AbstractIt is known that the self-reversal of a prominence line is related to the variation of the source function along the line of sight. In this paper, the variable source function represented by a three-layered model has been used to probe the relation between the changing form of the source function and the self-reversal of the prominence line. It is found that: (1) the source function of self-reversed Ha lines increases from the surface towards the center of the prominence, and the source functions at the center are in theory > 1.0 times those on the boundary of the prominence; (2) when the total optical depth at the line center (taulambda0) is not very thick, the self-reversal cannot appear at the line center, although the source function increases from the surface toward the center of the prominence; and (3) with the increase of taulambda0 and the coefficient of the source function, the profile variations follow this order: shallow self-reversal and then deep self-reversal.
