Due to the complexity of geological structure and metallogenic conditions in metallic ore districts, only when seismic wave fields are studied from known areas to unknown areas and the seismic time profiles are interpreted by combining physical modeling results with other geophysical anomalies can the study of seismic method for metallic ore exploration yield valuable results
由於金屬礦區地質構造和成礦條件比較復雜，金屬礦勘查中的地震方法技術研究只有採用從已知區的地震波場研究未知區的地震波場，並結合物理模型實驗結果和其他物探異常對獲得的地震時間剖面進行解釋，才能取得有價值的成果。 -
In many fields, such as remote sensing, nuclear medical, computer tomography, geophysical prospecting, groundwater hydrology, global ocean modeling, image processing, tumor detection, nondestructive detection, the objective of applied sciences and engineering is the recovery of the original signal given a collection of noisy observations of the original signal ; we call these problems inverse problem
在遙感技術、核醫療技術、計算機斷層掃描（ ct ）技術、地質勘探、地下水文學、電磁輻射、圖像恢復和重構、腫瘤檢測、非破壞性檢測等科學研究和工程實踐中，經常需要根據一組觀測到的數據來估計目標的真實信號，而觀測到的數據往往是真實信號經模糊、失真和加噪等過程后所得的輸出信號，通常稱這類問題為逆問題。 -
