     长颈管在微型脉冲管制冷机中的应用分析
短句来源
     The experimental results show that the benefit of using only inertance tube is unapparent in miniature PTC. The lowest temperature achieved by the PTC with inertance tube is only 107.3 K at operating frequency of 50 Hz, which is higher than the lowest temperature obtained by the double-inlet PTC.
     对于本实验中的微型脉冲管制冷机,以长颈管作为调相器时最低制冷温度为107.3 K,低于以单纯的小孔阀作为调相器时所获得的最低制冷温度,但还达不到双向进气的水平。

  inertance tube
For this pulse tube and regenerator, we have found the optimized inertance tube length for a calculated diameter and for a double inertance tube.
      
Run two was done with a double inertance tube; both lengths were optimized.
      
Then comes either the inertance tube or the reservoir volume.
      
The best performance was achieved with an inertance 4,5 in place but the system was also run without the inertance tube.
      
The best performing single diameter inertance tube had an inner diameter of 2.57 mm and a length of 2.20 m.

Pulse tube refrigerator has undergone great development in recent years. To find better and more reliable and simple phase shift mechanism at the hot end of pulse tube refrigerator, several devices have been proposed, two of which are symmetric nozzle and long neck tube. In this article, experiments have been done to compare performance of these two devices with pin valve.
