摘要
根据BaTiO3的吉布斯自由能展开式，讨论了对称群Oh操作的所有不可约表示，考虑到不同不可约表示项的相互作用，并利用相稳定条件，推导出可能对称相的温度曲线。
The invariants of all the irreducible representations of group Oh are discussed, based on the Gibbs free energy expansion of BaTiO3. In consideration of the mutual effect between the terms belonging to the different irreducible representations and by using the stability conditions of the phases, the temperature regions of the possible phases are calculated.
