| 摘 要： | 以MgB2为例，用两带各向异性Ginzburg-Landau理论分析了两能隙超导体的磁通量子化现象，总的来说，两能隙超导环内的磁通是磁通量子的整数倍，两带对应的磁通线根数相同，且一根σ带磁通线与一根π带磁通线所携带的磁通之和为一个磁通量子。

| Abstract: | Taking MgB2 as an example, with the two-band anisotropic Ginzburg-Landau theory, this paper analyzes the Mag-netic flux-quantization of two-gap anisotropic superconductor .The magnetic flux of two-gap superconducting ring contains integral flux quanta .The numbers of two bands corresponding to the lines of magnetic flux are the same .The sum of the magnetic flux car-ried by one line of magnetic flux of σ-band and π-band equals to only one flux quantization . |
