补充资料：BCS穿透深度（BCSpenetrationdepth）
BCS穿透深度（BCSpenetrationdepth）
对纯超导体，由BCS电流方程，在伦敦极限下（`\xi_0\lt\lt\lambda`或$l\lt\lt\xi_0$）的穿透深度与伦敦穿透深度λL(T)相符。对非纯超导体（含杂质），在伦敦极限下为
$\lambda(T)=\lambda_L(T)(1 \xi_0//l)^{1/2}$
一般地，λL(T)由经验公式表示其与温度T的关系（见“伦敦穿透深度”）。在皮帕德极限下（$\xi_0\gt\gt\lambda$或$\xi_0\lt\ltl$），ξp=ξ0，则给出为
$\lambda(T)=\frac{8}{9}\lambda_L(T)[\frac{sqrt3\xi_0}{2\pi\lambda_L(T)}]^{1/3}$
