| Abstract: | 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. |
