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

RESUMO

A quick spectroscopic diagnostic system (see Figure 1) for the flame temperature is set up in this paper. It consists of optic imaging system, scanning system, dispersive system, photoelectricity conversion cell, operational amplifier, a computer-based data collection system, and data processing. The temperature profile varying with the time can be quickly measured with this system. The intensity of up to four spectral lines can be simultaneously measured.
The satisfied results have been obtained in measuring the temperature of two kinds of flame (the transparent optics-thin flame and the flame with enough solid particles) by the system.
1. The flame of coal powder: By analyzing the radiation characteristics of the flame of coal powder, a four- wavelength model is proposed in this paper to measure the flame temperature of coal powder. The model is that four equations are set up in four chosen wavelengths and the flame temperature can be obtained by solving the equation group. With the measurement system based on the model, in which the radiation of the combustion chamber surface and the scattering of the solid particles are consistently accounted for, the temperature of the flame can be quickly and accurately measured without a reference radiation source.
2. Thermal plasma: The temperature profiles varying with time for the nonsteady arc and flashover arc near the surface of a polluted plate are derived by employing the relative intensity method and the absolute intensity method.
3. Solid propellents: The spectrum for the flame of the solid propellants is measured. A lot of spectral lines are found in the spectrum of the flame, which are important information for temperature diagnosis.
