摘要：

We have performed reflectance measurements on the (001) surfaces of twinned single crystals of NdBa2Cu3Ox. The oxygen concentration x was varied between 6 less than or equal to x less than or equal to 7. The results were compared to former investigations on YBa2Cu3Ox. The different dependence of the electronic transport properties on the oxygen content of both compounds can be explained by the different distributions of oxygen amongst the Cu-O chains.
