衍射束 meaning in English
diffracted beam
Examples
- The sample should not be so large as to increase unduly the width of the diffracted beam .
样品不应当过分大，以致不恰当地增加了衍射束的宽度。 - For example , if the diffraction pattern is defocused by under - focusing the diffraction lens then the image of the specimen can be seen in both the direct and diffracted beams in the diffraction pattern and , since under - focusing the diffraction lens images a plane above the diffraction pattern , these images will not be inverted with respect to the diffraction pattern
比如，如果衍射模型是通过衍射透镜下焦散焦的，样本的映像就能在衍射模型中直接的衍射束中看到，但是由于衍射透镜下焦在衍射模型之上平面成像，这些映像就不会对应衍射模型倒置。
