| 中文摘要: |
| 文章利用半波长干涉的简单原理制作成高频∞字形指向性传声器,同时应用信号处理技术,形成简易的早期侧向反射声测试系统,在缩尺模型试验中实现早期侧向反射声系数的测量,扩大了缩尺模型试验的功能。 |
| 英文摘要: |
| This paper introduces a measuring method of lateral energy fraction in the scale model experiments.According to the interference principle of half wave length making the high frequency figure 8 directional microphone,which,together with the signal processing technique,form a receiving and analysing system,and then the measurements of lateral energy fraction in the scale model are realized. |
