摘要：

Anomalous Wide Angle X-Ray Scattering (AWAXS) has been applied to glassy bulk WO3. In this system the partial distribution of pairs W-W and W-O may be reliably extracted. Glasses have been prepared by non-reactive grinding from both the metastable pyrochlore type structure and from the hydrates WO3 . nH(2)O. A weighted differential analysis has been developed, leading to the knowledge of the oxygen surrounding and to the extraction of the partial W-W first correlations. The influence of water content on the octahedra's network in the amorphous states is analyzed and the medium range order are considered in the framework of hexagonal, pyrochlore and ReO3 type structures.
