应用等离子体一维输运模型与撕裂模理论,对于不同的输运模型及托卡马克放电参数下撕裂模的演变进行了数值的研究。结果表明成量过程是影响等离子体宏观稳定性行为的一个不可低估的重要因素。它们与磁流体稳定性的相互影响,会使其磁流体形态构成多种时间或空间结构;等离子体温度、密度等宏观参量也将表现出不同的时空特征。
Using the plasma one-dimensional transport model and tear-off theory, the numerical study of the evolution of tear modes under different transport models and tokamak discharge parameters was carried out. The results show that the formation process is one of the most important factors that can affect the macroscopic stability of the plasma. Their interaction with the stability of the magnetic fluid will make its magnetic fluid form a variety of time or space structure; plasma temperature, density and other macro parameters will also show different spatio-temporal characteristics.
