Huang, Su-Shu Abstract In this paper it is shown that Wright's observed relation between turbulent velocities and ezcitation potentials can be understood if it is assumed that the mean turbulent velocity in stellar atmospheres decreases exponentially with optical depth in the atmosphere. Theoretical curves between turbulent velocities and excitation potentials derived on this assumption agree well with the observations. Wright's further result that the turbulent velocity is greater for ionized atoms than for the neutral atoms can also be interpreted, as also the variation of turbulent velocity requlred by Allen's analysis of the spectral lines at different points of the solar disk.
