Methods The photopic ERG of three kinds of macular diseases were recorded, the amplitudes and latency of photopic white b-waves where analysed.

方法对三种黄斑病变进行双眼明视视网膜电图的检测，以明视白光b波的振幅及潜伏期作为观察指标。

In 0. 1 mmol/L Ca2+,glutamate-isolated P 1Q components,both photopic and scotopic,are enhanced,suggesting that the differential effects of low calcium on the horizontal cells must occur during signal transferring from photoreceptors to horizontal cells.

在0。 1 mmol/L Cal+ Ringer液灌流时，无论是明视PI或暗视PI，其反应的幅度均增大，提示发生在低钙时Cone-HC和Rod-HC光反应性的不同变化产生于突触传递的过程中。

Pupil location under scotopic , photopic and pharmacologically dilated conditions

明视，暗视及药物散瞳状态下的瞳孔位置

The descending rates were 19.4% and 21.4%, respectively, which showed significant differences (P.01). While in the photopic environment, the average dynamic visual acuities under the conditon of acute mild hypoxia didn't show significant differences, compared with those under the normal condition.

结果：在暮视光环境条件中，2种（30、45 km/h）纵向动态视力的平均值急性轻度缺氧状态下比正常状态下有明显下降（P.01），下降率分别为19.4%和21.4%；在明视光环境条件中，纵向动态视力的平均值急性轻度缺氧状态下与正常状态下相比无显著变化。

Methods The operation was performed through a posteromedian skin incision with the aid of an endoscope coupled with a television and video unit.

将内视镜置于脊柱后正中切口内，在内视镜放大影像和直视相结合下操作。

GnRH somata were found in the dorsal midbrain, preoptic area and the periventricular rostral midbrain.

GnRH神经细胞本体主要分布在前脑、视前区、下视丘及中脑后部靠近脑室的位置。

firstly, this paper discussed the feasibility of the application of gis technology and multimedia technology in campus' unexpected public incident managing system from the view of system design, and proposed the overall design of emergency preplan managing system of campus.

从系统设计的角度，分析了地理信息系统技术、多媒体技术在校园紧急预案可视化系统中应用的可行性，提出了校园可视化应急预案体系管理系统整体设计方案。

At present, the soundness rate of presbyopic glasses on the market is continuously somewhat low, few factories can truly achieve pupil distance ,pupil height conforms to the national standard and the developed national standard ,the company achieves " strict examination, conforms to the standard ".

目前，老视镜产品的市场合格率一直偏低，能真正做到瞳距、瞳高等符合国家标准的及发达国家的国家标准的厂家寥寥无几，公司保证出厂的任何一副老视镜做到&严格检验，符合标准&。

The company independently develops advanced presbyopic glasses,equipped with high-quality operator, guarantees all presbyopic glasses sheared accurately, pupil distance standard, vertical mutually misses, the horizontal mutually difference conforms to the national authoritative organization examination standard.

公司自行研制设计先进的老视镜生产设备，配备高素质的操作人员，保证所生产的老视镜割片准确，瞳距标准，垂直互差、水平互差符合国家权威机构检测标准。

Results the nipple surface blood was from central retinal artery,sieve plate former district,sieve plate district and postzone were from short posterior ciliary arteries.sieve plate postzone caliber was the thickest,the surface was the next,sieve plate prezone and sieve plate district were the smallest.conclusion the difference of blood capillary caliber in nipple prompts ischemic lesions occur easily in sieve plate prezone and sieve plate district.

结果 视乳头的血供除表层来自视网膜中央动脉外，其余筛板前区、筛板区和筛板后区主要来自睫状后短动脉。筛板后区口径最粗（7.3±1.4）μm，表层次之（6.2±1.3）μm，筛板前区及筛板区最细（4.9±0.7）μm，（5.0±0.8）μm。结论视乳头各层毛细血管口径不同，提示筛板前区及筛板区容易发生缺血性病变。
