摘要
铁电１８０°畴结构在超声波作用下将被诱导出铁电畴层波。在平行于畴壁的两个表面上，铁电畴层波电势数值不相等，在两表面之间有电势差，它提供了一个电动势。
Ferroelectric domain layer wave (FDLW)will be induced by the ultrasonic wave in ferroelectric 180° domain structure.At the two surfaces parallel to the domain wall,the electric potentials aren′t equal in numerical value,there is a potential difference between the two surfaces,and it will provide a electro motive force.This is valuable in ultrasonic control and acoustoelectric transform
