摘要
槽波测量用速度检波器常产生高频谐振，是由于横向激励引起的二次谐振所致。采用加速度检波器芯体、增大速度检波器芯体阻尼等措施，可改善二次谐振的危害，经实际应用效果较好。
The high frequency resonance is generated usually by velocity detector used inseam survey.It is resulted from the secondary resonance due to the transverse excitation.The harm of the secondary resonance could be improved by the measures such as using the acceleration detector core body,increasing the damp of velocity detector core body and so on.The practical application provides a better result
