尽管众所周知，短路匝会极大地破坏超导绕组的性能，但（据我们所知）这个问题在文献中并未得到适当讨论。我们对超导绕组内部存在短路匝的后果进行了分析。主要结论如下：此类绕组在充电过程中可能会过早失超，因此可接受的充电速率应该非常低；此类绕组也可能在计划放电期间失超；并且在失超的情况下，大量存储的磁能不能有效地从短路绕组中排出。
Though it is widely known that short-circuited turns can considerably spoil the performance of superconducting windings, this problem (to our knowledge) was not properly discussed in the literature. We performed an analysis of the consequences of the presence of shorted turns inside superconducting windings. The main conclusions are as follows: such windings can undergo premature quenches during their charging, therefore the acceptable charging rates should be very low; such windings can also quench during their planned discharge; and a considerable amount of the stored magnetic energy cannot be effectively evacuated out of a short-circuited winding in the case of its quench.
