  1. The sample should not be so large as to increase unduly the width of the diffracted beam.

    樣品不應當過分大，以致不恰當地增加了衍射束的寬度。
  2. It diffracts the diffracted beam which effectively means that it generates an inverse transform.

    它對衍射光束再發生衍射，這實際上意味著它產生了一個逆變換。
  3. Amazingly enough, a beam of electrons had thus been diffracted in a manner completely analogous to a light wave bouncing off a reflection grating.

    一束電子波衍射的方式，同光波從一個反射光柵上彈回的方式完全類似，這真是不可思議。
  4. Our study shows that the optical potential of the diffracted light of the semi - gaussian beam is far higher than that of the evanescent - light wave, and its maximum normal velocity of the incident atoms can be far grater than that of the evanescent - light wave under the same parameters, so the blue - detuned semi - gaussian beam, as a novel atomic mirror, can be used to efficiently reflect atoms with a normal velocity of greater than 1 m / s

    研究表明，半束蘭失諧高斯光束衍射光場的光學勢遠大於消逝波光場的光學勢，在同樣的參數條件下，入射原子的最大速度也比消逝波光場的大，所以作為一種新穎的原子反射鏡，半束蘭失諧高斯光束可以被用來有效的法向速度大於1m s的入射原子。
  5. On the other hand, the electric field and intensity distributions of the he11 mode in the hollow fiber are calculated by using the exact solutions of maxwell equations based on the vector model, and the diffracted near - and far - field distributions of the he11 - mode output beam under the fresnel approximation are studies. we derive an analytical expression on the far - field distribution of the he n - mode output beam in free space and discuss its applicable condition. we also analyze and compare the differences between the he11 - and lp01 - mode output beams, and find that the near - field distribution of the lpoi - mode output beam is a gaussian - like one, but the near - field distribution of the he11 - mode output beam is a doughnut - like one, whereas the far - field distribution of both the lp01 - and he11 - mode output beams are a doughnut one

    此外，我們把中空光纖中lp _ （ 01 ）模（標量模型）和he _ （ 11 ）模（矢量模型）的場分佈以及它們各自的輸出光束的近場與遠場分佈進行了比較，發現兩種模式的輸出光束在近場分佈有很大的區別， lp _ （ 01 ）模輸出光束在近場是一個高斯分佈，而he _ （ 11 ）模輸出光束在近場是一個中空光束，在遠場兩種模式的輸出光束分佈是基本一致的，這正是由於在中空光纖中採用了弱波導近似以後所引起的誤差。
  6. The paper is concerned with the eigen functions of optical fields in dielectrics, the theories of optical waveguide eigen mode, the characteristics of optical waveguides diffracted field, the theories of mode coupling in optical waveguides and the spectral response theories and simulating method for arrayed waveguide grating. in this paper, a set of beam propagation theory based on eigen modes analysis is set up which afforded theoretical basis for designing and analyzing awg devices. experiment of fabricating sio _ ( 2 ) layer by using porus silicon is also carried out in this paper, which is a new method for fabricating waveguide cladding layer

    本文以設計陣列波導光柵器件為目標，對介質波導光場的本徵波函數，光波導本徵模理論，光波導衍射場特性，光波導模式耦合理論和awg器件的光譜響應特性及模擬方法進行了深入研究，建立了一套基於本徵模式場分析的光波導光束傳輸理論，為波導器件的設計提供正確的理論基礎，並嘗試了利用多孔硅生長厚的二氧化硅，用於製作波導包層材料。
  7. When the beam waist wy of blue - detuned segb along the y direction is 10 mm, and its wx is decreased from 10 mm to 1mm, the absolute diffracted intensity from the segb surface will be 10 times of that from the sgb surface, which can be used to reflect an incident atomic beam with a higher normal velocity

    因此，當橢圓高斯光束的w _ y = 10mm ，而w _ xw從10mn減小到1mm ，半束蘭失諧橢圓高斯光束反射面的衍射光強將比同樣參數條件下的sgb反射面的衍射光強提高了10倍。
  8. However, the intensity gradient ( force ) of the diffracted light of the semi - gaussian beam is far smaller than that of the evanescent - light wave, so its spontaneous emission probability is greater than that from the evanescent - light one when the normal velo city of the incident atom is greater

    然而，因為半束蘭失諧高斯光束衍射光場的強度梯度力遠小於消逝波光場，所以當入射原子速度較大時，原子在半束蘭失諧高斯光束衍射光場中的自發輻射幾率要大於消逝波光場。
  9. Starting from the propagation law of partially coherent light and using a typical partially coherent light, i. e., gaussian schell - model ( gsm ) beam describing the multimode laser in practice, i present in this dissertation the research results on vectorial partially coherent light, spectral changes of partially coherent light passing through optical element, spectral switch of partially coherent light diffracted by an aperture, and the spectral anomaly of diffracted fully spatially coherent light by an aperture

    本文從部分相干光的傳輸理論出發，以模擬實際多模激光的一類典型部分相干光? ?高斯-謝爾模型（ gsm ）光束為主要研究對象，對矢量部分相干光、部分相干光通過光學元件的光譜變化、被光闌衍射的部分空間相干光的光譜開關和被光闌衍射的完全空間相干光的光譜異常等現象進行了深入研究。
