散光的

Compared with previous reports of similarly aged Singapore Chinese adults, the prevalence of myopia, astigmatism, and anisometropia was lower, whereas the prevalence of hyperopia was similar.

与前期报道的相似年龄的新加坡中国成年人相比，马来人的近视、散光和屈光参差的患病率要低，但远视的患病率相似。

Among 465 children who were regularly followed up for a period of 3 years or more at the clinic, 37 eyes of 23 children showed significant astigmatism changes of 1 diopter or more in amount or 15 degrees or more in axis.

在465位於门诊追踪了3年以上的儿童中，23位儿童的37只眼睛表现1 Diopter以上的度数或15度以上的轴度的散光变化。

So if you're wondering what it was like for Emilie to film with the media frenzy surrounding Robert, or if Brosnan ever experienced the same reaction from his lady fans, now's your chance to ask them for yourself!

因此，如果你想知道Emilie与被散光灯包围的Rob合作的电影是怎样的，或Brosnan 是否也曾有过被女性粉丝疯狂迷恋的经历，现在、是你的机会去找寻他们索取答案！

In this paper, the stray light and ghost image caused by multi-reflection in high power infrared optical systems are analyzed and discussed, and the comprehensive method incorporating paraxial approximation and real ray trace is presented; the data structure of binary tree is used in the storage of interdata so that the storage problem of huge-size data is resolved.

本文主要研究了大功率红外光学系统中光学表面多重反射而形成的杂散光及其数学模型与计算方法，提出了将近轴近似法和有限光线追迹法相结合的综合分析方法；同时在数据存储方式上采用二叉树这种数据结构，巧妙地解决了鬼像分析中海量的中间数据存储的问题。

Excimer laser refractive surgery is an important adjunct to the subspecialty of refractive surgery. The principles of the excimer laser refractive surgery and surgery categories are analyzed.

在初始角膜模型假设的基础上，提出了能够用于近视、远视和散光等屈光手术的数学模型，计算出切削量和切削的层数，并给出了相应的算法框图。

Postoperative manifest refraction was also improved by surgery, showing minimal but significant regression after 1 year. Final BCVA loss was seen in 10 eyes of 7 patients; in 7 cases, there were obvious reasons such as the progression of cataracts in 3 eyes, epithelial disintegrity due to dry eye in 2 eyes, irregular astigmatism due to flap striae in 1 eye, and age-related macular dystrophy in 1 eye.

手术后的显然验光视力也有提高，在1年后表现为极微量却显著的回退。7例患者的10只眼发生了最佳矫正视力的下降，但均有明显原因，如3只眼发生了白内障，2只眼角膜上皮不完整，1只眼由于角膜瓣皱褶导致不规则散光，1只眼为年龄相关性黄斑萎缩。

The emanative ligth shooted by the small bulb which is put at the focus of concave mirror is turn into parallel light by reflecting of concave mirror.

放在凹面镜焦点处的小灯泡发出的发散光经过凹面镜反射变成平行光，这说明在光的反射现象中光路是可逆的。

There are more advantages in holographic grating than in nicking grating such as no optical spectrum,no ghost line,high resolution ratio and so on.

全息光栅与刻痕光栅相比有着更多的优点，如光谱中无鬼线、杂散光少、分辨率高等，因此，全息术成了制作光栅的首选方法，其中光路的选用在制作过程中就尤为重要了，但现有的制作方法选用的光路却不是很恰当，为此，对其进行了改进。

Astigmatism is caused by irregularities in the surface of the cornea or lens and causes the image on the retina to be distorted.

散光所造成的不正常现象的表面角膜或晶状体和原因的形象在视网膜上的扭曲。

The part of the cover that lies over LED bulb irradiation is semicircle curved surface that simulates the glass tube luminous-surface of neon light

一包覆层，由柔性塑料挤出成型一个用于包覆上述芯线、散光体及多个LED灯泡的、与上述芯线等长度的包覆层，该包覆层的位于LED灯泡照射上方的部分是一模拟霓虹灯玻璃管状发光面的半圆形曲面

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％。
