在温度、外界磁场强度和电流密度都小于临界值的条件下,具有导电时电阻和内部磁感应强度为零的性质的材料叫超导体。常温(300K 或27℃)超导体的研制成功,引起了世界各国的巨大反响,对军事领域产生极为深远的影响。超导聚能武器聚能武器是把能量汇聚成极细 Under the condition that the temperature, the external magnetic field strength and the current density are both smaller than the critical value, the material with the property that the resistance and the internal magnetic induction intensity are zero at the time of conduction is called a superconductor. The successful development of superconductors at room temperature (300K or 27 ℃) has aroused great repercussions from all over the world and has far-reaching impact on the military field.
