中文摘要: |
Dobbins模型是水质模拟和水质规划中经常使用的BOD-DO耦合模型。本文即以此模型为基础,依据数学物理反问题理论,构造了BOD-DO耦合模型有关分布参数的反演问题。并与复合形优选方法进行对比,证明了本文提出的水质参数FR反演辨识方法的有效性和避免多参数时维灾问题,为水环境参数提供了新的方法和思路。 |
英文摘要: |
Based on the principle for reverse problem, the Frechet-Regular method is introduced to deduce the algorithm for solving the distribution parameters of Dobbins model, which is a BOD-DO coupled model used in simulation of environmental water quality. The effectiveness of the proposed method is verified by comparison with traditional method. By using this method the curse of dimensionality probably occurred to multiple parameters problems can be avoided. |
