  • 回波
  • 回聲波

Examples

  • Echo waves and their stability in linearly coupled oscillators
    線性耦合振子中的回聲波及其穩(wěn)定性
  • According to the principle of ultrasound detection , this thesis describes a high - speed sampling system for ultrasound emergent wave and echo wave
    摘要根據(jù)定量超聲波檢測(cè)原理，闡述了一種針對(duì)超聲波發(fā)射信號(hào)和回波信號(hào)的高速采集系統(tǒng)。
  • The propagation velocity of ultrasound in patient ' s shinbone can be achieved by figuring out the time span between emergent wave and echo wave
    根據(jù)相關(guān)公式，只需計(jì)算出超聲波發(fā)射信號(hào)和回波信號(hào)的時(shí)間差，即可獲得定量超聲波在受試者脛骨的皮質(zhì)骨中傳播速度。
  • High frequency ground wave radar for near ocean inspection and ocean remote sensor is a method that use ocean echo wave dopier spectrum to deduce the parameters of ocean situation
