Based on the Sasians aberration theory of a bilateral symmetric optical system, the image quality of a rear view mirror with a spherical surface is studied comprehensively.

The off-axis reflection system composed of four aspheric mirrors was designed, but the system structure was not so simple and the performance can also be improved, besides, manufacture and test for large aspheric mirrors are difficult; and then the spherical Fresnel mirror which is easier to be manufactured and tested was used to replace the aspheric mirror, the spherical Fresnel mirror has low cost of replication, but this design also can\'t be used in projection lens because it was only feasible in narrow wavebands; Furthermore, the design making use of catadioptric projection lens was accomplished, this design is greatly applied in rear projector because it has merits of both refraction and reflection. But it had difficulties in color aberration correction and had complex structure.

设计了四片非球面组成的离轴式反射系统，然而，仅采用非球面设计系统结构不够精简，性能也有待进一步提高，且非球面面形较大时加工和检测都存在一定的困难；继而提出了用球面Fresnel反射镜代替非球面的设计方法，虽然Fresnel反射镜加工和检测更为简单，且复制成本低，但对波长具有选择性；进而，应用折反系统结合的方式设计了离轴式投影镜头，该方法因兼具折射和反射的优点，在大屏幕超薄背投系统的设计中广为应用，缺点是会产生难以校正的色差，且结构复杂。

Thes are the magnification factor, the spherical aberration and the space charge effect.

本文从分析9显象管电子枪的结构特点出发，讨论了影响荧光屏上电子束光点尺寸的三个主要因素：透镜放大率、球面象差和空间电荷效应。

Based on the eye model proposed by Hwey-Lan Liou,the impact of intraocular lens with different spherical aberration over same optical zone decentration and tilt on performance of human eye was analysised with ray-tracing method using ZEMAX software.

Varying slight ly from sphericity and having only slight aberration,as a lens.

非球面的与球状体略微不同，只有很小偏离，如镜片

He's a spinoff -- and it's not even right to say that he was a spinoff of the Mormons, because people like the Smarts are Mormons, and this guy is an absolute aberration.

他是一个支派甚至乎说他是摩门教的支派都是不对的，因为像Smart一家也是摩门教徒，而这家伙绝对是精神失常的。

Stalinism was not an aberration, he argued, but the inevitable consequence of pursuing a communist utopia.

在他笔下，斯大林主义并非怪胎，而是对共产主义乌托邦的追求所必然导致的结果。

Based on the aberration theory of AWG, a new-type flat-field AWG is designed. The focal signals of all wavelengths of operation are focusing along a straight line perpendicular to the propagation direction. Three stigmatic points restrain three dominant geometry parameters. Furthermore, a new-type flat-field wavelength router with both flat input field and flat focal field is also designed.

基于阵列波导光栅的像差理论，利用三个无像差点约束三个主要结构参量，设计了新型平场聚焦阵列波导光栅，使得所有工作波长的输出信号都聚焦在与光束传输方向垂直的直线上，并进一步将其拓展为同时具有平输入场和平聚焦场的新型平场波长路由器。

When EMS was applied, it was found that 2.0% EMS resulted the highest microkernel rate (15.6‰). Treating the materials with 2.0% EMS for 4 hours could lead to semi-lethal. Cytological observations found that chromosome aberration phenomena such as single microkernel, double microkernel, three microkernel, chromosome bridge, resort chromosome and syncytium were presented in the mutants.

EMS诱变途径中，浓度为2.0 %处理时间为4 h的组合获得最高的微核率（15.6‰），EMS浓度为2.0 %处理时间为4 h的组合使材料达到半致死；细胞学的观察看到了单微核、双微核、三微核、染色体桥、滞留染色体和合胞体等染色体畸变现象，再生苗中发现了1棵变异株。60Co辐射的诱变途径中，20Gy的剂量使不定芽半致死，再生苗中发现了1棵变异株。

The influence of aberration on measuring sensitivity in critical-angle method of total reflection for focus error detection was described.

摘要分析了在临界角方法探焦技术中像差对测量灵敏度的影响。

Alternatively, the con- trollers can use the synchronous rectifier itself or loss- less inductor current-sensing methods to provide overload protection with lower power dissipation.

另外，康威特罗勒斯可以使用同步整流器本身或亏损减少电感电流检测方法，以提供低功耗过载保护。
