摘要

This part of a series of papers examines the more general problem in which it is assumed that the fluctuations in the intensity of radiation emerging from a medium are caused by random variations in both the optical thickness of the structural elements and the power of the energy sources contained in them. The frequency dependence of the relative mean square deviation (RelMSD) is investigated for different possible relationships among the parameters of the fine structure components. It is shown that the level of fluctuations at the central frequencies of a line can be greater than or smaller than in the far wings. The dependence of the RelMSD on the number of components and the number of possible realizations of their optical properties is discussed. The influence of random variations in the scattering coefficient on the observed integral intensity of a spectrum line is also examined. Observations of several relatively strong EUV lines from the SOHO/ SUMER space program are presented for comparison. These data indicate that there is a correlation between the frequency dependence of the RelMSD and the characteristic temperature for formation of these lines.
