| 摘 要： | 基于镜像原理,推导出组合声源在有限空间中的指向性公式,并运用Matlab软件进行模拟.结果表明,与无限大障板情况相比,基于镜像原理的组合声源远场指向性更能真实反映声化学反应器内声场的分布.

| Abstract: | To derived the directivity formula of the built_up sound source in a limited space is derired based on principle of mirror image and is simulated with Matlab.Compared with the far field directivity on infinite barrier plate,the result indicates that the directivity of built-up sound source based on principle of mirror image exhibits more actually the distribution of sound field in sonochemical reactor. |
