The oscillation frequency only was the function of oscillatingtube length, not influenced by the spliter.
振荡频率几乎不受分流劈距的影响，它只是振荡管长的函数。

In thermoacoustic system, the oscillating heat transfer in regenerator is along the axis direction of the stack and in heat exchanger it is along the radial direction of the tube.
在热声发动机系统中，回热器的振荡换热是沿流体通道的轴向，而加热器振荡换热主要是沿流体通道径向。

A numerical model for simulating the oscillating flow characteristics in a high frequency miniature pulse tube refrigerator was developed.
