| 摘要: |
| 本文得出了双绝热近似的磁流体力学能量积分关系式。分析表明这种磁流体力学系统是保守的，可以采用运动方程或能量原理方法分析系统的稳定性特性。本文从控制方程组出发讨论了线性稳定性的基本原理，指出纵向压力增值有助于系统的稳定性。 |

| Abstract: |
| This paper has given magneto-hydrodynamic energy integration relationship at the condition of biadiabatical approximaticn. Analysis shows that magneto-hydrodynamic system of this kind is conservative. It is feasible to adopt kinetic equations or method of energy principle to analyze the systematic stability. This paper has discussed the basic principle of linear stability proceed from governing equations，and has showed that increment of longitudnal pressure is benifit to systematic stability. |
