The vibrational modes and spectrum are very different if the free boundary condition is adopted, and the spectrum is divided into low, medium and high frequency branches. 若采用自由边界条件，则模花样和振动频谱完全不同，这时只能分为低频支、中频支和高频支。 - 2
Based on the random variation of cavity length, characteristics of the medium index and mode competition effect, low-frequency beat and noise continuums are explained. 根据腔长的随机变化、介质色散特性和模竞争效应解释了低频拍和连续噪声谱。 - 3
ConclusionThe modulated medium frequency low frequency current hydroelectric bath therapy is a simple, safe and better effect method for sequela of ankle fracture. 结论低频调制的中频电水浴疗法是治疗踝部骨折后遗症的一种简单、安全、疗效好的方法。
