摘要
SOD是影响水中溶解氧的重要因素。本文论述了底泥的特征,建立了沱江底泥耗氧的多元线性回归模型和再悬浮SOD模型.并讨论了影响底泥耗氧的主要因素。本研究发现底泥耗氧率模式为R=a exp(b/D)(a=3499.3,6=-0.192)。
SOD is an important factor to impact on DO levels in waters. This paper has described the characteristics of sediments, and established a multi-linear and progressive regression model of oxygen consumption of bottom mads, and refloated SOD model in the Tuojiang river. The primary factors, impacting on sediment oxygen demand have been discussed in detail. In these researches, it was found that the SOD rate was governed by the function R=a exp(b/D)(a=3499.3, b=-0.192).
