2) trend anomaly
趋势异常
1.

5a以上的趋势异常和年变规律的变化,震前1-2个月出现较丰富的短临前兆信息,如水位固体潮畸变、日潮差波幅增大、阶跃等微动态异常,这些分析结果曾在地震预报实践中发挥较好的作用。
2.
<Abstrct> Through ascertaining and tracing the apparent resistivity trend anomaly in Mianning Station,combining with the ocurrence of geomagnetic Z component lower point displacement and diurnal morphological short-impending anomaly, applying geoelectic and geomagnetic precursor anomaly to decide the mark of earthquake s "3 elements", Lijiang M7.

3) normal trend line
正常趋势线
4) the conventional tendency method
常规趋势法
1.

5) normal compaction trend
正常压实趋势线
1.

在四川盆地通南巴构造带,首先以井芯、录井资料和钻井泥浆比重资料为约束条件,利用泥岩段声波测井资料建立区域"正常压实趋势线";然后用精细速度处理获得的地震层速度剖面减去区域"正常压实趋势线"建立速度差值剖面,速度差值剖面上的异常低速带定性指示了地层超压范围;再采用速度 压力变换技术,建立压力系数剖面,定量分析地层超压,地层压力计算结果与实际钻井采用的泥浆比重较好吻合,说明利用地球物理资料、钻井资料及地质资料不但可以定性识别超压地层,而且可以定量预测地层压力;对不同压力封存箱的认识有助于分析地层含油气性延展方向,指导下一步勘探部署。
