通过透镜

The stakes are so high – and the importance of China to the world so great – that they should not be subject to simplification through a Manichaean lens.

这次赌注如此高昂——而且中国对于世界的重要性如此之大——因此我们不该通过一个摩尼教透镜简单的对其进行分类。

Luhrmann's soft-filtering lens — a man being trampled to death by rampaging cattle or a city being annihilated by bombing Japanese warplanes — the calamities of history are merely colorful grist for his main interest, the romance between a wilted English rose, Lady Sarah Ashley, and an itinerant Australian cattleman, the Drover. The lady and the tramp meet soon after she lands in Australia to track down her cattleman husband, whose early murder sets all the narrative pieces in place. Initially intent on selling her property, including 1,500 head of cattle, Sarah soon transforms into a frontierswoman, seduced by Nullah's smile and the majestic valleys and peaks of both the land and of the Drover's musculature.

Observe an object far away through the lens, it will appear upside down; on the other hand, observe an object nearby-it will be enlarged.

通过菲涅尔透镜观察远处的物体，则物体的像是倒立的，而观察近处的物体时会产生放大效果。

The third chapter of the thesis discusses a novel paraboloidal lensed multimode fiber used in the fiber coupling of the high power single emitter broad area diode laser, and the results of the computer aided simulation of the coupling have been described too, the results verified the theory of paraboloidal lensed multimode fiber.

第三章详细讨论了利用抛物面型微透镜多模光纤与大功率宽发射域半导体激光器的耦合效率；利用计算机辅助模拟了耦合过程，并通过实验验证了耦合系统的可行性。

A tube containing a convex achromatic lens at one end and a slit at the other with the slit at the focus of the lens; light rays leave the slit as a parallel beam.

一端包含一个凸起的消色差透镜另一端在镜头的中心有一个小切口的小管；光线通过小切口成为平行光线。

Focusing properties of elegant cosh square Gaussian and Sinh square Gaussian beams through a thin lens are studied in detail. And intensity distribution on the axis and focusing intensity distribution are analyzed. Also focal shift of Sinh square Gaussian beams are studied.

详细研究了复宗量双曲余弦平方-高斯光束和双曲正弦平方-高斯光束通过薄透镜时的聚焦特性，分析了光束的轴上光强分布和聚焦场的光强分布，讨论了双曲正弦平方-高斯光束的焦移。

种子以及种皮的很明显地膨胀损坏可以通过手持透镜观测到。

BSpatial characterization of laser induced Cu plasma in air with different laser focusing distancesThe plasma spectra induced by pulsed laser ablation of copper target are measured. By adjusting the distance of the len-sample, the spectrum of air spark plasma、 Cu plasma and the reciprocity of both plasmas are analysed. From the result, it has been shown that the focusing of the laser beam has an important infunence to analyse the properties of the sample.

b 不同的激光焦点位置产生的等离子体光谱的空间特性研究激光烧蚀置于空气中的Cu靶产生等离子体，通过调节透镜与Cu靶的距离，本文观测了激光烧蚀空气产生的空气火花等离子体、激光直接烧蚀铜靶产生Cu等离子体以及空气火花等离子体与Cu等离子体相互作用等不同情况下的激光诱导击穿发射光谱，激光束焦点的位置在分析材料性质的过程中有着重要的影响。

The Focusing property of flat-topped multi-Gaussian laser beam by lens with spherical aberration is discussed.

利用广义惠更斯-菲涅耳衍射积分公式，研究了平顶多高斯光束通过球差透镜的聚焦特性。

The system can be calibrated by adjusting the position of at least one lens to focus unpolarized light onto the PBS array, thereby reducing reflection of the unpolarized light from the polarizing beam splitter array.

该系统可以通过设置至少一个透镜的位置调整，从而将非偏振光聚焦在偏振光束分束器阵列上，由此减少反射。
