【摘要】 本文从超导网络相变基本方程出发，研究了基元回路为多种长宽比的矩形网络的相边界，得到网络的相边界曲线是磁通量（即磁场Ｈ）的周期函数，而一个周期内的相边界曲线具有镜像对称性．网络的临界温度Ｔｃ（Ｈ）在镜像点处具有极大值．更多还原

【Abstract】 Studied in this paper, is the question about the phase boundary of superconducting network which is composed of various rectangle unit loops from the basic equation of the network phase transition. It is found that the phase boundary curve of the networks are periodic functions of the magnetic flux (i.e.external magnetic fieid H ), and while the phase boundary curve of a period is mirror symmetric. The critical temperature T c(H) of the network is corresponding to maxima values when the curve is located in mirror symmetric point.更多还原
