YBa_2Cu_3O_（7－δ）超导陶瓷螺旋谐振器

The Helical Resonator Made of YBa_2Cu_3O_(7-δ)Ceramic Superconductors

用ＹＢａ２Ｃｕ３Ｏ（７－δ）超导陶瓷裸线绕制了一定弹性和强度的螺旋谐振器内导体，整个ＹＢａ２Ｃｕ３Ｏ（７－δ）螺旋是导通和超导的。对比测试了室温和液氮温区下超导螺旋和同样尺寸Ｃｕ螺旋谐振器的品质因数（Ｑ），液氮温区（７７Ｋ、ｌ００ＭＨｚ）下，前者的Ｑ值比后者高３倍，初步显示了ＹＢａ２Ｃｕ２Ｏ（７－δ）高温超导体在这一领域应用的优越性。

A helical resonator used for internal conductor is produced. It is made of YBa2Cu3O(7-δ) ceramic superconductive wire. It is shown to have specific elasticity and strength by the relevant experiments. The YBa2Cu3O(7-δ) helix itrself is ether conductive or superconductive. The quality factore of both the superconductive helix and the cu helical resonatore of the same size, at either the liquid nitrogen temperature or room temperature are investigated. It is discovered that the value of the quality factor of the superconductive helical resonator is three times higher than that of Cu helical resonator at liquid nitrogen temperature(77K, 100MHz). Which shows that the former is a superior resonator in the research of electronic devicee.
