field computations 中文意思是什麼
-
A new type of viscoelastic stochastic finite element method is established using first - order perturbation theory based on local averaging method of random field and karhunen - loeve expansion theory of random process. the amount of computations is greatly reduced by transforming correlated random variables to a set of uncorrelated random variables. the relations of different random response variables are analyzed and monte carlo simulations for viscoelastic stochastic structures are investigated
基於隨機場的局部平均法以及隨機過程的karhunen - loeve分解理論，通過一階隨機攝動方法建立了考慮材料近似不可壓縮的粘彈性隨機有限元公式，由相關結構分解減少計算量，分析了各結構隨機響應量之間的關系，給出了數字特徵的計算方法，研究了粘彈性隨機結構的montecarlo模擬驗證方法。 -
A least squares solution via singular value decomposition is used to solve the matrix equation. computations with synthetic data, where the near field of several typical antenna configurations are got over various geometric surface, illustrate the accuracy of the method
為了證明本方法的計算準確性，我們給出了幾個不同輻射源在不同近場測量幾何面下的近場和遠場計算結果，與解析公式的計算結果相比較，一致性很好。 -
Comparison between the computations and field tests shows that the software can provide reliable predictions for natural ventilation cases and that the values for empirical constants including train friction coefficient used by the model are in the proper range
通過數值計算結果與現場試驗結果的對比，說明該程序對隧道自然通風的計算結果是正確可靠的，同時，也說明了數值計算所採用的物理及數學模型和列車摩阻系數都是合適的。
