| 摘 要： | 采用网络模型计算热声热机系统的输出声功率。对不同回热器填料以及对同种回热器在不同间距和不同振荡压力比条件下进行了数值计算，计算结果表明：在其它相同条件下，针束型回热器热机系统输出声功率比板叠回热器热机高。

| Abstract: | The network model is used to calculate acoustic power of thermoacoustic prime mover Numerical calculations are made under different conditions including different stack matrix,different oscillating pressure ratios(PR) and plate spacing of the same matrix The calculated results show that the acoustic power of pin array stack is superior to that of parallel plate stack under other same conditions |

| Keywords: | thermoacoustic engine network model acoustic power pin array stack |
