摘要：
The compressibility β of mixed oxides possessing the perovskite-type structure has been evaluated as a function of the composition x. The conditions for different types of the β (x) dependence have been established. Specifically, it should be linear in case of isovalent substitution and may be S-shaped for heterovalent substitutions provided the compositional dependence of the average unit-cell parameter has negative deviation from Vegard's law. © 1990, Taylor & Francis Group, LLC.
