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.

Conference Paper Description
The method of experimental determination of the surface catalytic recombination coefficient of ultra high temperature ceramics(ZrB+SiC) in dissociated subsonic air flows generated by a 1MW high frequency plasma wind tunnel of CARDC are discussed. The complex diagnostics of nonequilibrium plasma flow was also developed for calculating air flow field parameter in working chamber of HF-plasmatron. The UHTC samples tested was produced by hot pressing, and then machined into samples for catalytic measurement. The sample for the test is disk shape with 20mm diameter and 5mm thickness. One types of materials were tested under a subsonic condition with enthalpy of 16.5~25.6MJ/kg and ambient pressure of 5.4, 12.4, 22.4kPa.The recombination coefficient of ultra high temperature ceramics (UHTC) in the surface temperature range 1406~1622K were measured. It shows that the catalytic recombination coefficient of ultra high temperature ceramics under high surface temperature condition depends not only on the surface temperature but also on the partial pressure.
