论文摘要
如果不淬火，超导体是稳定的。淬火是一个短期的物理问题。为了深入了解以及如何避免淬火，必须分析稳定性背后的物理学。先前建议的动态弛豫模型被重新考虑并应用于Ybacuo 123和BSCCO 2223高温，薄膜超导体。与这项研究并行，使用电阻网络（A细胞模型）的非常规方法来介绍一种方法，如何估计在电阻测量中，可以确切确定超导体的临界温度的确切确定程度。在考虑其数值收敛行为时，在侧面结果中，可能会提供（至少对）电阻率与温度曲线的弯曲（至少有贡献）的替代解释，也许也可以替代对这些曲线的热波动影响的标准解释。 动态放松和阻力模型提供了括号，该括号与金茨堡 - 兰道顺序参数相关联，（i）解决超导体稳定性问题的解决方案（本文的主要目的），并试图解释（ii）在临界温度和（III）与热效应的预测的电阻率曲线（II）。
A superconductor is stable if it does not quench. Quench is a short-time physics problem. For its deeper understanding of, and how to avoid quench, the physics behind stability has to be analysed. A previously suggested dynamic relaxation model is re-considered and applied to YBaCuO 123 and BSCCO 2223 high-temperature, thin film superconductors. Parallel to this investigation, an unconventional approach using an electrical resistance network (a cell model) is applied to introduce a method how to estimate the extent by which, in resistance measurements, exact determination of critical temperature of superconductors is possible. This resistive cell model, when considering its numerical convergence behaviour, in a side result may provide an alternative explanation of (at least a contribution to) bending of resistivity vs. temperature curves, and perhaps also an alternative to standard explanations of the thermal fluctuations impact on these curves. The dynamic relaxation and the resistance models provide a parenthesis that correlates, in terms of the Ginzburg-Landau order parameter, (i) solution of superconductor stability problem (the main objective of this paper), with tentative explanation of (ii) bending of the resistivity curves near critical temperature and (iii) with predictions from thermal fluctuations.
