| 摘要: |
| 运用待定系数法，对Holly-Preissmann格式进行了改进，补充了流速为负时的Holly-Preissmann格式，并在此基础上建立了保守型对流方程的数值格式。新建格式的计算结果与理论解吻合较好，且实用。 |

| Abstract: |
| Holly Preissmann scheme is improved and the scheme used for the minus velocity is added by use of the undetermined coefficient method. Based on the above, a new numerical scheme for the conservative convection equation is developed. Calculation results of the new scheme are found agreeable with the exact results. So the scheme is practical. |
| Key words: Holly Preissmann scheme,conservative convection equation,numerical scheme,undetermined coefficient method |
