摘要
采用叉指换能器的脉冲响应模型，建立了三指群和四指群分组单指无内反射结构换能器的脉冲响应解析表达式，并在此基础上通过付氏级数分解，分析了该结构的频谱特性，最后给出了实验验证结果．
The analytical expressions of pulse response of a grouping single-finger transducerwithout internal renection are established in 3-finger and 4-finger group using a model of pulse response of interdigital transducer,and through decomposition of the Fourior progressions,the spectral characteristics of the transducer structure are analyzed.At last,the experimental results aregiven in the paper.
