摘要

数据分析和理论论证支持色球电流片中的磁重联是观测到的太阳光球磁通量抵消的机制。斯威特·帕克电流片中的磁堆重联可以解释观测到的消磁特性，包括消磁碎片的速度、碎片中的磁通量和从数据推断出的磁通量消率。讨论了如何通过放宽可忽略的电流片曲率和光球上方的重联点高度恒定的假设来建立更现实的色球重联模型。

COMMENTS ON MAGNETIC RECONNECTION MODELS OF CANCELING MAGNETIC FEATURES ON THE SUN

Data analysis and theoretical arguments support magnetic reconnection in a chromospheric current sheet as the mechanism of the observed photospheric magnetic flux cancellation on the Sun. Flux pile-up reconnection in a Sweet{Parker current sheet can explain the observed properties of canceling magnetic features, including the speeds of canceling magnetic fragments, the magnetic uxes in the fragments, and the flux cancellation rates, inferred from the data. It is discussed how more realistic chromospheric reconnection models can be developed by relaxing the assumptions of a negligible current sheet curvature and a constant height of the reconnection site above the photosphere.
