helium tube 中文意思是什麼
helium tube
解釋
氦管-
Recent experiments have succeeded in obtaining oscillations from the new system, with frequencies of 66hz and 23hz for the cases with helium and nitrogen as the working fluids, respectively. the traveling wave system is expected to be one of the good candidates as a driver for pulse tube refrigerator, leading to a thermoacoustically driven pulse tube refrigerator without any moving component
