摘　　要：通过结合求解双曲型守恒律的5阶紧凑CWENO格式和半离散中心迎风格式,推广应用于求解一维理想磁流体力学方程,得到计算一维理想磁流体力学方程的5阶紧凑CWENO中心迎风格式.The fifth-order compact CWENO reconstruction scheme and semi-discrete central-upwind scheme for the hyperbolic conservation laws were combined to produce a fifth-order compact CWENO central-upwind scheme to solve the one-dimensional ideal MHD equations. Numerical experiments illustrated that the fifth-order compact CWENO cen-tral-upwind scheme has the properties of high resolution and stability for one-dimensional idea MHD equations.
