For this reason, Daqing Putaohua Area has switched over to adopting the product of integral amplitude and travel time apparent difference and finally has won much better results.
为此，在大庆长垣葡萄花地区采用了积分振幅与地震波旅行时视时差的积来预测储层厚度，取得了较好的效果。

From this model section, a formula is obtained for calculating the amplitude of relative apparent annual variation of resistivity at a station characterized by two resistivity layers.
从此观点出发，导出以二层电性剖面为特征的台站正常地电阻率相对似年变化幅度公式。

The seismic reflection characteristics of volcanic rocks are mostly strong amplitude, apparent low frequency and the continuity is bad.
