| 摘要: |
| 本文用解析分析的方法分析了等离子体粒子模拟中的有限大小粒子、电荷近网格分配和时间差分方法引起的相对于等离子体静电波色散关系的偏离，导出了修正后的色散关系。文中设计了等离子体粒子模拟的计算机模拟实验方案，验证了有限大小粒子和时间差分方法引起的对于色散关系的偏离；介绍了用不同大小粒子进行孤立子现象的等离子体模拟，结果表明，粒子的大小不同可产生相反的结果。 |

| Abstract: |
| A theoretical model is made to analyse the effects of finite-size particle，charge nearest grid sharing and time difference on the electrostatic dispersion relation of plasma. A modified dispersion relation is derived. The computer experimental scheme to simulate the plasma particle is designed. The simulation result shows the effects of finite-size particle and time difference on dispersion relation. Finally，completely different simulation results of plasma soliton with different particle size are presented. It indicates that these effects may change the basic physical phenomena of the simulated results in some circumstances. |
