1.As a principal part for natural space, human are the fundamental parts in spatial visibility analysis. The paper first discusses the human visual physical enginery, and furthermore analyzes conception and cognition in visibility analysis, as they are the root of the way that we conceive the geo-space.
空间可视分析和认知是分不开的,作为自然界主体的人是空间可视分析的基础,论文首先探讨人的视觉生理机能,进而分析视觉可视分析中的感知和认知,这是我们认识地理空间的根源。
2.The correlation coefficient of the BC with the visibility was more than the ones of the PM10 and PM2.5. So the fine particles had more marked influence on the decrease of the visibility than coarse particles.
PM_(10)、PM_(2.5)和黑碳浓度与能见度均呈负相关,细颗粒物是影响能见度的主要因素。
3.VISIBILITY: The visibility of grains added.
微粒可见程度。
4.IT managers will need greater visibility into their enterprise networks to pinpoint potential problems before they effect performance and hamper e-business.Probes provide that necessary visibility.
将来，IT经理们需要更清楚地看见其企业网络，在潜在问题影响性能、妨碍电子商务之前诊断出这些问题，探头提供了这种必要的可视性。
5.The paper first discusses the concepts of visibility centricity, and quantifies the parameters of visibility analysis on viewpoints to explore urban morphology of street network with pedestrian movement.
在视域的行为指导原理上，采用可视集中性的概念来进行可视分析，进而通过可视分析各参数的具体量化，包括视域面积、视线长度等，将其应用到具体的城市街道形态中，分析各参数量化大小的分布情况。
6.Vertical visibility 50m in fog, sky obscured.
垂直能见度50米，有雾，天空不明。
7.Determines the visibility state of the given window.
这个函数确定给定窗口的视觉状态。
8.A extreme climatic calamity, terrible deterioration of visibility and air quality over PRD, occurred from the end of Oct. to the beginning of Nov.2003.
2003年10月底至11月初，珠江三角洲出现了一次空气质量和能见度均十分恶劣的灾害性极端气候事件。
9.Wavelets are becoming a key technique in the ongoing source compression standard JPEG-2000.The positive arguments for advocating DWT in image watermarking are: preventing watermark removal by JPEG-2000 lossy compression, reusing previous studies on source coding regarding the visibility of image degradations, and offering the possibility of embedding in the compressed domain.
在小波域嵌入水印的原因是：可以防止由于JPEG-2000有损压缩而造成的水印消除； 可以利用信源编码领域对图像失真的可见性研究成果控制水印的嵌入位置和强度；
10.Based on twenty-five stations of Crustal Moment Observation Network of China, satellite visibility and positioning creditability based on GPS, GALILEO and integrated GPS-GALILEO are analyzed deeply.
并结合GPS系统,以中国地壳运动观测网的25个基准站为地面观测站,对大陆范围内基于GPS、GALILEO以及GALILEO-GPS组合系统进行单点定位时的卫星可见性和给定精度下的定位可信度进行了系统的分析。
