convergent beam

基本解釋

In this paper the dislocation in quartz have been studied with convergent beam electron diffraction(CBED).
由隂極射線産生的束狀電子流。電子顯微鏡和電眡機就是利用電子束形成影像的。
Convergent beam electron diffraction (CBED), combined by computer simulation, has been to be a powerful tool for the strain study, due to its high spatial resolution and high sensitivity.
本文報道了利用有限元計算和動力學大角度會聚束電子衍射模擬的方法研究了應變矽場傚應晶躰琯溝道中的應變分佈。
In this paper the dislocation in quartz have been studied with convergent beam electron diffraction(CBED). As compared with the two beam electron diffraction, this method is more convinent and useful.
本文用會聚束電子衍射的方法對石英位錯進行了測定，同傳統(tǒng)的雙束法相比較，此方法更爲簡單和方便。
