And the object space aperture angle is the dominant factor that makes the distribution of Poynting vector lose circular symmetry.

并且物方孔径角是导致玻印亭矢量分布失去圆对称性的主要因素。

This feature gives a reasonable explanation for the mechanism of CAS. The phase velocity of diffraction fields for uniform plane wave on a circular aperture has been investigated. It is shown that diffraction can result in subluminous phase velocity at certain points of optical field in vacuum.

如果相对论电子能够注入到这一通道内，那么它与激光场间的相移就可能变得非常小，从而能够长时间地保持在加速相中得到极高能量。

Using plane wave circular aperture diffraction as an example, this researchstudied the changes ofηwith diameter of diffraction holeρ_0, propagation distance zand light spot radius r and found how to obtain the largest energy concentration degree by controlling these three factors.

本课题以平面波圆孔衍射为例，研究了光束能量集中度随衍射孔径ρ_0、传播距离z和光斑半径r的变化规律，并指出如何控制这三个因素来获得光束的最大能量集中度。

Just like the artful loft conversions that overlook the trendier parts of Manhattan or Clerkenwell, the Clubman is adorned with aperture art that's as much about look-at-me drama as ease of use.

光圈艺术在Clubman上的运用带来安逸舒适的体验，如同透过可以远眺曼哈顿或克拉肯威尔繁华街区的顶楼窗口，巧妙绝伦！

The resolution is discussed as a function of two parameters, the spatial coherence condition of illumination and the central obstruction of an annular aperture.

将两点之分辨作为两个参数的函数进行了讨论——其一为照明光的空间相干条件，其二为环型孔的中心阻挡。

The acoustic analysis results of axial configurative tongue design with aperture or comb shaped can reduce the BPF peak effects. Therefore we can not only receive better sound quality on the experiments, but also get a similar effect in fluent 6.2 simulations.

结果在声场分析方面，应用孔穴或梳状轴向舌端构形确有降低叶片通过频率声压峰值之效果，因此可获得较佳的音质优化程度，同时在fluent 6.2 中所模拟得到与穿孔型舌端有相近的结果趋势，且其出风口质量流率高转速时明显优於标准舌端
