| 摘 要： | 本文根据常微分方程参数反问题的数学理论，将正交化方法同有限差分法结合用于确定水质模型参数，并与正则化方法、最速下降法和共轭梯度法作了比较。其计算结果对比表明，正交化方法具有快速、简便、可靠的特点。更适合于水质模型参数的确定。

| Abstract: | Orthogonal rule method and finite difference method are combined to calculate the parameters of water quality model based on mathematical theory of inverse problem of ordinary differential equation parameters. And the comparison with positive rule method, gradient descent, and conjugate gradient method is also done. The comparison of the calculation results show that orthogonal rule method is fast, simple and reliable, and is applicable to the calculation of the water quality modeling parameters. |
