Many experiments on low cut filter were carry out to meet the requirement that balance of high frequency energy and low frequency energy is necessity for high resolution seismic exploration.
根据高分辨率地震勘探对高低频能量均衡的要求，对低截滤波进行了多次试验。
The attenuation factor of longitudinal wave was changing linearly, whereas the attenuation factor of the slow shear wave kept nearly constant with a low frequency on the exploration seismic band.
纵波的衰减系数在地震频带内基本上呈线性变化，而横波的衰减系数在地震频带内除低频外基本保持稳定。
Celestial gravitational wave source and the exploration to low frequency gravitational wave have also been discussed.
其中还介绍了天体引力波波源和现在低频引力波的探测现状。
