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

Methods of optical emission spectroscopy (OES) are used to determine basic parameters of the plasma jet such as temperature, electron number density, and mole fractions of plasma components. The analysis is based on the measurement of a large variety of argon, oxygen and hydrogen spectral lines in the whole visible spectral region for various operating conditions. The electron number density is determined from a profile of Hb line. The temperature is obtained from Boltzmann diagrams and from the ratio of atomic and ionic lines. A discrepancy is found in evaluation of the excitation temperature from certain argon ionic lines. The mole fraction of oxygen significantly decreases towards the jet centerline. This effect increases with increasing temperature gradient, and is explained mainly as a result of inhomogeneous mixing of argon and water in the stabilizing channel of the torch.
