- Аннотация: UBVRI photometry and spectroscopic observations around the H-alpha line of the cataclysmic star UX UMa are presented. The analysis of the 9-year photometry shows that the out-of-eclipse brightness of the system and the depth of the eclipse changes in different time scales while the width of the eclipse remains constant. The observed features of the light curves as well as the features of the two-peaked H-alpha profiles were attributed to an inhomogeneity of the accretion disk. "Spiral arm" model for a fitting of the light curves of UX UMa is proposed. It reproduces well the observational data. The obtained azimuthal extent of the spiral arms is of similar to 90 degrees and their light contribution is about 17-30 of the total V flux of the disk. The obtained two dense structures at the outer disk covering partially the inner hot disk and the white dwarf at orbital phases similar to 0.7 and similar to 0.2 is in agreement with the predictions of the theoretical computations.
