local anomaly

基本解释

There is no false local anomaly.
不出現假侷部異常；
So the local anomaly of geophysical field and remote sensing structure are of important signs for ore prospecting evaluation.
這些遙感搆造和地球物理場中的侷部異常，是進一步找鑛評價的重要標志。
Using the short-period conversion function and extracting local anomaly from the geomagnetic field, we have re-studied the variation of the geomagnetic field before and after the Heze 5.9 earthquake.
本文使用地磁短周期轉換函數和提取地磁侷部異常的方法，對菏澤5.9級地震前後地磁場的變化進行了再研究。
