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.

Book Chapter Description
In order to explore the relationship among the current, displacement, voltage of the linear compressor and the resonant frequency, a linear compressor was designed for the Joule-Thomson(J-T) throttling refrigerator. The linear compressor utilized the dual-coil to increase thrust. Firstly, the analytical solution of the displacement of the linear compressor under sinusoidal excitation was given by theoretical derivation. Then the changes of the current and displacement phase caused by different frequency excitations were revealed. It indicated that when the current caused the displacement to 90°, the linear compressor reached the resonance state. Besides, in order to verify the correctness of the inference, input same electric power at different frequencies, and test the phase angle of current and displacement. On the other hand, different pressure was charged into the system to test the performance of the compressor with nitrogen.
