Under the condition of " comparatively weak correlation between the two noises involved, coherence function is used as a frequency domain amplification factor for improving snr of the output signal to the filter and the speech enhancement effect. meanwhile, a real - time recursive algorithm is put forward in substitute for current algorithms based on short time fourier transform. the new algorithm will simplify computations and will be suited for real - time implementation together with the adaptive systems
接著針對上述nanc系統兩路輸入信號噪聲相關性弱的情況，用相干函數作頻域增益因子來提高輸出信噪比與改善語音增強效果，同時，通過一種實時迭代演算法解決了短時傅氏變換計算量大的問題，簡化了計算，便於實時處理與實際應用。 -
Structure is the factor that has to be considered in economic study. firstly, this paper discusses the importance of the factor of structure, subsequently applies the “ big push ” model of murphy, shleifer and vishny and spatial structural evolvement model to expound the evolvement mechanism of industry structure and spatial structure in the process of economic development based on combing references. it also builds a framework to explain the coherence between industry structure and spatial structure based on the common points between them
本文首先討論了結構因素的重要性，隨后則是在文獻梳理的基礎上分別使用墨菲（ kevinm . murphy ） 、施萊佛（ andreishleifer ）和維什尼（ robertw . vishny ） （ 1989 ）的「大推進」模型和克魯格曼（ paulkrugman ）的空間結構演進模型闡述產業結構與空間結構在經濟發展過程中的演進機理，並基於兩者的共通之處，構建了一個產業結構與空間結構一致性的理論解釋框架。 -
Chapter 4 : the paraxial propagation of partially coherent beams with the hermite - gaussian mode is investigated. the more generalized and simple expressions of the mean squared width and the beam quality factor of the beam with different mode order are obtained in terms of the cross - spectral density. our re - sults show that the higher order strengthens the variations of the mean beam width and the beam quality factor for partially coherent beams, and the relation between the two parameters of partially coherent beams is independent of the coherence length
第四章：初步探索了部分相干厄米高斯光的傍軸傳輸，根據交叉光譜密度得到了其不同模階數的平均光束束寬和光束質量因子更一般的解析表達式，較高的模階數使得光束展寬得越快，光束質量變差，且這兩個光束參量的關系與部分相干厄米高斯光的相干長度無關。
