摘　　要：以超流体的二流体模型为基础,根据超流的微观理论,找到了一个能量-动量张量,并通过能量和动量守恒定律导出了相对论性超流体的宏观动力学方程.在非相对论极限下,将其与非相对论性超流体的动力学方程作了比较,符合得很好.另外还讨论了相对论性超流体中的涡旋量子化.进一步讨论了存在引力场时的情况.Based on two-fluid model of superfluid,an energy-momentum tensor has been discovered,and the relativistic equations of superfluid dynamics have also been derived according to the laws of conservation of energy and momentum for the physical system.In the non-relativistic limit,they were compared with the non-relativistic ones.The quantization of vortices has also been discussed in the relativistic superfluid in this paper.The equations of relativistic superfluid dynamics have been discussed further in the pr...
