Because of periodically faulting hydrocarbon pumping migration along fault zone is periodic, intermittent and pulsant, and hydrocarbon migration and accumulation often locates the newest strata.

断裂周期性破裂活动的特征决定了油气沿断裂的垂向泵吸运移呈周期性、间歇性和脉动的特点，同时也决定了油气易于在断裂错开的最新层位聚集成藏。

On the basis of relation between the seism and solar activity, it is pointed out that the periodicity evolution of the seisimic activity is under the modulation of solar activity.

在太阳活动与地震相关研究的基础上指出：在周期性太阳活动的调控下，地震活动也显示出明显的周期性演化。

The ANNs models of the periodic defected ground structures and a novel combinatorial nonperiodic defected ground structures with the characteristic of double stop band have been developed in this paper. The structure sizes of DGS and the frequencies are defined as the input samples of ANNs, the parameters of transmission coefficient calculated by FDTD method are sampled and defined as the output samples. For the PDGS with biggish structure sizes the transmission coefficients have the tiny dither owing to abnormal disturbance and the training samples have been smoothed by the least square method and five-spot triple smoothing method.
