Based on mechanic equivalent circuit of the longitudinal ultrasonic horn, the resonance frequency and the amplitude magnification coefficient of three kinds of loaded horns are studied.
在纵振型变幅桿等效电路的基础上,研究了三类负载超声变幅桿的共振频率与放大系数。
The seismic response indicates that the harder the soil is, the larger the magnification coefficient of the acceleration response is.
