The super entropy produce criterion is a good tool to judge the system ' s abrupt change from a lower grade to a higher one. in this paper the entropy of the urban resource - environment system was defined, and in an example of its application the super entropy produce criterion of the urban resource - environment system reflected the real developmental process of the whole system. furthermore, in this paper, a new model for the grid size optimization of the finite element method ( applied to the water quality modeling of the topographically complicated river ) was brought forward based on the maximum information entropy theory in condition that the length of gird was given
超熵產生判據為我們提供了判斷系統從低級有序向高級有序突變過程的工具，本文提出了城市資源與環境系統熵的定義，在實例中的應用證明城市資源與環境系統的超熵產生判據較好地反映了整個系統的演化情況；另外，本文針對在城市復雜河道情況下，利用有限單元法求解河流水質模型時網格單元大小難確定的問題，引入網格信息熵的概念，提出了有限單元法求解河流水質模型的網格優化方法。 -

The surface panel method has been applied to predict the hydrodynamic performance of highly skewed propeller. the surface of propeller and its trailing vortex are discreted by a number of small hyperboloidal quadrilateral panels with constant source and doublet distribution. for highly skewed propeller, the conventional method generating grid oriented along constant radii will result in a high aspect ratio and a high skewness and a twist panel near the propeller tip on blade surface, which result easily in incorrect calculation results of velovity on blade surface, even in iteration divergence and calculation failure. a “ non - conventional grid ” is developed to acoid these problems. this grid can effectively solve the problem of the calculation and convergence for highly skewed propeller. the non - linear kutta condition of equal pressure on upper and lower at the trailing edge is executed by the iterative procedure. by sample calculating, the obtained results are satisfied the experimental data
採用面元法預報大側斜螺旋槳水動力性能，螺旋槳表面及尾渦面離散為四邊形雙曲面元，每個面元上布置等強度源匯和偶極子分佈.對于大側斜螺旋槳而言，槳葉表面採用常規的等半徑網格劃分方法在近葉梢處將導致大展弦比、大側斜和扭曲面元，這容易使槳葉表面速度的計算結果不正確，甚至會導致迭代過程發散及計算失敗.文中建立了一種「非常規網格」劃分方法，能有效地解決大側斜螺旋槳的計算和收斂問題.槳葉隨邊處通過迭代實現非線性等壓庫塔條件 -
Frame supported short pier shear wall structure with transition floors is a useful structure pattern with good ability in resisting seismic load. the lower part is frame with large opening column - grid while the upper part uses short pier shear wall with wide openings. so this structure decreases the difference between stiffnesses of lower part and upper part
帶梁式轉換層的短肢剪力墻結構，其下部結構為大開間的柱網框架，上部結構採用開洞較大的短肢剪力墻，有效地降低了轉換層上下結構之間的剛度差異，因而是一種抗震性能較好的結構型式。 -
