摘要
利用Ｂ－样条函数．文中发展了一个对流扩散方程欧拉－拉格朗日方法的插值格式．改善了其数值频散性。算例表明，此格式优于一次和二次插值格式。文中给出了Ｂ－样条插值格式的二维及三维推广。
Using cubic B-spline function. we developed a interpolation scheme for Ether - Lagrangian method for conviction dispersion equation. which can reduce error short wave efficiently. The two -dimensional and three -dimensional B-spline interpolation scheme are presented also
