查询词典 aberrations

In imaging electron optics, for a concentric spherical system composed of two spherical electrodes with electrostatic focusing, the electrostatic potential distribution and the spatial-temporal trajectory of electron motion can be expressed by analytical forms. It is naturally to take such system as an ideal model to investigate the imaging properties, as well as the spatial-temporal aberrations, to analyze its particularity and to find the clue of universalities and regularities.

在成像电子光学中，由两个球面电极组成的静电聚焦同心球系统，由于其静电电位分布和电子运动的空间和时间轨迹能以解析形式表示，很自然被采用作为理想模型，研究其成像特性和空间―时间像差，分析系统的特殊性，从而寻找具有普遍意义和规律性的线索。

In chapter 3, characteristic paraments, focusing structure were discussed, the processing of double cell for phase conjugation was analyzed. Designing criteria of double cell phase conjugation mirror was given out. All phase aberrations could be compensated by using phase conjugation theoretically, but compensation is only effective to phase aberration of uniform polarizing state, it is not effective to aberration by thermally induced depolarization an diffractive effecting by aperture.

在第三章，我们讨论了SBS介质的特性参数，相位共轭镜的聚焦结构，分析了双池相位共轭镜的相互作用过程，给出了相位共轭镜的设计原则；从理论上讲相位共轭技术可以完全补偿热畸变以及因各种光学不均匀性造成的光束畸变，但是相位共轭技术只对偏振态均匀的相位畸变造成的光束畸变起补偿作用，而对由于热致双折射效应造成的退偏以及光束通过硬边光阑时的衍射效应造成的光束畸变无能为力。

When one element of an N-element array is aberrated, the most sensitive aberration is Piston error, and then the sensitive aberrations are element defocus, tilt, spherical aberration, coma and astigmatism. As for four aperture system, the influence of Piston error is 2 times larger than that of defocus, and 4 times larger than that of astigmatism.

在合成孔径成像系统单个子孔径存在像差的情况下，Piston误差对系统的影响最大，其次是离焦误差、倾斜误差、球差、彗差和像散，对于四孔径系统，Piston误差对系统的影响几乎是离焦误差的2倍，像散的4倍。

This intraoperative movement will be important to measure and adjust for as we proceed to address more detailed aberrations with custom ablations in the future.

如果我们在未来要进一步表述个性化手术中像差更多更详尽的东西，这种手术当中发生的运动对于测量和调整将是十分重要的。
