finite difference schemeとは 意味・読み方・使い方

To provide an analytical construction method of a third-order calculation scheme for ensuring stability, relating to a finite difference numerical calculation method in a transport equation.例文帳に追加

輸送方程式における有限差分数値計算法に関し、安定性を保証する３次精度計算スキームの解析的構成法 - 特許庁

To estimate the state quantity, the mentioned four equations are differentiated by the Preissman four- point implicit finite-difference scheme, the differentiated equations are processed by Taylor expansion nearby an estimated value of the state quantity and linearlized, and unknown state quantities at points in the waterway are erased, thereby obtaining the linear characteristic equation of the waterway.例文帳に追加

状態量の推定においては、上記の４つの方程式をPreissmanの４点陰形式差分法によって差分し、差分化された式を状態量の推定値の近傍でTaylor展開して線形化し、かつ水路内点の未知の状態量を消去して水路の線形特性式を得る。 - 特許庁
