This spring marked the 100th anniversary of the discovery of superconductivity – the ability of materials to carry electrical current with no loss. Currents set up in superconducting wires can exist for years without any measurable decay.
此举也成为了超导现象100周年纪念的标志性事件。所谓超导，就是物质携带电流却不造成损失的能力。超导线中的电流可以存在数年都不出现可测量的衰减。
