空心超导球体（hollowsuperconductingsphere）空心超导球体（hollowsuperconductingsphere）设内外半径分别为r1和r2(r1≤r≤r2)，壁厚d=r2-r1的第一类超导体的空心球体处于外磁场强度H0中。令ζ=r/δ，Δ=d/δ，δ=δ0/ψ，δ0为大样品弱磁场穿透深度，ψ是有序参量。设H1和M分别是空腔中磁场强度和样品磁矩。按GL理论，徐龙道和Zharkov给出的部分主要结果如下：`\zeta_1\gt\gt1`和$\Delta\gt\gt1$时，H1=6H0ζ2ζ1-2e-Δ，M=-H0r23(1-3δ/r2)/2所以对厚壁样品，腔内H1≈0，只要H0低于临界磁场，球壳层可视为磁屏蔽物，样品可利用为磁屏蔽体。对$\zeta_1\gt\gt1$和$\Delta\lt\lt1$的情形，则H1=H0/(1 ζ1Δ/3)，M=-H0r23[1-1/(1 ζ1Δ/3)]/2可见，若$\zeta_1\Delta\gt\gt1$，则$H_1\lt\ltH_0$或H1≈0。所以，虽然$d\lt\lt\delta$，但磁场仍被屏蔽而很难透入空腔，称ζ1Δ/3为空心超导球体的屏蔽因子。相反，$\zeta_1\Delta\lt\lt1$，则H1≈H0，球壳层几乎不起屏蔽磁场的作用。对M讲，也可作同样讨论。此外，类似于实心小样品，也可求出各种临界磁场HK1，HK，HK2和临界尺寸等。
