摘　　要：基于交错网格上的重构和将交错网格转化为非交错网格,构造了二维理想磁流体力学方程的二阶非交错无振荡中心差分格式.给出两个典型数值算例,验证了格式的有效性.Based on reconstructions on staggered grids and converting staggered grids into non-staggered grids,a class of two-order non-oscillatory central difference schemes with non-staggered grids for the two-dimensional ideal magnetohydrodynamics equations is obtained.Two typical numerical examples are given to verify the validation of the resulting schemes.
