Abstract

The correlation between morphological types and spectral-morphological (SM) properties of galaxies with UV-excess was found. The distribution of mean geometrical angular diameters of galaxies by the morphological types was determined. It is shown if mean geometrical diameters of galaxies are increased then relatively quantity of spectral morphology $d$ is increased. By the same rate of UV-excess radiation intensity the grouping morphological classes of galaxies are as follows: $St+C, E+Sph, S+L$ and $Ir$. It is found that $m_{pg}/\Box^{\prime\prime}$ and $m_J/\Box^{\prime\prime}$ with high UV-excess is more than the same value for galaxies with low UV-excess, except $m_{pg}/\Box^{\prime\prime}$ in group $E+Sph$. It is also shown, that $m_{pg}/\Box^{\prime\prime}$ and $m_J/\Box^{\prime\prime}$ of galaxies with a spectra morphology of type $s+sd+ds$ is more than that for type $d$.
