Eno schemes are based on the approximation theory, which achieve high - order spatial accuracy by reconstructing piecewise smooth high - order approximate polynomial from the cell - averaging values. during the reconstruction, adaptive stencil technology, which automatically chooses the relatively smoothest stencil from all possible stencils, is adopted to guarantee essentially non - oscillation near the discontinuity
Eno格式基於近似理論，採用自適應基架技術（即自動選取所有基架中相對最為光滑的基架） ，對網格平均值構造分段光滑的高階多項式來獲得高階空間精度，同時保證格式在間斷附近具有基本無振蕩性質。
