| 摘 要： | 在W.J.Padgett等对随机水质模型研究的基础上,本文以样本资料为重要信息,直接推求BOD和DO的联合分布函数。以此为基础,结合地面水水质标准,推出BOD-DO的耦合达标率公式,同时结合Dobbins模型导出了上游断面的BOD-DO概率边界值计算式。以沱江流域顺河场至中瓷厂水质资料作为实例进行计算,结果表明模型有广阔应用前景。

| Abstract: | From the point of view that two variables are of a common joint probability density function suggested by Cacoullos. T, this paper infers a stochastic water quality model on the river with the law of decomposition, and it also makes a thorough and careful study on application in water pollutant control. This paper takes the calculation of the water quality index between two sections(Su-he-chang and Zi-zhong in Tuo river) as an example of the concrete application of the suggested model. |
