摘　　要： 回顾了30多年来,国外研究者在下水道污水复氧能力测定与复氧系数估算模式方面的实验手段、理论分析方法与研究成果,介绍多种下水道复氧系数估算模式并分析了各自的优缺点,为国内的下水道污水自净机制研究提供了一些参考。 The studies of re_aeration in sanitary gravity sewers in recent three decades around the world were re- viewed. The methods of re.aeration rate determination, the theories of oxygen transfer between air to water, and the models predicting reaeration coefficient were introduced. The advantages and disadvantages of these studies were also analyzed.
