- 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. 本文用会聚束电子衍射的方法对石英位错进行了测定，同传统的双束法相比较，此方法更为简单和方便。
- This“ signal beam” then meets a separate reference beam, and where the two beams intersect they create an interference pattern in a light-sensitive medium. 然后，信号光会和另一独立的参考光相遇，当两个光束相交时，它们会在感光介质中制造一个干涉图样。
