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

The dynamic behaviour of a double transferred arc is experimentally analysed. The arc chamber is equipped with four optical fibers aimed at the observation of arc space-time fluctuations. Terminal voltages and currents are also recorded. A particular low frequency behaviour of the arc is pointed out. It is characterized by erratic skips from rotating to quasi stable fastening on the primary nozzle-shaped anode. In either case the arc root looks rather evenly distributed than located in a definite position. The disappearing of the HF fluctuations when replacing the anode material by a better heat conductor material confirms the important stabilizating role played by the electrode cooling
