超导材料的发展和应用前景

Discuss the development and application of superconducting materials

超导材料是一种具有超导特性的新型材料,它在一定低温条件下能排斥磁力线并且呈现出电阻为零的现象。超导材料由于具有零电阻、完全抗磁性和超导隧道效应等优异的特性,高温超导材料的用途非常广阔,大致可分为三类:大电流应用、电子学应用和抗磁性应用。大电流应用即超导发电、输电和储能;电子学应用包括超导计算机、超导天线、超导器件等;抗磁性主要应用于磁悬浮列车和热核聚变反应堆等。

Superconducting materials is a superconducting properties of new materials,it can exclude a certain low temperature conditions and the magnetic field lines showing zero resistance phenomenon.Superconducting material with zero resistance,completely anti-magnetic and superconducting tunnel effect,excellent features,the use of high temperature superconducting materials is very broad,can be broadly divided into three categories： high-current applications,the application of electronics and anti-magnetic application.High current applications,superconducting power generation,transmission and storage;electronics applications include superconducting computer,superconducting antennas,superconducting devices;the diamagnetism mainly used in maglev trains and thermonuclear fusion reactor.
