我们提出了一种替代的解释，以振荡的通量流动阻力发现在几个先前发表的实验与bi2sr2cacu2o8 + y堆。以前的作者认为，每两个本征约瑟夫森结增加一个涡旋所需的场对应的振荡周期与一个移动的三角形涡晶格（cid:1）的非相模式（cid:2）有关，而每一个结增加一个涡旋对应的周期是由于正方形晶格（cid:1）的同相模式（cid:2）。相反，我们表明两种类型的振荡都可能发生在单层约瑟夫森结中，因此上述解释是不一致的。
We propose an alternative explanation to the oscillations of the flux-flow resistance found in several previ-ously published experiments with Bi 2 Sr 2 CaCu 2 O 8+ y stacks. It has been argued by the previous authors that the period of the oscillations corresponding to the field needed to add one vortex per two intrinsic Josephson junctions is associated with a moving triangular lattice of vortices (cid:1) out-of-phase mode (cid:2) , while the period corresponding to one vortex per one junction is due to the square lattice (cid:1) in-phase mode (cid:2) . In contrast, we show that both type of oscillations may occur in a single-layer Josephson junction and thus the above interpretation is inconsistent.
