相鄰斑 的英文怎麼說
中文拼音 [xiānglīnbān]
相鄰斑
英文
adjacent spot-
All patches adjacent to water are excotone and they have twist edges and narrow figure, which is suitable with the function of the frequency of exchanging the matter and energy, what ' s more, these patches are mixture in the plant community styles, which is according with the importance character of the excotone which is that many system coexist. 3 ) : the dissimilarity of plant community is key factor in composing the landscape heterogeneity
鄰水斑塊邊界曲折，形狀狹長，多為混合型斑塊，這與生態交錯帶多系統共存特性是相適應的。樹種結構組成差異是構成花港觀魚公園綠地景觀異質性的主要因素，不同木本植物群落類型在花港觀魚公園不同綠地斑塊類型中交錯分佈，同一斑塊類型內部群落相異性指數較高。Just like that the core patch which is not adjacent to water and hilly woods has the flat edge, near round shape, high trees diversity and abundant native trees, which can reduce the external disturb and protect the native trees. in addition, the matrix in the landscape is the patch that is flat, not adjacent to water and scatter woods has low fragmentation degree, smooth edge and near ellipse shape, which is adapted to matrix
如，非鄰水山地密林團聚分佈，邊界平滑，呈圓形，樹種多樣性指數高，當地物種豐富，這種格局能顯著降低外部干擾，保護主要當地物種，與核心斑塊的功能相適應；非鄰水平地疏林斑塊邊界平滑，近橢圓形，這種格局有利於分散干擾危險，與本底斑塊的功能相適應。Under a unified frame, different despeckling sub - algorithms are designed to despeckle different kinds of regions : a modified acmap algorithm ( simulated annealing correlated neighborhood map despeckling algorithm ) is used to depress the speckle in homogeneous regions, and the macro structural information is introduced into the despeckling algorithm in heterogeneous regions to protect the structures
在統一的框架下，針對不同的描述模型的特點設計了相應的相干斑抑制方法。針對平穩區域設計了改進的acmap演算法（基於模擬退火和相關鄰域的最大后驗估計相干斑抑制演算法） ，針對非平穩區域將分割得到的宏觀結構信息引入到演算法中，有效的保護了宏觀結構性信息。The fourth - order explicit upwind - biased compact difference schemes are used in the spatial discretization of the nonlinear convection terms. these difference schemes can be used in all computational region including the boundary neighborhood, and can overcome the difficulty not adapting simultaneously in the boundary neighborhood for general three - dimensional fourth - order central difference schemes, and improve computational stability a nd resolution. the compact difference equations with high accuracy and resolution for solving the incompressible n - s equations and perturbation equations are composed of these compact difference schemes, and provides an effective numerical method for the investigations of the turbulent spots and coherent structures
文中發展了四階時間分裂法用於navier - stokes方程及其擾動方程的時間離散；對分裂得出的關于壓力的poisson方程和關于速度的helmholtz方程，建立三維耦合四階緊致迎風差分格式；這些格式適用於包括鄰近邊界點在內的計算區域，克服了三維各自用四階中心差分格式離散不適用於邊界鄰域的困難，並提高了穩定性和解析度，用這些格式分別組成了數值求解navier - stokes方程及其擾動方程的高精度、高解析度的緊致差分方程組，為湍斑及湍流相干結構的研究提供了有效的數值方法。分享友人
