Solar pores are transient dark spots in the continuum images of the Sun. Their dynamics are closely associated with solar magnetic fields and plasma motion. Their motions have been found to be correlated with their magnetic pressure differences. This work is aimed to investigate possible reasons for this correlation. Our examination of 19 pairs of bipolar pores reveals a magnetic pressure difference rule between the pores of a same pair: their signs of the differences between the magnetic pressures at the front and back sides are always opposite, and their directions of the maximum positive difference between the magnetic pressures at the opposite ends are always both pointing toward the left or right and are always slightly toward the higher latitudes. The rule indicates that the properties of the bipolar pores are influenced by the solar global magnetic fields and rotation.

移动双极孔的磁压差规则


太阳孔隙是太阳连续图像中的瞬态黑点。它们的动力学与太阳磁场和等离子体运动密切相关。已发现它们的运动与它们的磁压差相关。这项工作旨在调查这种相关性的可能原因。我们对 19 对双极孔的检查揭示了同一对孔之间的磁压差规则：它们前后磁压差的符号总是相反的，它们对端磁压之间最大正差的方向总是指向左侧或右侧，并且总是略微偏向较高的纬度。该规则表明双极孔的特性受太阳全球磁场和旋转的影响。
