Metric Options: CountsSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
In order for SO 3 measurement without impurity gas interference in coal-fired power plants, a quantitative measurement model for sulfate in the temperature range of 298.15–343.15 K based on vacuum ultraviolet absorption spectroscopy was created. A vacuum ultraviolet absorption spectrum measurement system that eliminates oxygen interference was set up, and the vacuum ultraviolet absorption of sulfate was ascertained at 1 atm pressure by means of vacuum combined with nitrogen purging. The law of the vacuum ultraviolet absorption of sulfate with temperature was revealed, that the full width at half maximum ( FWHM ) and peak absorbance ( A max ) both increased linearly with temperature. The quadratic function relationship between the integrated area ( OP ) of the vacuum ultraviolet absorption spectrum of sulfate and temperature was found, and a universal sulfate concentration measurement model was established in the temperature range of 298.15–343.15 K. The average relative calculation error of this model for 0.0025 mol L −1 sulfate was as low as 0.6%, which supports the measurement of trace sulfate.
