Some characteristics of the measured wind pressure field were discussed, including distributions of wind pressure, the effects of shape ratio on total wind force coefficients, auto - and cross - power spectral density ( psd ) distributions of fluctuating wind pressure, characteristics of the proper orthogonal decomposition ( pod ) results of the measured wind pressure field, effects of reynolds number on wind pressure distributions, etc
根據測量結果對殼體表面風壓場特性進行了分析，包括風壓系數、整體風力系數、脈動風壓自功率譜及互功率譜、風壓場本徵正交分解特性、雷諾數對殼體表面風壓分佈的影響等。 -
I carried my research on both the two computation methods and fruitful results were obtained. for the fdtd method, i solved the instability problem of the method in the non - orthogonal coordinate system. for the pwe method, i introduce the linear transform in to calculate analytically the fourier coefficients of complicated photonic crystals
對于有限時域差分方法，我解決了一個影響這種方法在斜坐標使用的穩定性問題，得到了傳統的yee型差分在斜坐標里的擴充；對于平面波展開方法，我引入了線性變化求富里葉展開的系數，這種方法的好處可以很方便快捷的獲得復雜光子晶體的富里葉系數。 -
It is shown that, due to the real operations, the computation of the bi - orthogonal analysis window, the transforms coefficients, and the reconstruction of the original signal in rdgt case, can be significantly reduced as compared with the computation of those in the cdgt case. and the similarity between the rdgt and the discrete hartley transform ( dht ) allows the rdgt to utilize the fast dht algorithms for fast computation. meanwhile, the rdgt bears a simple relationship with the cdgt such that the cdgt coefficients can be directly computed from the rdgt coefficients
主要內容有：研究了一維和二維實值離散gabor變換（ rdgt ）方法，這種方法由於僅涉及實數運算，並可利用快速離散hartley變換演算法加速變換，因而在計算雙正交分析窗、變換系數以及信號重建方面都比復值離散gabor變換（ cdgt ）簡單易於實現，並且rdgt系數與cdgt系數的實部和虛部有著非常簡單的關系，因此前者的計算完全可以替代後者的計算，從而達到明顯減小gabor變換計算量的目的。
