众所周知,流过一超导体的电流超过某一临界值后,超导体呈现电阻。若把一软超导带(即临界磁场或临界电流较低的超导带)与一硬超导板紧密相近时,临界电流值会增加。达是因为平常在超导膜中的电流密度以边缘上最高,并且当它所载电流超过临界
It is well known that superconductors exhibit electrical resistance when the current flowing through a superconductor exceeds a certain critical value. If a soft superconducting tape (ie, a critical magnetic field or critical current lower superconducting tape) and a hard superconducting plate close to the value of the critical current will increase. The reason is because the current density in the superconducting film is usually the highest on the edge and when the current it carries exceeds the critical
