| Abstract: | The paper, based on the acoustic theory, analyzes the relationship between the energy from the source of acoustic radiation and frequency, and that between the clusters of sound propagation and frequency. It also discusses the acoustic attenuation, the nature of its propagation through inhomogeneous media, the Doppler Effect caused by sound source against media motion and its applications. It further summarizes the theory of carrying and conveying the internal information by ultrasonic and introduces Ultrasonography imaging and its development. |
