common midpoint 中文意思是什麼
common midpoint
解釋
共中心點-
For processing of 3d and 3c seismic data, the reflected p - waves can be processed with the conventional methods, while the reflected converted waves can not be processed with the conventional p - wave processing methods, because their travel paths are asymmetrical, their common midpoint gathers are no longer common reflection point gathers, and their time - distance equation is non hyperbolic
在三維三分量地震勘探資料處理中，對于反射縱波資料可以採用常規方法進行處理；而對于反射轉換波資料，由於其傳播路徑的非對稱性，轉換波共中心道集不再是共反射點道集，轉換波時距方程也不是雙曲方程，因此不能採用常規縱波處理方法來處理轉換波資料。 -
The proposed function has same properties just as the ones of paper [ 1 ], unifies the forms when the intervals have common endpoint or not, avoids the impact of the level and dimension of values and make the extension analysis be more objective, is continuous for all real field but the common one, gets the maximum value at the midpoint, and has more applicability
該初等關聯函數具有與文[ 1 ]初等關聯函數相似的性質，且統一了有公共端點和無公共端點區間類型，能消除量級和量綱的影響，使得可拓優度評價結果更客觀，在除了公共端點外的全體實數域內連續且在中點取得最大值，並有更寬的適用范圍。
