An inverse transformation section 5 references the H table and uses a numerical calculation so as to acquire an inner product of the numerical solution of the second integral equation and the Laplace transformation image multiplied by a softening element function in the weighted square integrable space. 逆変換部5は、Hテーブルを参照して、第二種積分方程式の数値解と軟化子函数を乗じたラプラス変換像との重み付き二乗可積分空間での内積を数値計算で求める。 - 特許庁
