查询词典 lens

Keratometer was used to check the corneal curve at 2 direction for 3 times to offer the mean K value, and a nearest basal lens to K value was selected as the trial lens.

步骤一：用角膜曲率仪测量角膜曲率，两个方向各测三次，取平均值，得到角膜曲率的平均K值，选取与K值接近的镜片作为试戴片。

The ocular accommodation has a great influence on refractive components. It is not only the process by which the refractive power of the lens is increased. But the lens itself moved forward relatively. The accumulation effects of accommodation induced by near-work is the main cause of myopia developed in children. The asymmetry of corneal surface was not only related to keratometer K1 and K2 , even the curvature within the same horizontal or vertical meridian was asymmetry.

调节本身不仅是传统意义上的睫状肌收缩和晶状体变凸，同时还伴有晶状体的相对前移；调节对眼的几乎所有屈光构成因素有着显著的影响，视近活动的累积效应是儿童近视眼发生的主要原因；角膜的非球面性不但表现为两个相互垂直子午线的曲率不等，即便是在同一垂直或水平径线上的屈光分布也是非对称的。

Objective: To determine a accurate method to measure ocular axial length,anterior chamber depth lens thickness and keratometry by calculating degrees of intraocular lens demand.

目的：通过对人眼球轴长、前房深度、晶体厚度和角膜曲率的测定，探讨它们之间的相关性，并把握如何精确测定眼球轴长、角膜曲率来保证人工晶体的正确计算。

Second, we put lens in front of the right eye of the subjects, the degree of lens were increased laddered by 0.50D (range+1. 00～+4. 00D,-1. 00～-4. 00D), induced simply myopia and hyperopia anisometropia.

第二阶段用插片法在受试者右眼前放置正负球镜，以0.50D为梯度逐级增大，范围+1.00D～+4.00D、-1.00D～-4.00D，分别诱导单纯近视和远视性屈光参差。

The mostly used techniques to improve the coupling efficiency and alignment tolerance include using micro single lens, micro lens group and lensed fiber.

通常采用单个透镜，透镜组或者光纤微透镜的方式来改善半导体激光器的出射光束质量，提高耦合效率和容忍度。

凹面透镜，凹透镜，近视镜片

And more recently, it has been working in monocularly camera system have developed out of the interchangeable lens type digital camera, a journalist or professional photographer, because the old cameras equipped with and it is compatible with the camera, but in monocularly motorsied and rich control in place, and to use this old advanced in monocularly camera, the only disadvantage is that there is still a lens multiplication problem, to the wide angle shooting embitterthe, but improvement of aircraft and will soon be listed but by large camera with digital back systems are commercial photography only because the file is large, and you can control the level of the grass, and so on up-dip perspective, but price and a gateway to nearly one million, and the economy.

而最不远由老牌不复眼相机编制所成长不入的可互换镜头式数字相机，是故事记者或副业影相师的最爱，因为旧有镜头等配备和其编制兼容，而不复眼相机的机动性与丰裕的操控功用包罗万象，和搁置原有矮档不复眼相机实在一模差别，独一弊端是仍有镜头倍率的题目，给广角拍摄时甚为悲苦，但保守机种很快不离会上市！而由不小型相机配上数字机不面的编制是贸易影相的钝器，因为其档案较不小，又可把持仰俯等透视角度，但代价不远百不一，经济门坎较矮。

The lens also has a second lens group moveably positioned along the optical axis.

该透镜还具有沿光轴可移动放置的第二透镜组。

5In the foundation of staring ommateum system,we full use the ultra great angle ofview of the fish-eye lens,and proposed the most effective staring detection system thatbased on the fish-eye lens further more.

5在凝视复眼型光辐射成像探测系统的基础上，充分利用鱼眼镜头超大视场角的优点，进一步提出了凝视型鱼眼核爆炸光辐射成像探测系统。

In the generalization of contact lens develops day by day, on the issue associated with corneal infection due to incorrect habit of contact lens is put much emphasis. Pseudomonas aeruginosa is one of the most important infectious pathogens, it will adhere on the cornea and destroy the corneal tissue opportunistically with its quite violent virulence. The infected corneas will be attacked to necrosis by one to two days with very fast destructive speed. It is very important to diagnosis the infectious pathogen in time.

在隐形眼镜愈来愈普及的趋势下，因隐形眼镜配戴习惯不正确造成角膜感染的议题也逐渐受到重视，而绿脓杆菌正是其中最重要的一种感染病菌，其会附著在角膜上，然后伺机地破坏角膜组织，绿脓杆菌毒性相当猛烈，故其破坏的效率相当地快，角膜大概一至二天就会被摧残溃烂，因此即时诊断出角膜感染的病原体是相当重要的。

The witness also told the jury at the Royal Courts of Justice in London that he saw a paparazzo fighting with a member of the public who was trying to stop him taking pictures in the minutes before the emergency services arrived.

他还告诉在伦敦皇家法庭的陪审团，在急救服务到来之前，他当时看见一个狗仔队正和一群阻止他拍照的人打架。
