摘要：

The oxygen content and resulting average oxidation state of copper in YBa2Cu3O7-delta samples (delta = 0.10-0.45), were determined by two gravimetric methods as well as by iodometric titration. The results obtained by the simple gravimetric method and by iodometric titration agree well with each other but the hydrogen reduction method tends to give a somewhat higher oxygen content.
