We make a subtly geological model profile in Sanzhao sag in Songliao basin, then we can make a series of models with varies S/N ratios and with varies dominant frequency accordingly.
对松辽盆地三肇凹陷制作了精细地质模型剖面，及相应制作了不同信噪比、不同主频的正演地震模拟剖面。
The signal's amplitude spectrum reveals that there are two main frequency, the higher is the probe signal's dominant frequency and the lower is the testing plane's free vibration frequency.
频谱分析表明测试信号中含有两个主频，分别对应发射探头的发射主频与测试面自振频率（采用ANSYS有限元程序作半空间体模态分析加以验证）；
The main parameters that effect horizontal resolution of migration imaging were identified as medium velocity, dominant frequency of seismic wavelet and aperture Angle of migration processing.
结果表明，影响偏移成像水平分辨率的主要参数是介质速度、地震子波主频和偏移处理的孔径角。
We also use this system to study the relationship of gastric sound and EGG. The result showed that the dominant frequency decreased and the dominant power increased when the gastric sound appeared.
我们也使用床边记录系统，探讨胃音和胃电的关系，从研究结果可以得知，在胃音发生时，胃电的主频率将明显降低而主频率之功率则会有明显的增加。
