    在水聲數字通信系統中，聲波傳播的多途效應會引起嚴重的碼間干擾，使水下數據傳輸的可靠性和數據傳輸速率都大大的降低。
  9. Before now because operating frequency was low, suppose that electrode in saw device has no thickness and thus second order effects are ignored. these second order effects, including electromagnetic feedthrough, triple transit interference, body acoustic wave, reflection and so on, affect the performance of saw device in high frequency. so it is important that second order effects are researched and improved in depth

    這樣的需求要求了saw設計者考慮在低頻時未加考慮的二階效應，大多數以前的分析假設電極無厚度而忽略了的二階效應（電磁直通、三次行程干擾、體聲波、聲電再生等）在高頻時對saw器件的性能影響較大，要求對其二階效應進行深入研究並對其進行改善。
