| 摘要: |
| 本文通过对 Brailovskaya 格式的截断误差分析，对该格式作了人工粘性项修正。进行了数值实验，与文献[2]中所研究的几种格式作了比较。说明在计算精度和收敛速度等方面都较原格式为好。
本文通过数值实验，进一步研究了隐式分裂格式，找到了较佳计算参量。 |

| Abstract: |
| The paper made artific viscosity correction through truncation error analysis of Brailovskaya scheme. The numerical test was produced，and its results were compared with the results of other several schemes in 1iterature [2]. The comparison showed that it is better in respects of the calculating precision and velocity.
By means of numerical test，present paper researched further implicit splitting scheme. The better calculating parameter was found. |
