查询词典 resonance method

Results The amplitude of rabbit stomach in front-back direction rapidly increases after 5 Hz and reaches the peak of 277.5% input at about 8Hz and then deceases gradually. The resonance frequency is 7-9Hz. and the amplitude of vibration is higher than 150% of input amplitude from 6Hz to 10Hz. The resonance frequency reduces and the maximum amplitude increases with the increase of stomach mass and volume.

结果 在2~50Hz频率范围内家兔胃在前后方向的振动在5Hz后振幅迅速增大，在8Hz左右达峰值，达到施加振幅的277.5%，之后又逐渐减小；共振频率为7~9Hz，在6~10Hz频率范围内胃的振幅都超过了施加振幅的150%；随着胃的质量、体积的增大，胃共振频率变低，但最大振幅增大。

The results are verified from deep to extremely shallow water conditions. The shoaling waves, standing waves, 3D disturbance waves, tidal waves and solitude waves are simulated and verified,and waves over an underwater bar,the diffraction near single breakwater, breakwater gap, offshore breakwater, Breakhoff experiment are taken into account in this model. Furthermore, the wave harbor resonance under special topography, and "Bragg" resonance are simulated. The wave refraction problem under current fields,the nonlinear wave refraction-diffraction under "Arthur" current field, and the wave propagation under slowly varying current field are studied. The favorable calibrations show the model's feasibility in dealing with the wave nonlinearity and simulation in both deep and shallow water.
