摘　　要：采用全特解场边界元方法求解声辐射逆问题 ,这种方法不需要变量插值、积分求解及奇性处理 ,因而计算量大幅度减少 ,且计算精度高。本文还从辐射声场的情况来探知声源的振动特性 ,这对噪声的主动控制及低噪声结构优化设计有着很大的意义 。Inverse acoustic radiation problem is resolved by using all particular solutions boundary element method,this method doesnt need variable insertion?integral solution and odd processing,so calculation is reduced greatly and precision is high.Vibration characteristic of acoustical driver is ascertained from the condition of radiation acoustical field,it has immeasurable meaning for noise active control and noiseless structure optimum design,it provides direct proof for noise diagnosis.
