This shows that an earthquake may be predicted by making use of the variations of the frequencyattenuation coefficient if the available data are properly processed.
这表明，经过适当处理，是可以根据频率衰减系数的变化来预报地震的。

To facilitate realistic testing, the heart of real is the radio frequencyattenuation network, a system designed to simulate realistic field conditions for multiple radios.
为方便实际测试，REAL实验室的核心是射频衰减网络，可模拟多个无线电的真实部署。

Wavelet transform involves the two-variate function of frequency and time, which makes it convenient to simultaneously compensate for attenuation of seismic energy in frequency and time domains.
