| 摘 要： | 研究了可压缩磁化等离子体中,量子效应对瑞利-泰勒(RT)不稳定性的影响.通过对量子磁流体动力学方程的求解,得到描述速度扰动的微分方程.导出了固定边界条件下的RT不稳定性的增长率.研究表明:在可压缩磁化等离子体中,磁场和量子效应都起到致稳RT不稳定性的作用,这与不可压缩磁化等离子体中的结论一致.

| Abstract: | Quantum effects on Rayleigh- Taylor( RT) instability in compressible magnetized plasmas are investigated. By linearly solving the quantum magnetohydrodynamic equations into the normal mode,an ordinary differential equation is obtained to describe the velocity perturbation. Then the growth rate of RT instability is obtained in the presence of fixed boundary conditions. The result shows that the magnetic field and quantum effect have a stabilizing effect on RT instability in compressible magnetized plasmas as in incompressible magnetized plasmas. |
