| 摘 要： | 在泰勒级数分析的基础上,对一维地下水污染的灰色模型求解过程中有限差分法的截断误差进行了修正,得到了修正后的灰色有限差分解.通过与解析解和没有修正的灰色解进行对比,表明没有修正的截断误差是不能忽略的.修正后的灰色数值解的灰带更窄而且更加合理.图1,参8. |
| 关 键 词： | 地下水污染 截断误差 有限差分 修正 灰带 |

| Abstract: | In order to study the groundwater pollution well, truncation errors associated with gray finite-difference solution of one-dimensional groundwater pollution were corrected based on the Taylor analysis. Thus a corrected gray finite difference solution was got. Comparison with the analytical solution and uncorrected solution, uncorrected truncation errors can not be negligible and the gray scope of corrected gray numerical solution becomes more little and reasonable. 1 fig., 8refs. |
| Keywords: | groundwater pollution truncation error finite difference correction grey scope |
