a concept in elementarygeometry called 'muteigigainen'
無定義概念という,初等幾何学における概念 - EDR日英対訳辞書
A boundary element analysis is performed based on a boundary element method by using an elementary solution having asymmetrical potential distribution geometry so that near singurarity can be prevented, and that the independency of a boundary element equation can be maintained. 非対称なポテンシャル分布形状を有する基本解を用いて境界要素法に基づき、境界要素解析を行ない、近特異性を回避すると共に境界要素方程式の独立性を保つようにする。 - 特許庁
