网络释义
...形成的张角越大，可以进入物镜的光线越多，根据衍射 (diffraction) 理论，这代表点光源因衍射形成的 衍射环 ( diffraction rings ) 很狭窄和集中，衍射的影响小，显微镜的分析能力 (resolving power) 自然提高。

The scattered diffraction pattern and smaller rings were shown in the electronic diffraction analysis through TEM.
其电子衍射具有稀疏的斑点和较少的衍射环。
-
Therefore, instead of incoming light being focused to a perfect geometric point, the diffraction effect spreads the light into a disc with rings surrounding it.
因此，由于衍射存在，我们很难把入射光线集中在一点上，衍射使最终形成一个圆盘或者在外圈形成一个圆环。
-
And the result is a diffraction pattern that produces a series of rings.
