摘要
对对流方程ut＝aux构造一族含双参数的三层差分格式，当参数α=1／2，β=0时得到双层格式．这些格式对任意非历参数均为绝对稳定的，其局部截断误差为0（Δt2＋Δx4）．
A class of new three-layer difference sehemes containing biparameters are constructed for convective equation Ut=aUx A double-layer scheme will be obtained in case α= 1/2,β=0. These schemes are all absolutely stable for arbirarily nonnegative parameters, with local truncation error of O(Δt2+Δx4).
