摘要
辐射压力法是超声功率测量中常采用的方法,用辐射压力法测量声功率中对于不同反射靶面的功率与压力之间的换算关系是非常重要的。文章从能量守恒基础出发,推导了大口径聚焦换能器声场作用于锥面反射靶的功率与压力的换算关系,并将结果应用于凹锥面反射靶计算。
In the ultrasound power measurement of ultrasound transducer, the radiation pressure method is often used. To calculate the converting relationship between the ultrasound power and the pressure of interceptor is very important. Based on the energy conversation law, it is deduced the converting relationship between ultrasound power and the pressure formed by ultrasound beam from large-aperture focused transducer in this paper. The result is applied to the calculation of concave cone reflector.
