The fresnel and franhufer diffraction patterns, of regular shapes screen such as slits, rectangular apertures, circle apertures, discs, triangle apertures, ronchi gratings, and some irregular shapes screen, are observed in the different propagation distance. this clearly gives the relation and difference of the two diffraction patterns
具體分析了規則形狀如單縫、矩孔、圓孔、圓盤、三角孔、黑白光柵及一些不規則形狀等孔徑的菲涅耳衍射和夫瑯禾費衍射圖樣強度分佈，為深入理解菲涅耳衍射和夫瑯禾費衍射及其內在聯系與區別提供了理論依據。 -
This is achieved experimentally by focusing the selector aperture on the final screen using the diffraction lens, which is most accurately done after removing the objective aperture, and then ( after replacing the objective aperture ) focusing the specimen using the objective lens only
這已經通過使用衍射透鏡在最終屏幕上聚焦選擇孔實驗性的完成，此方法多數能在移動目標孔后準確完成，然後（重置目標孔后）僅通過目標透鏡聚焦樣本。 -
Interferometirc lithographic technology incorporates laser, interference optics, diffraction optics and optical lithography and it is a frontier research subject in microfabrication technology and microelectronic field sponserd by national natural science foundation of china. the research for this technology in theory, simulation and experiments has important scientific meanings and broad application prospect for promoting lithographic limit, developing nanometer electronic and photoelectron devices, novel large screen panel display and novel lithographic equipment of our country
干涉光刻技術集激光、干涉和衍射光學及光學光刻於一體，是國家自然科學基金資助的微細加工技術和微電子領域的前沿研究課題，對其進行理論、模擬和實驗研究，對推進光學光刻極限，發展我國納米微電子和光電子器件、新型大屏幕平板顯示器和新型光刻機具有重要的科學意義和廣闊的應用前景。 -
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。 -
If the single - slit is replaced by a small hole, because of the diffraction by the small hole, a bright spot appears on the screen surrounded with gradually decreasing bright and dark stripes alternating with each other, for which the intensity distribution is as follows, refer to figure 1 - 2
如果單縫變成小孔，由於小孔衍射，在屏幕上就有一個亮斑，它周圍還有逐漸減弱的明暗相間的條紋，其強度分佈如圖1 - 2所示。 -
An example of this technique is shown in fig. 1. 3 for a particular magnification and diffraction setting where the relative rotation is degrees it is conventional, nowadays, to print all micrographs and diffraction patterns with the emulsion side of the photographic plate upwards and consequently, the rotation obtained from experiments, such as that indicated in fig. 1. 3, is in the same sense as that which appears on the viewing screen
這種技術的一個例子如圖表1 . 3所示，相對的旋轉為度下的一個特定的放大和衍射設定是當前最普遍的，可用於印刷所有的顯微圖和攝影用感光板上的乳劑面的衍射模型，因此，實驗獲得的旋轉，如圖1 . 3所示，和在視圖屏幕上顯示出來的有相同的意義。
