摘要
以函数逼近和Tikhonov正则化为基础,利用算子识别摄动法、线性化技术,建立了河流水质纵向弥散系数反问题的迭代算法,并给出了计算实例,其结果表明,该方法具有数值精度高,稳定性好,收敛速度快,整个参数反演过程可以程序化,由计算机完成等优点。值得在实际工作中采用。
A new iterative computational method of the inverse problem for the determination of the longitudinal dispersion coefficient in water quality model is introduced. The method is based on the approximation of function, Tikhonov regularization and optimal perturbation. Example of numerical computation is offered. The numerical results show that the method has higher numerical precision, convergence rate and stability. It is worthy of practical application.
