lens pattern 中文意思是什麼
lens pattern
解釋
鏡片成形器,鏡片模型-
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，如果衍射模型是通過衍射透鏡下焦散焦的，樣本的映像就能在衍射模型中直接的衍射束中看到，但是由於衍射透鏡下焦在衍射模型之上平面成像，這些映像就不會對應衍射模型倒置。 -
Electrons which pass through the thin specimen are brought to a focus in the back focal plane of the objective lens, this lens, like all electromagnetic lenses, acts as a converging lens and thus forms a diffraction pattern in this b. f. plane
穿越薄樣本的電子被帶到目標透鏡背面焦點平面的一個焦點，這個透鏡，象所有的電子透鏡一樣，充當了聚焦透鏡的作用，因此，構造了在這個背面焦點平面的衍射模式。 -
Without lens, the scattering pattern caused by the dust particles contamination on the lens surface was avoided
另外，由於該測徑儀不使用透鏡，還避免了由於透鏡受污染而引起的雜質衍射對測量的干擾。 -
An inverted image is formed in the first image plane and the three subsequent lenses in the namely the diffraction lens, the intermediate lens and the projector lens are used either to magnify this image or to magnify the diffraction pattern
在第一映象平面出現一個倒的圖象，隨后的第三透鏡也就是衍射透鏡，中間的透鏡和投影透鏡被用來放大圖象或者放大衍射模式。 -
In addition to the rotation associated with the reduction in the strength of the diffraction lens there can also be an inversion between the diffraction pattern and the corresponding micrograph
除了通過衍射透鏡磁力縮減取得的旋轉，還可以有一種衍射模型和對應的顯微圖之間的倒置。 -
As mentioned above, to image the diffraction pattern it is necessary to reduce the power of the diffraction lens by altering the current through the lens coils from the value used to form an enlarged image of the first image
如上所言，要成像衍射模型就必須縮減衍射透鏡的能量，通過改變從已有形態到形成第一映像的放大映像過程中穿過透鏡圈的能量實現。 -
Since magnetic lenses produce an image rotation that is related to the strength of the lens, then it is clear that there will be a relative rotation between the diffraction pattern and the corresponding electron micrograph
由於磁性透鏡通過透鏡的磁力產生一個映像旋轉，然後很明顯的，在衍射模型和相應的電子顯微圖之間就會產生一個相關的旋轉。 -
Whether the 180 inversion appears in the relation between the electron - optical image, i. e. the micrograph, and diffraction pattern seen on the final screen, depends on the number of inversions that the image and diffraction pattern undergo by the lenses following the objective lens in the microscope column
電子光學映像比如顯微圖和最終屏幕所見衍射模型之間180度倒置的出現是否有聯系，取決于顯微鏡柱中目標通過透鏡產生的映像的倒置數量。
