摘要
文章利用边界点法，对振动体外部声辐射在特征频率处解的非唯一性问题进行了研究。文中对非唯一性问题的产生作了说明，并以脉动球和摆动球作为算例，说明了边界点法能够有效地克服在特征频率处解的非唯一问题。
In this paper, the boundary point method(BPM) is applied to the study of the non unique solution at characteristic frequency for exterior acoustic radiation caused by vibrating body.The phenomenon of non uniqueness problem is demonstrated.Taking pulsating sphere and ocillating sphere as examples,it's revealed that the BPM can overcome the non uniqueness problem effectively.
