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

CCD camera with the imaging frequency 8000 fps was used for recording optical radiation of a thermal plasma jet. The fast Fourier transform of the recorded matrices representing the evolution of plasma jet radiation intensity was used to acquire frequency spectra for each pixel of the CCD chip. Spatial distributions of amplitudes at significant frequencies reflected by peaks in frequency spectra and corresponding to various types of oscillations were then evaluated. The results show that some types of oscillations are generated mainly on the jet boundaries or tail and their relative intensities may be sometimes distributed strongly asymmetrically, while the amplitudes corresponding to the plasma jet modulation introduced by the ripple of the arc current show distributions with several maxima at distinct plasma jet regions.
