With normal vision were studied. The result showed: 504 eyes (77. 54%) suffered from hyperopia, 66 (10.15%) from myopia, 2(0.31%)from astigmatism and 78(12. 00%) were emmetropia. Among 325 youths, 172 (52.92%) had esophoria (including esophoria-hy- perphoria), 126 (38.7%)exophoria (including exophoria-hyperphoria), 13(4.00%) hyperphoria and 14(4.31%)had orthophoria. No significant...

结果显示，远视者为504眼(77.54％)，近视者66眼(10.15％)，混合散光者2眼(0.31％)，正视者78眼(12.00％)，325人中，内隐斜者为126人(38.77％)，上隐斜者13人(4.00％)，正位者14名人(4.31％)；经用行x列表的x~2检验法分析，屈光不正的类型与斜视的种类之间没有显著联系。

A R-C system with foci of 2 m and f-number F/4 was taken for an example, the principles of stray light eliminating and evalutiong in reflective optical system was put forward. Lens hood in the main mirror, lens hood outside and window shade, lens hood in the secondly mirror were designed by CAD modeling.

以焦距为2 m，相对孔径为1/4的R-C系统为例，介绍了利用计算机仿真技术进行消杂散光设计和评价的原理，结合CAD建模进行了主镜内遮光罩、外遮光筒、次镜百叶窗式遮光罩的设计。

Taking stray light in "Shenguang III" as the study subject and basing on the basic principle of geometrical optics,Applying the technological path of paraxial ray and real ray tracing,a new analytic way and data structure,which suits for the specific requirement in analysis and process of ghost images,is presented.

本课题就是以"神光-Ⅲ"激光装置中的杂散光为研究对象，针对高功率多程放大系统在鬼像分析与处理方面特殊要求，从光线光学的基本原理出发，应用近轴光线与空间光线追迹技术路线，提出一种新型的分析方法和数据结构。

For testing zoom lens stray light, it is necessary to understand the role of every test component and their impact on the measurement results.

在对变焦距光学镜头进行杂散光系数测试的过程中，需要了解各测试环节的作用及对测量结果的影响。

SIA degree in phacoemulsification with 3.2mm clear corneal incision has no connection with incision positions. Corneal curvature at incision meridian will be released, but another meridian has no distinct effect. The SIA analyzed by Jaffe/Clayman vector method will provide an important reference for toric IOL implantation surgery.

3.2mm透明角膜切口SIA的度数与切口位置无明显关系，切口对所在子午线角膜曲率有松解作用，对与切口垂直子午线角膜曲率无明显影响，矢量公式法计算所得的SIA值在散光型人工晶状体植入术中提供了重要的参考价值。

It is found that the bright points distributed regularly adjacent to main facular is spectral distribution on the focal plane of the array of lens when the laser irradiates a hexagonal aperture,rather than what is induced by stray light.

结果表明，主光斑附近规则分布的亮点并不是由杂散光引起的，而是激光辐照六边形光阑，在透镜组焦平面所成的频谱分布。

Major causes of limited visual acuity were irregular astigmatism resulting from central or paracentral corneal scar or developing macular pucker.

术后视力的改善受限于因角膜中央或旁中央疤痕所致的不规则散光及发展的黄斑皱褶。

The C31 and C33 of the myopia subjects with moderate astigmatism show statistically significant changes after being fitted with both sphere and moderate cylinder trial lenses.

单纯近视者矫正离焦后引起C40的明显变化；近视中度散光者完全矫正屈光不正后呈现C31和C33的显著变化。

Compound lens or lens system designed to be free of astigmatism and able to form approximately point images.

没有散光并且能够形成近似的图像的透镜或透镜系统。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
