annular beam meaning in English
环形电子束
环状电子束
Examples
- The focusing properties of an annular beam are demonstrated , which give guidance for some design in icf driver structure . 4
给出了环形光束聚焦特性分析，对于icf中“同轴型”双程放大光路布局设计检验有着理论上的指导意义； 4 - A practical soft - edge annular beam is also studied numerically and the similar properties are obtained t6 confirm our analysis
然后利用数值模拟的手段，研究了带软化因子的环形光束的聚焦性质，从而在整体上给出了环形光束的聚焦性质。 - In chapter 3 , by using theoretic analysis the focusing properties of an ideal annular beam is demonstrated . the intensity distribution near the focal point is given explicitly to show the influence of the ratio of inner to outer radius
第三章，从理想的环形光束出发，先在理论上分析了环形聚焦光束在焦点附近的光强分布情况和光束内外径之比(占空比)对聚焦性质的影响。 - The paper presented a large annular cantilever beam string stadium roof structure using the theory of beam string structure . the stadium roof structure is a novel structure that is reasonable in bearing force by using the character of the tendon and beam fully . the struts in the structure avoided enduring big moment , moreover the pre - stress upper chord tendon and the annular beam work together to resist upward and downward load , as embody the structure ' s artifice and wonderful space mechanical property
本文利用张弦梁原理，给出了一种大型环状悬臂型张弦梁挑蓬结构，该种体育场挑蓬结构新颖，充分利用了拉索和立体桁架受力的特点，使得结构受力更加合理，避免了柱子承受较大的弯矩，上弦索的预张力和圈梁使结构共同作用抵抗上下荷载，更体现了结构的巧妙和良好的空间受力性能。 - For this purpose , by combining techniques of optical superresolution and image superresolution , this thesis proposes a novel lateral superresolution confocal microscopy method based on image restoration and annular pupil filtering . the following two aspects are the main research work i have completed so far . first , designed and realized a shaped annular beam confocal microscopy system ( sabcms ) , in order to improve the lateral resolution of cm
第二,对整形环形光共焦显微系统所成像进行基于最大似然估计法( maximumlikelihoodestimate , mle )的超分辨复原处理,以期进一步改善共焦显微镜的横向分辨力,具体包括: 1 .实现基于pmle ( mlebasedonpoissondistribution )法的图像复原式整形环形光横向超分辨共焦显微成像系统。
