】 water supply; the coefficient of variation per hours; design flow
