摘要：

Anomalous wide angle X-ray scattering (AWAXS) is used to investigate the short and medium range order in Sr silicate and Sr aluminosilicate glasses. Strong Sr-Sr correlations at 4 Angstrom are found in the silicate glass, whereas they are much weaker in the presence of aluminium. The first Sr-O distance and coordination number and further Sr-Sr distances in the silicate glass are consistent with edge sharing octahedra. The Sr-AL correlations cannot be exactly determined, but the role of charge compensator imposed on the Sr by tetrahedral Al3+ rapidly reduces the order found in the silicate glass.
