The basic information consists of luminance information and chrominance difference signals. During the composition into one signal, the chrominance signals can interfere with the luminance. Therefore, the television technique has to adopt appropriate modulation methods to eliminate the interference between luminance and chrominance signals.

基本信息由亮度信息色差信号组成，由于在合成中，色度信号可能会干扰亮度信号，因此，还要采用适当方法消除色度信号和亮度信号之间的干扰。

In this dissertation, we optimized the thinkness of each layer of TFEL devices using the layered optimization method to obtain ZnS: Ce〓 TFEL devices. Accoding to the energy level structure of Ce〓, two criteria for distinguishing the EL of Ce〓 were found out, from which it was conduded that the TFEL of ZnS: Ce〓 comes from 5d→4f transition of Ce〓. The measurement of brightness waveform showed that the TFEL of ZnS: Ce〓 was the luminescence from independent centers. and there were the field induced-delocalization in this process anf it〓s the cause of low TFEL efficiency of ZnS: Ce〓. In this dissertation, different influence factors on TFEL of ZnS: Ce〓 were sdudied. The influence of different host lattice is different: The blue/green ratio of ZnS: Ce〓 in hexagonal system of ZnS is larger than that in cubic system of ZnS, and the TFEL peaks in hexagonal system of ZnS moves toward longer wavelength compared with that in cubic system of ZnS. The adding buffer layer was used in this stage. The solubility of Ce〓 in ZnS was small and it was another limit to TFEL brightness of ZnS: Ce〓 device. The solubility of Ce〓 increased ten times when using Li ions as flux, so that the TFEL brightness of ZnS: Ce〓 was enhanced. It was found that the appearing of ZnO in active layer improves the TFEL of ZnS: Ce〓: the brightness and the wave range of ZnS: Ce〓TFEL were enhanced.

本文采用TFEL的分层优化方案，优化组合了各膜层厚度，选择最佳制备条件，得到了ZnS：Ce〓的TFEL；根据Ce〓的能级结构，找到了判别Ce〓的EL的两个简单依据，并据此断定ZnS：Ce〓的TFEL的两个发射峰分别属于Ce〓的〓和〓跃迁；亮度波形测量表明ZnS：Ce〓的TFEL属于分立中心发光，分析认为在此过程中存在着较严重的场致离化，这也是ZnS：Ce〓的TFEL效率较低的一个原因；本文考查了影响ZnS：Ce〓的TFEL的各种因素，发现：基质的晶体结构对ZnS：Ce〓的TFEL有所影响，在六角相ZnS中Ce〓的TFEL优于立方相ZnS中Ce〓的TFEL：发射峰的蓝-绿比相对较大，且光谱向短波方向移动，在此项研究中本文采用了在发光层前增镀过渡层的办法，过渡层为六角晶相的ZnO；限制ZnS：Ce〓的TFEL器件亮度的一个原因是Ce〓在ZnS中的溶解度低，本文用Li离子作助溶剂增大了Ce〓的溶解度，增大幅度为一个量级，并且ZnS：Ce〓的TFEL亮度明显提高；从ZnS：Ce〓的TFEL光谱来看ZnS：Ce〓的TFEL波长覆盖范围较小，亮度也不高，达不到做为白色TFEL材料的要求，需要寻找新的白色TFEL材料；在研究ZnS：Ce〓的TFEL中还发现：发光层中ZnO的出现有利于ZnS：Ce〓的TFEL：发射峰变宽、亮度增大。

For illusory border induction in the abutting grating illusion it is 5. 3%.(3) Random-dot stereograms are found to induce depth equally well in both display modes. The disparity threshold for perceiving depth in isochromatic random-dot stereograms levels off at a luminance contrast of 30%.

在亮度对比与等亮度颜色对比的条件下，受试者的立体视敏度不存在有统计学意义的差异；并且，当双眼接受不同颜色对比的等亮度立体图对刺激时，与亮度对比条件相比，受试者的立体视敏度也无明显差异。

After the review of the previous studies on the models of sky luminance distribution, it is the first that this thesis make the systematic study of the pseud-overcast sky luminance distribution by two characteristics of the maximum sky luminanace element and the luminance lapse rate with that the all of sky luminance distribution is determined. Through discussed, these methods and results on pseud-overcast sky study are suggested to be valid of the standardization of intermediate skies in this thesis.

在较为系统地分析了前人有关天空亮度分布模型的基础上，首次利用天空最大亮度元和亮度变化率二个确定天空亮度分布的特征量，对构成中间天空（除CIE全阴天空和CIE全晴天空以外的一切真实天空）之必要部分的似阴天空进行了系统的研究，从而为中间天空的标准化提供了有意义的方法和结果。

所谓亮度不均匀性就是显示器最低亮度的点与最高亮度的点的亮度比值。

Multiple linear regression equation between LST and brightness temperatures of AVHRR channels 4 and 5 was almost at the significant level (p＜0.05), and the level was not improved by adding brightness temperature of AVHRR channel 3 as a regressor. Path analysis is a statistical technique that partitions correlations into direct and indirect effects, and differentiates between correlation and causation. The results of path analysis showed that the direct effects and indirect effects of brightness temperatures of AVHRR channels 4 and 5 to LST were strong, respectively, the direct effect and indirect effects of brightness temperature of AVHRR channels 3 to LST were weak. These implied the brightness temperatures AVHRR channels 4 and 5 should be involved in retrieving LST.

多元线性回归分析结果表明，土地表面温度与AVHRR第4、5波段亮度温度间的回归方程接近5％的显著水平；通径分析的结果表明，AVHRR第4、5波段的亮度温度对土地表面温度的直接作用和间接作用均较强，而AVHRR第3波段的亮度温度对土地表面温度的直接作用和间接作用均较弱，因此，在反演土地表面温度时必须同时考虑AVHRR第4、5波段的亮度温度。

The results indicate the effect of light level, visual angle and eccentricity on detection rate and reaction time at mesopic region; shows series of spectral luminous efficacy drawn out from the experimental results since monochromatic stimulus was used; proves that the results from performance-based method are in essence compatible with those from bright-matching method, since both of them are in accordance

本论文实验和计算结果确定了背景亮度、视场角和偏心度对人眼探测率和反应时间的影响程度；根据视觉功能的基础和实验中选用单色光谱作为视觉目标所得到的数据推导出人眼在中间视觉状态下的系列的光谱光视效率函数；本文研究结果证实了基于视觉功能法和视亮度匹配法所获得的光谱光视效率函数在本质上的一致性，它们都能反映出随着亮度降低而产生的浦尔金耶偏移效应(Purkinje-shift)，但本论文所采用的基于视觉功能法还能反映出人眼视觉信息处理中的颜色通道效应。

Luminance 亮度 A measure of the brightness or luminous intensity of light, usually expressed in units of Candelas per square meter (cd/m2) or foot Lamberts.

有点亮度或者发光的强度在光中，通常在坎德拉每平方的单位表示米(cd/m 2)或者脚蓝伯特。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
