摘要
本文研讨了Ｈａｒｔｅｎ等人提出的高阶精度基本不振荡格式ＥＮＯ［１，２］，给出一种构造一致三次分段插值多项式函数Ｒ（Ｘ，Ｗ），叫以及四阶ＥＮＯ格式的方法，并在理论上证明了如此构造的格式是基本不振荡的一致三阶守恒型格式。
ENO schemes by Harten[1,2] are studied in this paper. A method which constrUCt a uniformly three-order piecewise polynomial function R(x; w) of x as four-order interpolant polynomial funCtion and four-order ENO schemes are given. The schemes is proved theoretically uniformly three -order accurate essentially non -oscillatory one in conservation form.
