河流水质数学模型中的参数是反映污染物在水体中进行演化的一个物理量,是河流水体的物理、生物和化学反应动力学过程的一个常数。水质模型中的参数对水质模型的合理性和可靠性有重要的影响,长期以来人们对参数已有相当广泛的研究,并提出许多方法。本文仅对参数中降解系数K_1(以下简用K)的计算方法进行一些讨论,并提出一种新的简便的优化方法。
The parameters in the mathematical model of river water quality is a physical quantity that reflects the evolution of pollutants in the water body, and it is a constant of the physical, biological, and chemical reaction kinetic processes of river water bodies. The parameters in the water quality model have an important influence on the rationality and reliability of the water quality model. For a long time people have studied the parameters quite extensively and proposed many methods. This article only discusses the calculation method of the degradation coefficient K_1 in the parameters (the following simple K), and proposes a new simple optimization method.
