Network traffic is broken down into different frequency, and anomaly change of network traffic is detected through the high-frequency power analysis, that is the change of wavelet variance.

将网络流量分解到不同的频段，根据高频段频谱能量，即小波方差的变化对网络流量异常进行检测。

It follows, that where the igneous basement is concealed by a sediment cover, the gravity anomaly may contain a high spatial frequency signal corresponding to the morphology of the buried basement.

意思就是说重力异常中频率比较高的信号可能与沉积层覆盖下的基底的起伏有关。
