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

摘要

A simple spectroscopic method has been developed for characterizing atmospheric high temperature plasma jets in gas mixtures containing hydrogen. It is based on the measurement of one spatially resolved spectrum comprising hydrogen Hβ line and ionic lines of other plasma species, and the assumption of local thermodynamic equilibrium. A few characteristic spectral quantities from the measured spectra are used to determine both the temperature and the composition simultaneously. The applicability of the method is illustrated for the case of H2O-Ar DC arcjet in a wide range of plasma temperature and mole fractions of plasma species. It is shown that at least in the jet core the assumption of partial LTE appears to be valid. The method is suitable for ready monitoring of industrial plasmas.
