中文摘要:
      本文研究聚焦超声场的辐射力计算.应用几何声学方法,推导了聚焦超声作用于测试靶上的辐射力的通用公式,讨论了全反射靶和全吸收靶上的辐射力.最后给出了应用辐射力法测量高强度聚焦超声装置的声功率的实例,其结果与量热法测得的声功率接近,偏差不大于3%.
英文摘要:
      In this paper the calculation method about radiation force has been studied.The formulas of radiation force acting on targets in the focused ultrasonic field are derived using ray acoustic method.The radiation forces on the totally reflecting target and on the totally absorbing target are discussed.Finally a measured result of acoustic power of a high intensity focused ultrasonic equipment by radiation force method is given.This result is very close to that measured by the calorimetry and the deviation between them is less than 3%
