摘　　要：用自适应Newton插值,结合自适应模型和重构思想去构造数值流通量,对时间采用Runge-Kutta型离散,得到一类不需“真正”插值和数值微分过程的ENO格式。该格式易于数值实现,数值试验表明,这类格式具有良好的计算结果。In this paper, some methods to construct the numerical flux in ENO Essentially Non-Oscillatory schemes for conservative difference equations, which are based on the idea of adaptive stencil and reconstruction, are presented. Some numerical results are also given.

关 键 词：守恒方程 双曲型方程 本质非振荡
