视

Amblyopia was assessed in those children aged 30 through 71 months who were able to perform optotype testing at 3 meters.

弱视是通过评估30至71个月大的能够在3米处进行视标测试的儿童。

When the optotype on the one monitor was cleared away, the optotype on the other monitor was presented at once and lasted a few hundred of milliseconds.

一台显示器上的注视视标消失时，另一台显示器上的视标立刻出现并持续一定时间。

Methods With AT89C51 single-chip as hardware and programmed by C language, the instrument applied, the optometer adopted LCD and international standard optotype. The optotype had 14 lines of object-finders, and only one line of random characters was displayed on the screen every time.

硬件采用AT89C51型单片机，软件采用C语言编程，显示部分采用液晶显示，以国际标准视力表&E&字为视标，视标共14行，每屏显示1行，随机显示字符，视力检查距离为3m，全部程序在单片机控制下完成。

With ERDAS IMAGINE 8.4 software,through rectification,digital orthographical maps inlaying,artificial color composition to Dian Zang railway by generating DEM and compounding with remote sensing image,the paper generates a three dimensional geomorphologic image and visible flight film by extracting information of geological engineering disasters and geological structure.

利用 ERDAS IMAGINE8.4版图像处理软件，对滇藏线原始数据经过校正、数字正射影像镶嵌、假彩色合成图像增强处理后，通过 DEM的获取、生成与遥感图像的配准，制作具有三维视感的地貌影像图及可视化飞行电影动画，提取工程地质灾害、地质构造信息，从工程地质角度对新建铁路滇藏线预可行性做出评价。

As the result of theoretical analysis and practical test, the systematic error corrections of the second-order level measurement must include collimation error correction, refraction error correction and orthometric correction (altitude over more than 50 m in the examining area).

经理论分析与实际测试后发现二等水准测量须做视准轴误差、折射误差与正高改正（测区标高超过50公尺以上），而二等水准测量，则须加人视准轴误差，测区标高超过100公尺以上，亦需加人正高改正。

Methods The 201 cases in 1979～1996 were retrospectively summarized. The clinical features including chief complaints, sex distribution, age at first visit, laterality, type of presentation, ocular deviation in the primary position, refractive errors, amblyopia, globe retraction, change of the palpebral fissure, upshoot and downshoot in adduction, binocular single vision, and its associated ocular and non-ocular anomalies were analyzed.

自1979～1996年回顾性地总结了201例DRS，对它的临床特征，包括主诉、性别分布、初诊年龄、侧向状态、表现类型、原在位的眼位偏斜、屈光不正、弱视、眼球后退、睑裂改变、内转时眼球急速上转和下转、双眼单视及其伴随的眼部和非眼部异常等予以分析。

The patients of group I were diagnosed as AAION and those of group II who had optic edema were acute papillitis,papilloedema and optic vasculitis.

组为确诊急性前部缺血性视神经病变患者，Ⅱ组包括急性视乳头炎、视乳头水肿、视盘血管炎的视盘水肿患者。

The relationships between depth, parallactic polarizability, parallactic resistivity and temperature is non-linear. Taking one point for example the paper studies this question using the BP neural network.

由于深度、视极化率、视电阻率与温度之间复杂的非线性关系，最后本文以某点为研究对象，利用BP神经网络对该问题进行探讨研究。

⑴There are NOS/ER positive neurons in the hypothalamic paraventricular nucleus, supraoptic nucleus, periventricular nucleus and lateral hypothalamic area.⑵The double-labeled neurons were mostly distributed in the medial dorsal and lateral dorsal of supraoptic nucleus and in the medial parvicellular, ventral zone. They were extensive slightly,but scattered in lateral hypothalamic area, sporadic in the periventricular nucleus.

1在大鼠下丘脑视上核、室旁核、下丘脑外侧区及室周核均有NOS与ER双染神经元分布。2 NOS与ER双染神经元主要集中分布在视上核的背内侧和背外侧部及室旁核小细胞部腹内侧区，在下丘脑外侧区分布较广但比较分散，室周核呈散在分布。

The routine contract sensibility function and glare disability value were measured in photopic and twilight conditions with glare.

检测了飞行员常规CSF以及在明视和暮视有眩光条件下的眩光失能值。

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％。
