Scientific paper

Using the usual formulation of the mixing-length theory, we have computed solar models with a ratio of the mixing-length to the pressure scale height which varies with the position in the convective envelope. Several functions for that variation have been tested. We find that several of them produce significant improvement of the theoretical frequencies at high orders. The models have also been compared with the seismic model of Dziembowski et al. (1994) and with a function obtained through inversion by Vorontsov et al. (1994). These comparisons have suggested two modifications in the physics of the models which improve the fit with observations.
