摘要：

The T-C: of BamuSr1-muTiO3(BST) as a function of the composition and the lattice parameter gamma is examined. It is corn pared with the lattice parameter dependence of Te of BaTiO3 and SrTiO3 respectively. It is argued that the variation of Te in BST can be attributed to the change of cell volume. The order and the diffuseness of the phase transition are also discussed from the volume effect viewpoint. The fact that the Ba and Sr are ionized leads to the volume effect of BST.
