中文摘要：

考虑输入和反映的波浪，在在结束和一个系统的输入的声学的阻抗之间的关系理论上被分析。关门并且影响压力，容量的速度，阻抗和声学的工作的开的声学的配置详细被比较。基于上述调查，一露天旅行波浪 thermoacoustic 生成器被设计并且制作。它由一个循环试管，在一结束开的一个共鸣器，一个改革者，和热、冷的热 exchangers 组成。它是小规模和简单配置。反响的频率是在在空中的 1 个酒吧的 74 Hz。当加热力量分别地是 210 W 时，在开的结束和离开开的结束远的 0.5 m 的最大的声学的压力从 20 Pa 的参考价值是 133.4 dB 和 101 dB。声学的压力作为低频率的声学的来源为实际申请是合理的。在进一步的工作，我们相信在开的结束的声学的压力能完成 150 dB，它能是在存在声学的发电机的问题的一个答案。这些问题包括低声学的压力和系统复杂性。它能为为工业来源必要的高声学的压力为低频率和远程的噪音实验被用作基本声学的来源，并且作为供应。

英文摘要：

Taking the input and reflected waves into account,the relationship between the acoustic impedance at the end and the input of a system were theoretically analyzed.Closed and open acoustic configurations that influence the pressure,volumetric velocity,impedance and acoustic work were compared in detail.Based on the above investigation,an open-air traveling-wave thermoacoustic generator was designed and fabricated.It is composed of a looped tube,a resonator open at one end,a regenerator,and hot and cold heat exchangers.It is a small scale and simple configuration.The resonant frequency is 74 Hz at 1 bar in air.The maximum acoustic pressures at the open end and 0.5 m far away from the open end are 133.4 dB and 101 dB from a reference value of 20μPa when the heating power was 210 W,respectively.Acoustic pressure is reasonable for practical application as a low-frequency acoustic source.In further work,we believe that the acoustic pressure at the open end can achieve 150 dB,which could be a solution to problems in existing acoustic generators.These problems include low acoustic pressure and system complexity.It can be used as a basic acoustic source for low frequency and long-range noise experiments,and as a supply for high acoustic pressures necessary for industrial sources.
