摘要 在朗道理论基础之上,将方硼盐的自由能始终看成自发极化矢量的3个分量p1,p2,p3的函数,利用极值条件和稳定性条件求出了方硼盐所有可能的铁电相,计算了各个铁电相可能存在的温区. On the basis of Landau theory, the free energy of boracites is regarded as the function of the three components p1, p2, p3 of the spontaneous polarization. All the possible proper ferroelectric phases and the temperature regions exiting are calculated.
