摘要：

We have measured the a.c. conductivity of fully oxygenated and oxygen deficient polycrystalline and single crystal Y-Ba-Cu-O samples. We find no evidence for a frequency dependent conductivity in the frequency range d.c. to 1 GHz. We also measured the dielectric constant K for oxygen deficient samples. While the single crystal shows a low K, the polycrystalline samples show a very large K (K600), which we ascribe to capacitive coupling between grains.
