These are tiny pieces of a superconductingmaterial consisting of a niobium film on an aluminium oxide wafer with gaps etched into it.
这是一些细小的超导材料，由一个刻有间隔的氧化铝晶片上的铌薄膜构成。

The material has high (100) axial orientation, which can be widely applied in catalysts, optical materials, superconducting materials and other fields.
它具有高度的（100）轴取向，可广泛地用于催化剂、光学材料 和超导材料等领域。

But once the intensity crossed a certain threshold the researchers discovered that larger regions of order began to emerge and, as a result, the material became superconducting.
