未来新材料领域展望高温超导线材某种物质当处于该物质的特定温度（临界温度）以下时，该物质的电阻变为零，这种现象称为超导。显示超导现象的某些金属或陶瓷氧化物等材料称为超导材料。虽然金属显示超导现象有的临界温度最高为－２５０℃，但在１９８６年已发现了在临界... Future Prospects for New Materials High Temperature Superconducting Wires A substance whose resistance becomes zero when it is below a specific temperature (critical temperature) of the substance is called superconductivity. Some of the materials that show superconducting phenomena, such as metals or ceramic oxides, are called superconducting materials. Although the metal shows superconductivity some of the critical temperature up to -250 ℃, but in 1986 has been found in the critical ...
