摘要
众所周知,自然界的许多物体都会受到磁场的影响.本文构造了新的泛函关系并结合各种不等式证明了热传导率为零的完全可压缩磁流体动力系统的光滑解在T^(3)中的一致正则性,强解的一致正则性在粘性极限的消失和强解的存在性中有着重要的作用.
As is well known,many objects in nature are affected by magnetic fields.In this paper,we construct new functional relationships and combine various inequalities to prove the uniform regularity of smooth solutions for completely compressible magnetohydrodynamic systems with zero thermal conductivity in T^(3).The uniform regularity of strong solutions plays an important role in the vanishing viscosity limit and existence of strong solution.
