摘　　要：探讨了理想磁流体力学中的相对论性Kelvin圈积分定理。相对论性Kelvin圈积分定理是指温度涡旋在圈积分下是一个守恒量。首先简略的回顾了相对论重离子碰撞中的理想磁流体力学相关结果。本文的核心是推导出理想磁流体力学中的相对论性Kelvin圈积分定理的表达形式。同时,也将已知的理想磁流体力学的解析解运用到该定理上。这一主要结果也可以运用到相对论重离子碰撞中磁流体力学的研究中。We have studied the relativistic Kelvin circulation theorem for ideal Magnetohydrodynamics.The relativistic Kelvin circulation theorem is a conservation equation for the called T-vorticity,We have briefly reviewed the ideal magnetohydrodynamics in relativistic heavy ion collisions.The highlight of this work is that we have obtained the general expression of relativistic Kelvin circulation theorem for ideal Magnetohydrodynamics.We have also applied the analytic solutions of ideal magnetohydrodynamics in Bjorken flow to check our results.Our main results can also be implemented to relativistic magnetohydrodynamics in relativistic heavy ion collisions.
