讨论了内应变和电荷再分布对四面体配位的{A}、{N}、{B}、{8-N}晶体压电常数的贡献。结果表明，用电荷重分布与键电离度的依赖关系，可以定量地解释压电常数从$N=1和{2}到$N=3的符号反转。
The contributions of internal strain and charge redistribution to the piezoelectric constants of tetrahedrally coordinated ${A}^{N}{B}^{8\ensuremath{-}N}$ crystals are discussed. It is shown that the reversal of sign of the piezoelectric constant on going from $N=1 \mathrm{and} 2$ to $N=3$ can be explained quantitatively in terms of the dependence of charge redistribution on bond ionicity.
