The infrasonic vibration generator is established on the principle or beat frequency. Starting from this principle, we study the frequencies of two pairs of special forks and find that there exists an infrasonic frequency function between the forks.
次声振荡发生器建立于拍频原理的基础上，按此原理我们研究两对特制音叉的频率，并找出了在这两对音叉间所存在的次声频率函数。
Vehicle interior infrasound is primarily caused by the infrasonic frequency vibrations of vehicle body panels excited by road roughness and aerodynamic infrasound due to air turbulence and perturbance.
车内次声主要是由道路不平度随机激励引起车身板件的次声频振动及车外空气的紊流扰动所产生的空气动力学次声形成的；
Cell protein increasing curve was found to be concomitant with amino-N consumption curve in responding to the rise of infrasonic frequency ( fig. 3).
随着频率的提高，细胞蛋白增加曲线与氨基氮耗增加曲线相伴着上升。
The infrasonic radiation equipment, which can adjust the frequency and amplitude of infrasound, is developed.
并在此基础上，研制出一种频率、幅度均可调的次声发生装置。
