中文摘要: |
本文以无限大障板活塞辐射为声源模型,对声源指向性在使用悬链浮子式超声功率计测量时产生的误差进行了理论探讨,并针对具体的几个实例进行了数值计算给出相应的修正值。 |
英文摘要: |
The influence of transducer directivity characteristic on the ultrasonic power measurement with a tethered float ultrasonic power meter has been studied theoretically by using a model of the infinitebaffle piston. The correction data in some exaples calculated by numerical method are presented in this paper |
