本文导出了TE/sub 011/模介质谐振器和TE/sub 011/模圆形谐振腔的微扰公式，以便由谐振频率和无载Q的测量值确定超导体的表面阻抗z/sub s/。使用这些公式在8.7、10.4和23.7 GHz下测量了直径为30 mm的YBCO板的Z/sub s/值。测量结果作为温度的函数。&lt;<ETX>&gt;
Perturbation formulas for a TE/sub 011/ mode dielectric resonator and for a TE/sub 011/ mode circular cavity are derived to determine the surface impedance, z/sub s/, of superconductors from measured values of resonant frequency and unloaded Q. The Z/sub s/ values for a YBCO plate with a diameter of 30 mm were measured at 8.7, 10.4, and 23.7 GHz using these formulas. The measured results are presented as functions of temperature.<<ETX>>
