The calculation method of ln ( / tan # ) index widely used is the multiple flow direction algorithm developed by quinn et al. it can been seen that, in the algorithm, the contour length normal to the direction of flow flowing out the current cell is used to determine both a and tan #, and that the calculated total cumulative contributing area of downslide grid cell does not include the area of the current cell
目前普遍使用的計算該地形指數的方法為多流向法。方法中計算和tan用的均是與流出單元網格流向垂直的等高線長。另外計算下坡單元網格累積匯流面積時沒有考慮欲計算ln （ tan ）值的單元網格的面積，這些是不合理的。 -
Thirdly, there is a preferential path for dispersion flow near the percolation threshold ; fourth, the longitudinal dispersivity is scaled with grid length
由於在逾滲閾值附近，網格可視為近似分形結構，對二維網格，縱向彌散系數和尺度之間存有指數增加關系 -
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。 -
Wirings of the poly layer are always utilized under the silicon grid technics. to control the macro - cell signal delay and improve signal integrality, the crossing among different nets must be averagely distributed to reduce the number of layer permutation. the metal layer wirings should be maximized and the length of poly layer wiring in each net should be minimized
硅柵工藝晶體管級布線利用多晶層走線，為了控制宏單元時延性能及改善信號完整性形態，關鍵是不同線網間交叉的均衡分配以減少走線的換層次數，最大化金屬層走線以及每一線網多晶層走線長度的有效控制。 -
The conductor-length problem was solved by forming the required length of wire into a grid pattern.
電阻絲長度問題，是採取將所需長度的金屬絲做成柵狀結構的辦法解決的。 -
In order to research the aerodynamic characteristics of grid fins effected by width to length ratio, the grid fins of three hight to width ratios were adapted in wind tunnel experiments at subsonic, transonic and supersonic speeds
為研究它對柵格翼氣動特性的影響規律，本研究採用風洞實驗的方法對3種不同格寬翼弦比的柵格翼在亞、跨、超聲速3個馬赫數下進行了氣動特性的研究。 -
Numerical modeling of flows by solution of reynolds averaged navier - stokes equations with baldwin - lomax algebraic turbulence model is presented as well. a turbulence reference grid is used to supply the necessary length scale for each cell
紊流模型是採用baldwin - lomax代數模型，為了能把b - l紊流模型應用於混合網格中，引進了能提供紊流模型所需要的參數的參考網格。 -
By the method used in 13, 32, one can estimate the mean depth d and the effective length l in each grid. the slope of the aquifer can also be calculated through an analysis of the digital elevation model. the two parameters a and b in the quasi - steady subsurface model can be calculated by the following method : the nonlinearity parameter b is taken to be 2. 0, the parameter a can be calculated by plotting the values for dq dt versus q in a log - log graph 13
