摘要
对二元基阵经电子移相形成单指向性的原理进行了理论分析。并采用三种形状不同的压电材料作为基阵的基元，制作了三种水听器，实验测定结果与理论结果一致，获得较好的单指向性。
The unidirectivity formed in array of two elements with electric phase-shift is theoretically discussed. Three kinds of hydrophone are designed with different elements of array in shape. The experimental and theoretical results are in good agreement.
