摘要：

The Standard Theory for hydrogen spectral lines asymmetry in dense plasmas is developed on the basis of rigorous and consistent approach with respect to simultaneous and complete account of the quadrupole interaction and the quadratic Stark effect. The complex multiparametric scaling and similarity dependence of the conventional asymmetry parameter for each separate Stark component and the H-beta line contour as a whole is revealed and studied in detail under the influence of: ionic microfield inhomogeneity and quadratic Stark effect in ionic microfield, electronic collision shifts and impact widths, "trivial" asymmetry sources, the Boltzmann factor and the dipole intensity scaling factor of frequency to the fourth power for the case of emission line. The comparison with the precision experiment on stabilized arc data for H-beta line, important for diagnostics, is performed and analyzed from the line center up to the far line wings.
