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.

Artifact Description
The gas holdup in a new self-inspirating gas-liquid stirred tank with dual impellers was studied. The effects of blades angle of gas dispersion channel, stirring speed, medium viscosity and impeller combinations on gas holdup were analyzed. The results showed that when the blades angle of gas dispersion channel was 30°, more gas could be induced at the same speed or inputting power. The gas holdup increases with the increaseed of stirring speed and medium viscosity. The suitable impeller combination was 6SBDT+6PBUT. This combination had a higher rate of gas induction and ability of gas dispersion, and had a higher gas holdup. The relationship between gas holdup and unit volume power consumption was ε∝（Pg/V）2.4, as the unit volume power consumption increasesed, the gas holdup increasesed signific-antly, the effect of gas-liquid dispersion was better, and the mass transfer efficiency was higher.
