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: 0.7 To calculate the five year Impact Factor, citations are counted in 2017 to the previous five years and divided by the source items published in the previous five years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) 5-Year IF: 0.7 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: 0.00016 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: 0.18 SJR: 0.313 SNIP: 0.6 CiteScore™:: 1.6 H-Index: 16

RÉSUMÉ

An experimental study of the ignition and combustion of uncoated and 0.75% Mg-coated boron particles was performed in the post-flame region of a flat-flame burner at atmospheric pressure. In the post-flame region, gas temperatures ranged from 1772 to 1993 K, and mole fractions of oxygen ranged from 12.6% to 27.7%. The uncoated and Mg-coated particles all have nominal diameters of 2−3 μm, and the average thickness of the Mg coating is 6 nm. Single particle combustion times and particle velocity during ignition and combustion were measured. Using a specially designed optical and electronic control system, particle burning phenomena and trajectory were clearly observed. Results indicated that the lengths of ignition delay zone (Di) and first-stage combustion times (t1) of the Mg-coated boron particles were slightly shorter than those of uncoated boron particles. The second-stage combustion times (t2) and total burning time (tb) were found to be decreased with increasing flame temperature or oxygen mole fraction for both uncoated and 0.75% Mg-coated boron particles.
