【摘要】 针对建筑声学中共振效应现象,考虑了声音振动的非谐性所引起的振动能级之间的共振相互作用,利用定态微扰论,从理论上系统地分析了两态和三态之间的共振相互作用对能级能量、态函数和谱线强度的影响。在三阶非谐性近似下,得到了计及共振相互作用在内的能级能量、态函数和谱线强度的数学解析表达式。更多还原

【Abstract】 For the phenomenon of resonance effects in buildings acoustic,the resonance interaction at the vocalitical vibrant caused by the inharmonic vibration is discussed.Based on the perturbation theory,the influences of the resonance interaction between the two and three vibronic levels on the level energy,wavefunction,and the spectral line intensity are investigated in detail respectively.The analytical expressions of the vibronic level energy,wavefunction,and spectral line intensity with the consideration of the resonance interaction are also obtained under the third order inharmonic approximation.更多还原
