英文摘要: Using the two fluid model, the problem of two-dimensional steady-state magnetic reconnection in incompressible resistive weakly ionized plasmas is analysed. Under the strong-coupling condition such as in the Sun's photosphere, it allows us to express the current sheet analytically. In this case the current sheet scales as eta (1/2). Then this model is used to understand magnetic flux cancellation which is observed in the Sun's magnetograms. To account for a cancelling flux of 1 x 10(8) Max in a time interval of 77 min, the width of the current sheet is about ten kilometres.
