本文研究了具有一般初值的一维非等熵可压缩平面磁流体动力学流动，其在远场x →±∞处的行为是不同的.系统的低马赫数限制是严格合理的。该极限依赖于对加权时间导数的一致估计和一个广义的收敛引理.
This paper is concerned with a one‐dimensional nonisentropic compressible planar magnetohydrodynamic flow with general initial data, whose behaviors at far fieldsx→±∞are different. The low Mach limit for the system is rigorously justified. The limit relies on the uniform estimates including weighted time derivatives and an extended convergence lemma.
