Solar filaments are an intriguing phenomenon, like cool clouds suspended in the hot corona. Similar structures exist in the intergalactic medium as well. Despite being a long-studied topic, solar filaments have continually attracted intensive attention because of their link to the coronal heating, coronal seismology, solar flares, and coronal mass ejections (CMEs). In this review paper, by combing through the solar filament-related work done in the past decade, we discuss several controversial topics, such as the fine structures, dynamics, magnetic configurations, and helicity of filaments. With high-resolution and high-sensitivity observations, combined with numerical simulations, it is expected that resolving these disputes will definitely lead to a huge leap in understanding the physics related to solar filaments, and even shed light on galactic filaments.

近十年来太阳能灯丝研究引发的一些有趣话题

太阳丝是一种有趣的现象，就像悬浮在炽热日冕中的冷云一样。类似的结构也存在于星际介质中。尽管是一个长期研究的课题，但太阳丝因其与日冕加热、日冕地震学、太阳耀斑和日冕物质抛射 (CME) 的联系而不断受到关注。在这篇综述论文中，通过梳理过去十年中与太阳能灯丝相关的工作，我们讨论了几个有争议的话题，例如灯丝的精细结构、动力学、磁构型和螺旋度。通过高分辨率、高灵敏度的观测，结合数值模拟，预计解决这些争议必将导致对太阳丝相关物理理解的巨大飞跃，
