The Impact Factor measures the average number of citations received in a particular year by papers published in the journal during the two preceding years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) IF: 0.4 The Immediacy Index is the average number of times an article is cited in the year it is published. The journal Immediacy Index indicates how quickly articles in a journal are cited. Immediacy Index: 0.1 The Eigenfactor score, developed by Jevin West and Carl Bergstrom at the University of Washington, is a rating of the total importance of a scientific journal. Journals are rated according to the number of incoming citations, with citations from highly ranked journals weighted to make a larger contribution to the eigenfactor than those from poorly ranked journals. Eigenfactor: 0.00005 The Journal Citation Indicator (JCI) is a single measurement of the field-normalized citation impact of journals in the Web of Science Core Collection across disciplines. The key words here are that the metric is normalized and cross-disciplinary. JCI: 0.07 SJR: 0.198 SNIP: 0.48 CiteScore™:: 1.1 H-Index: 20

RÉSUMÉ

The paper is devoted to diagnostics by optical emission spectroscopy of inhomogeneous plasmas, which cannot be considered as optically thin. The consideration is limited with steady plasmas close to local thermal equilibrium. The distribution of plasma temperature along the observation direction has one maximum and a monotone fall around it. Numerical modelling has been performed to find the relations between the plasma opacity and spatial distribution of thermodynamic parameters, from one side, as well as intensity and spectral profiles of atomic lines in the plasma volume emission, from another side. Argon plasma at atmospheric pressure and its atomic emission spectra have been chosen for the modelling. Stark broadening has been supposed to determine local line profiles. The relations obtained allow evaluating absorption and inhomogeneity rates of the plasmas by spectral line profiles in the volume emission. Also, the plasma temperature can be determined using relative intensity of spectral lines in the plasma volume emission recorded directly and after its reflection by an auxiliary mirror behind the volume. The modelling results show the technique feasibility, its application range and error limits.
