rebound value
解釋
回彈值-
Firstly it discusses the value, meaning, background and method of this topic. then it deducts the single - bubble sound pressure, spectrum of sound pressure, power spectrum. according to the real situation of traveling bubble cavitation noise around a schiebe body, the mathematical model of single - bubble collapse is selected, furthermore, the mathematical model of mass traveling bubbles without interference effect is established, and the multi - peaks and rebound phenomenon while bubbles collapse is also analyzed with statistical method
