differential approximation methodとは 意味・読み方・使い方

Denoting a linear differential operator of a nonlinear partial differential equation that a physical quantity U should satisfy as A, a nonlinear differential operator as B, and a nonhomogeneous term (source term) as (f), A.U+B(U)=f is solved by a successive approximation method.例文帳に追加

物理量Ｕが満たすべき非線形偏微分方程式の線形微分演算子をＡ，非線形微分演算子をＢ、非斉次項（ソース項）をｆとしたとき、Ａ・Ｕ＋Ｂ（Ｕ）＝ｆを逐次近似法を用いて解く。 - 特許庁
