One is the non - orthogonal gabor - daubechies frame, or g - d frame, a complete set of discrete window fourier functions which are constructed by space - shifting and harmonically modulating a gaussian window. although a g - d frame is not an orthogonal basis, it bears considerable advantages for the study of physical problems, especially those related to the wave field extrapolation, due to the optimal localization properties of the gaussian window function under the heisenberg uncertainty principle
其一為將高斯窗函數經平移和調制而構成的一組窗口富里葉框架（ gabor - daubechies框架，或g - d框架）基本函數，另一種為在富里葉分析和小波包理論基礎上發展起來的局部餘弦基函數。 -
Based on the firsthand observation information obtained from air observation, this paper gived a second extrapolation to aircraft possible flight path and made checks on targets relativity by the method of utility function overall evaluation, accomplished the data fusion of targets information, and resolved the problem of relating of air observation information fusion and flight path extrapolation
摘要在得到對空觀察哨直接觀測信息的基礎上，對目標可能航向進行二次外推，並利用效用函數綜合評估法對目標相關性進行檢驗，完成對目標信息的融合，解決了觀察哨情報數據關聯和航跡外推問題。 -
After a short - term load forecasting method based analogous and linear extrapolation is proposed, the load forecast and the priority of equipment action are led into static reactive power optimization. the aim function is constructed for the practical situation of power system. on the basis of traditional genetic algorithm the fitness function and the holding of population diversity are improved
在提出基於相似日和線性外推的短期負荷預測新方法的基礎上，將負荷預測和設備動作優先級引入靜態無功優化中，並結合電網實際情況，構造了實用的目標函數，對遺傳演算法的適應度函數和群體多樣性的保持進行了改進，採用鄰域搜索運算元增加遺傳演算法的局部尋優能力。 -
A hybrid migration method, named " fourier finite - difference migration ", is a post - stack depth migration scheme. the downward extrapolation operator is split into three operators : one operator is a phase - shift operator for a chosen constant background velocity, another operator is the well - known first - order correction term, and the third operator is a finite - difference operator for the varying of the velocity function. phase - shift downward extrapolation and finite - difference downward extrapolation preserves the advantage of phase - shift method and finite - difference method
傅立葉有限差分（簡稱ffd ）偏移演算法是一種疊后深度偏移演算法，其向下延拓運算元是一種混合運算元，包括三項：一項是處理常速的相移運算元，一項是一階相移修正運算元，最後一項是類似45度方程的有限差分運算元，用來處理劇烈橫向變速。
