【Abstract】 The influence of natural convection on thermoacoustic engine is studied in this paper. By a number of experiments, the author discovered that the change of spatial position greatly affected the oscillating temperature, the temperature gradient of regeneration in the travelling of thermoacoustic engine. By analysis, the author qualitatively explained these phenomena.更多还原
