查询词典 Lens

Crystallins are the major structural protein of the lens. Mutation in the crystallin genes can result in lens opacity.

晶状体蛋白是品状体中最主要的成分，其编码基因的突变与先天性白内障的发生密切相关。

The fringes region varies in measuring the lens focal length using Moire deflectometer, when different measured lens and others optical parameters are used.

当用莫尔偏折法测量透镜焦距时，条纹区域随着被测透镜和系统光学参数的不同而变化。

Triangle lens is best in uniformity, and hexangular lens has better light collecting efficiency.

利用三角形积分透镜可以获得最佳的照明均匀性，但光能利用率相对较低，六角形积分透镜可同时获得较高的照明均匀性和光能利用率。

Central fenestrations did not affect the clinical outcomes, indicating that corneal compression by the lens in the para-central region as opposed to central post lens tear film suction may be the primary mechanism behind the hyperopic OK clinical effect.

中央开窗术并不影响临床结果，表明镜片对角膜旁中央区域的压缩，而非中央区镜片泪膜的抽吸可能是远视OK临床疗效的主要机制。

After relations between growth speed of final ice lens and segregation temperature were analyzed, the decrease of water intake speed at high segregation temperature was pointed. For small heave induced by intermissive freezing mode of controlling frost-depth, the mechanism of using intermissive phase to increase segregation temperature of the final ice lens so as to restrain its growth was proposed.

进一步定量考察末透镜体的生长速度与分凝温度之间的关系后，指出较高的分凝温度将会导致吸水速率的降低，而控制冻深的间歇冻结模式其机理就是利用间歇阶段促使末透镜体的分凝温度升高，抑制末透镜体的生长，进而达到减小冻胀的目的。

The mature stage continued for over long time, generally for several years,the water in the lens lost continuously, the volume of lens diminished, the capsular membrane shrank, the anterior chamber deepened with iridodonesis.

过熟期：如果成熟期持续时间过长，经数年后晶体内水分继续丢失，体积缩小，囊膜皱缩，出现不规则的白色斑点及胆固醇结晶，前房加深，虹膜震颤。

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 split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
