摘要: 用声功率法测量了耦合共振管在不同耦合强度下的频率特性,发现随着耦合强度的增大,耦合共振管的频率的回避交叉现象越明显,这与量子力学中能级的回避交叉具有数学上的相似性.
关键词: 耦合共振管, 声功率, 共振回避交叉
Abstract: In this paper, we apply acoustical power method to measure the frequency characteristics of the couple acoustic resonant tube under different coupling strengths. Our experiments show that the phenomenon of avoided crossing in coupled acoustic resonant tube is more obvious as the coupling strength increases. The mathematical similarity between acoustic systems and quantum mechanical is also shown.
Key words: coupled acoustic resonant tube, acoustical power, avoided crossing
