我国超声测量技术和标准化发展的三十年

Thirty years of ultrasonic measurement and standardization in China

  • 摘要: 结合作者的研究经历回顾了30年来我国超声测量技术发展历程和标准化的进展,展望了未来的发展趋势。这些进展包括对辐射力天平(RFB)法测量超声功率的主要改进(例如一系列辐射力计算新公式的导出和应用并得到IEC同行的验证认同,还使RFB的适用范围由平面波束拓展到各种聚焦波束,量程从30W提高到500W)、测量水听器的研发和互易校准技术的改进和发展、高强度聚焦超声(HIFU)声功率和声场特性测量技术创新和先进的HIFU国家标准制订以及对IEC标准化工作的推动作用等。

     

    Abstract: The progression of measurement techniques and standardization for basic ultrasonic parameters in China in the last thirty years is expressed by combining author’s research.The further development is looked up.These progresses include the improvement of the method of radiation force balance(RFB),such as a number of new derived formulas of radiation force and their application,which were tested and approved by colleagues of IEC,the expended application area of RFB to various focused beams from unfocused beam and the range up to 500W from 30W,and the developments of measuring hydrophones and of their calibration methods based on reciprocity principle,and the innovation on measurement techniques of acoustic power and field characteristics of high intensity focused ultrasound(HIFU) as well as working out the first national standard of HIFU measurement in the world,promoting the standardization works on HIFU in IEC etc.
