emergent wave 中文意思是什麼
emergent wave
解釋
出射波-
The propagation velocity of ultrasound in patient ' s shinbone can be achieved by figuring out the time span between emergent wave and echo wave
根據相關公式,只需計算出超聲波發射信號和回波信號的時間差,即可獲得定量超聲波在受試者脛骨的皮質骨中傳播速度。 -
According to the principle of ultrasound detection, this thesis describes a high - speed sampling system for ultrasound emergent wave and echo wave
摘要根據定量超聲波檢測原理,闡述了一種針對超聲波發射信號和回波信號的高速採集系統。 -
And this result is extended to the eigenfunction of maxwell ' s equations. then the mode series of step index planar dielectric waveguide and circular optical fiber are studied, including propagation modes and radiation modes. as application, there are three examples : the emergent wave from planar waveguide to free space, the transverse and longitudinal coupling of waveguide and the measurement of scalar gratings
由於從一個空間到另外一個空間的光束傳播伴隨著界面上各個模式能量之間的耦合,作為應用,本文介紹了完備性在三個情況下的應用:平面波導出射光束的衍射性質、波導的橫向和縱向耦合以及標量光柵的測試。
