摘要
本文中,首先概述了超导体的概念。然后,按照超导体的微观模型,用量子场理论得到超导体激发态。最后,指出该方法满足的条件。
In this paper,we first summarised the concept of Su'perconduct'ors. And then,we derived the excited states of superconductors by using the microscopical model of superconductors and the quantum field theor 'y. Finley,we Pointed out the nec'essary condition in which this method works.
