备  注：摘要：We first give a short review of results on the low Mach number limit for the compressible magnetohydrodynamic equations with viscosity and/or magnetic diffusivity. Then, we study the incompressible limit of the compressible non-isentropic ideal magnetohydrodynamic equations with general initial data in the whole space $R^d$ ($d=2,3$), and establish the existence of classic solutions on a time interval independent of the Mach number. Finally, by deriving uniform a priori estimates, we obtain the convergence of the solution to that of the incompressible magnetohydrodynamic equations as the Mach number tends to zero.
