| 摘 要： | 针对美国ASTM E1065中提及的脉冲回波法与水听器法,通过在<10MHz频率范围内的实验,比较了这两种方法在评价平面超声探头与聚焦超声探头声场参数的一致性。实验表明,针对超声探头辐射声场参数的测量,在合理选择小球参数的基础上采用脉冲回波法与水听器法具有较好的测量一致性,而水听器法则提供了一种具有量值可溯源的超声探头评价与校准方法。 |

| Abstract: | When the frequency range of ultrasonic transducers is less 10MHz, experimental researches, used the pulse-echo and hydrophone methods introduced in the ASTM E1065, has compared the consistency of two methods for measurement of sound field parameters of the plane ultrasonic transducers and the focused transducers. Used the reasonable diameters of the small balls, the experiments show well consistency of pulse-echo and hydrophone methods for measurement of sound field parameters of ultrasonic transducers, but the hydrophone method is a method of measurement traceability in evaluation and calibration of ultrasonic transducers. |
