line iteration 中文意思是什麼
line iteration
解釋
線迭代-
A discretization equation is derived by using a finite volume method in three - dimensional cylindrical polar coordinate system. algebraic equations are solved by iteration with a line - by - line method that is a combination of tdma in axial and radial directions, ctdma in tangential direction and adi method in three directions. the pressure and velocity coupling are solved with the simple algorithm
在三維圓柱坐標下，利用有限體積法推導離散方程；在軸向與徑向用三對角矩陣法（ tdma ） ，在周向採用循環三對角矩陣法（ ctdma ） ，採用交替方向亞鬆弛疊代法（ adi ）求解方程；推導同位網格下的壓力修正方程，用simple演算法處理速度與壓力的耦合；為加速收斂，採用適當的鬆弛因子。 -
Although the rfc of mts systems corporation is a general methods to process road simulation test all over the world, it contains two disadvantages as follows : 1. before the fatigue test, it will take a long period to carry through the off - line iteration to acquire a series control values
雖然美國mts系統公司的rpc方法是目前國際上進行道路模擬試驗普遍採用的方法，但它存在如下問題： 1系統進入正式的試驗之前，要用較長的時間進行離線迭代運算獲得控制量序列，逐步逼近給定的隨機波形。 -
For problems whose objective function or constraint functions have sharp curves on their contour maps ( such as the rosenbrock ' s function which has banana shape contours ), monotonicity may cause a series of very small steps, causing a huge number of iteration to reach their solutions. by using the nonmonotone technique, we get the sequence of successful interative point which should make the objective function mono - tonically decreasing. hence, we use both trust region strategy and line search technique and make each iterate generate an acceptable trial step in interior feasible set as next interative point
我們利用非單調技術得到使目標函數非單調下降的迭代點，因為非單調克服高度非線性化函數的求解問題，從而避免了只使用單調搜索在「峽谷」現象局部最優解被卡的情況，我們用信賴域策略和非單調線搜索技術相結合的方法，使演算法產生的迭代步落在可行域內點，同時又在信賴域內滿足接受準則。 -
Signatures for damage detection formed by modal parameters always need solve intricate mathematic iteration problem, which makes it difficult to realize real - time and on - line structural damage identification
鑒于用振動模態構造的損傷標識量往往需要求解復雜的數學反演問題使結構損傷識別的在線實時監測存在困難。 -
The first iteration defines the architecture - is it manual or automated, is it centralized or distributed, is it on - line or batch, is it flat files or a relational data base, etc
第一個迭代定義體系結構?它是人工的還是自動的，是集中的還是分散的，是在線的還是批命令式的，是直接文件存儲還是通過關系性數據庫等等。
