对柱状声源声辐射逆问题的探讨

摘要

对细长柱状声源的声辐射逆问题进行了探讨.其主要思想是：把柱状声源所产生的声场中的声压表示为一组独立函数的线性组合，这样根据声场中声压分布就可以求解细长柱状声源的声辐射逆问题.文中运用无限长脉动圆柱算例进行了验算.结果证明，本文进行的探讨是可行的.%It discusses the inverse acoustic problem of slight cylinder source. Its main idea is that we can resolve the inverse acoustic radiation problem of cylinder source using a few points of field pressures when we express field pressures in one field with linear combination of cylinder wave functions. It uses an infinite long dilating as an example. The result shows that the research in this paper is feasible.
