| 摘 要： | 及时准确地了解河流水质状况能更好地对河流水体污染进行控制和治理.利用一维水质模型来近似模拟河水的水质状态.采用有限差分法对模型进行求解,并在求解的过程中对有限差分模型的截断误差进行修正.通过解析解与没有修正的差分解进行对比,结果表明,没有修正的截断误差是不能忽略的.该研究为河流水质污染的防治和预测提供了一种依据. |
| 关 键 词： | 河流水质预测 有限差分 截断误差 误差修正 |

| Abstract: | It is necessary to know the conditions of river water quality in time in order to control and prevent the water pollutions in rivers.A one-dimensional model is used to simulate the river water quality,which is solved by finite difference method.The truncation errors of finite-difference is corrected during solving the model.The comparison between analytical solution and uncorrected solution shows that uncorrected truncation errors can not be ignored.The paper provides a more reasonable approach for the prediction and prevention of river pollution. |
| Keywords: | prediction of river water quality finite-difference truncation error corrected errors |
