查询词典 visual

In the experiments, detection rate and reaction time were measured to evaluate the visual performance of human eyes at three mesopic light levels0.01, 0.1 and 1 cd·m~(-2 with targets of two visual angles (10 and 2°) at two observing eccentricities (0°, 10°). There generated more than 30,000 single measured data and analysis with statistical and computer methods were done.

本论文的实验选用了探测率和反应时间作为评价人眼在中间视觉状态下视觉功能的主要参数，分别在3组典型的中间视觉亮度作为背景亮度0.01，0.1和1 cd·m~(-2和2组不同视场角的目标(10'和2°)以及2组不同的观测偏心度(0°，10°)条件下，先后在中国和德国进行了30，000多个数据采样，并运用计算机技术进行统计分析和研究。

This research is to find out the effects of light level, visual angle and eccentricity on the spectral sensitivity of human eyes at mesopic region; to validate the possibility of working out the spectral luminous efficacy curves based on visual performance at mesopic light levels; to find the connection between the results of performance-based method and brightness-matching method.

本论文主要研究照明水平、目标大小和目标偏心度等因素对中间视觉状态下视觉功能的光谱响应特性的影响；探讨在视觉功能的基础上获得人眼光谱光视效率的可能性以及基于视觉功能法(Performance-based Method)和传统的视亮度匹配法(Brightness-matching method)之间所存在的联系。

The creative point of this dissertation consists firstly in that monochromatic stimuli instead of combined spectral power distribution were used as visual object, and spectral luminous efficacy curves were drawn from the performance-based method; Comparison between performance-based method and brightness-matching method was then done and therefore connection between these two methods was developed; One more creative point is that the analysis based on the theory of neurophysiology and psychophysics leads to the conclusion that contribution of the colour channel during visual information processing is reflected from performance-based method, which should be considered when CIE develops the new mesopic photometry system.

论文的新颖之处在于实验中使用了单色光谱代替复合谱或物体色作为视觉目标，在分析中间视觉状态下视觉功能的光谱响应特性的基础上反推了人眼的光谱光视效率函数；论文更进一步验证了基于视觉功能法和传统的视亮度匹配法之间的联系，在两种方法之间构造了一座桥梁，为基于视觉功能法的使用初步建立了理论依据；同时论文创新地采用心理物理学的方法进行实验和结合物理学和视神经生理学的知识对实验结果进行分析，从而从视觉信息处理的神经机制层面证明了基于视觉功能法获得的结果包含了视觉颜色通道效应，并对CIE在建立新的中间视觉光度学系统时要充分考虑这一视觉颜色通道的影响提出了建议。

The macular micropathology was the main factor in infecting visual functions after cataract phacoemulsification.

这里提出一种基于神经轴突延迟机制，利用脉冲神经元网络模型对运动目标进行检测与跟踪的算法，该神经网络模型是利用轴突延迟脉冲神经网络模拟人类的视觉特性，从而提取运动目标，并具体分析脉冲神经元网络算法的实际意义。

Methods: The visual P300 mapping were measured in patients with some clinical diseases by Medicid-03E brain evoked potential instrument of Neuronic company, and the visual P300 mapping of patients were compared with that of control group.

使用Neuronic 公司的Medicid-03E脑诱发电位仪分别对临床上的一些疾病患者进行了视觉P300地形图的测定并与对照组作比较。

30 eyes of superficial corneal diseases including corneal dystrophy 12 eyes,scar after infection 7 eyes, dimmer nummular keratitis 6 eyes,scar after trauma 3 eyes and band degeneration 2 eyes were treated with PTK, and examined the uncorrected visual acuity,best corrected visual acuity and refraction respectively at one week,one month,three months and six months after PTK.The analysis of variance and chi-square test were used.

对角膜浅层病变30眼，包括角膜营养不良12眼，感染后角膜瘢痕7眼，钱币状角膜炎6眼，外伤性角膜瘢痕3眼和角膜带状变性2眼行PTK治疗，于术后1周、1、3、6月分别检查裸眼视力、最佳矫正视力和屈光状态等并回顾分析其疗效。

As a real visual system existing in nature, ommateum not only have the same function as other visual systems, but also have its special feature.

复眼作为一个现实中的生物的视觉系统，它首先具有一般生物眼睛的视觉系统功能，在此之外，还拥有其独特的特点。

As a real visual system existing in nature, ommateum not only have the same function as other visual systems, but also have its special feature.

本文就是从这两点展开讨论研究。

The shorter of interruption duration, the more obvious interruption effects, and this support the motion opponency theroy. 3 The different intervals between priming and target were detected. Due to interruption of blank frame, the shorter interruption elicited positive proming effects, which is consistant with integration of temporal and spatial in the human brain. 4 The negative of the same direction is relationship to visual adaption and visual inertia effects.

本系列实验得到以下主要结果与结论：1插入空白图片，将导致特定运动方向的反转，而对二义的运动没有明显影响，反映了空白图片对正常视觉运动的阻断；2阻断时间越短，导致特定运动方向反转的几率越大，即阻断效应越明显，支持运动知觉对立理论；3考察不同间隔的启动——靶刺激，由于空白刺激的插入，启动——靶刺激间隔较短时引起的正性启动效应，与人脑系统对视觉信号的时间与空间整合和视觉惯性是一致的。4同向运动的负性倾斜效应与视觉适应有关。

By the time of its fall, most of the prisoners were writers who had written against the corruptions of the government.
