摘　　要：基于线性热声理论,通过计算证明了在层流状态下,带气库的惯性管调相机构可以用不带气库的单纯惯性管结构取代,单纯的惯性管结构更加便于在实验中进行调节变化,并且在尺寸的选择上具有更大的灵活性。在一台脉冲管制冷机上分别采用单纯惯性管和带气库的惯性管作为调相机构获得了相同的温度。Based on linear thermoacoustic theory, it was proved that phase shifter composed of an inertance tube and a reservoir can be taken place by a single inertance tube without reservoir. It was found that the latter is more flexible in dimension and more convenient in experiments. In the same pulse tube refrigerator, the same cooling temperature was obtained by using these two phase shifter.
