摘　　要：提出了一种超声波散射式颗粒测量方法,论述了该技术应用的理论基础,并在详细分析其测量原理基础上,指出了在单频率换能器和单散射角下进行颗粒测量时存在着测量结果多值性的可能。给出了解决这一关键技术问题所采取的可能方案和措施。A technique of particle detection based on ultrasonic scattering is presented and its theoretical fundament is discribed. After the measurement principle is analyzed, a multi-solution problem about measuring results when a transducer with the single frequency and a single scattering angle are applied maybe occur. Three ways for overcoming that key technique problem are provided. Sequentially, all measures for further developing the ultrasonic scattering particle detection system are given.
