在此基础上采用导波的模式展开分析方法, 给出了与管间界面特性及激励源密切相关的周向超声导波模式展开系数的解析表达式. 数值分析了管间界面特性的变化对周向超声导波的频散和声场所产生的影响.
And based on which, the guided waves mode was used as analytical method to conclude the analytical expression of  expansion coefficient of circumferential ultrasonic guided wave mode, which was closely related to interfacial characteristics between tube and excitation source.
Besides, the effects of  changes of  interfacial characteristics to dispersion and the acoustic field of ultrasonic guided wave were analyzed based on numerical analysis.
