标题： Standing MHD Waves in a Magnetic Slab Embedded in an Asymmetric Magnetic Plasma Environment: Surface Waves

摘要： 在先前一项分析磁性薄板中表面波的研究基础上，本研究对该模型进行了推广，并加入了外部磁场。 假设薄板较薄，且磁性不对称性较弱。 导出了驻波谐波模式的频率，以表示薄板宽度和弱不对称性的少量量作为主要阶数。 发现频率更容易受到薄板宽度变化的影响，而不是磁性不对称性的变化。 导出了第一谐波与基模的频率比，以及薄板两侧的振幅差，因为这些可能是可观测的量，可以与观测结果进行比较，并用于进行太阳磁流体力学诊断。 显示英文摘要

摘要： Building on a previous study that analyses surface waves in magnetic slabs embedded in a non-magnetic external environment, in this study the model is generalised and external magnetic fields are added. The slab is assumed to be thin, with weak magnetic asymmetry. The frequencies of the standing harmonic modes are derived to leading-order in the small quantities representing the thin slab width and the weak asymmetry. It is found that the frequencies are more prone to changes to the width of the slab than changes in the magnetic asymmetry. The frequency ratio of the first harmonic to the fundamental mode is derived, along with the amplitude difference between the two sides of the slab, as these may be observable quantities that can be compared with observational results and applied to carry out solar magneto-seismology.
