  1. Jiuzhaigou is noted for its freshet air in the world, with an atmospheric visibility of 50 kilometers. situated in a temperate zone

    「貴公司作為世界著名的汽車廠商，希望我們今後能有更多更廣闊的合作！ 」
  2. Visibility distance, a term commonly used in meteorology for assessing atmospheric performance, is a major parameter in analysis and design of opto - electronic imaging system

    氣象學的能見距離是在光電成像系統分析和設計中常用的大氣性能評價參量。
  3. In the first part, the basic knowledge of particle scattering in meteorology and physics was introduced. the particles to be discussed include aerosol particles, fog droplets and raindrops and the em wave band in the discussion is near - infrared. in the second part, the mie theory was briefly reviewed and was applied to investigate the scattering characteristics of spherical atmospheric particles, the result shows that in the visibility measurement meter using forward - scattering method, when the working wavelegth is between 0. 8 m ~ 2 m, the scattering angle is between 25 ~ 40, the distinguishability and the relative scattering intensity would be better than those under other conditions. in the third part, the superellipsoid was used to describe a wide range of shapes such as spheres. ellipsoids and cylinders. an improved t - matrix method which can be used to calculate arbitry shaped particle ' s scattering field was introduced, and the scattering characteristics of non - spherical atmospheric particles was investigated with this method

    計算結果表明，從相對散射強度、同一方向上不同粒子散射的可區分程度來看，在散射式能見度探測儀器中，工作波長介於0 . 86 m 2 m ，探測角度選取前向25度40度時，探測的結果將會是比較理想的。第三部分中，使用超橢球方程來統一描述各種非球形粒子的形狀，然後使用t矩陣方法計算了一些形狀的非球形粒子的近紅外散射特性。另外，在本文中還針對球形粒子的散射場提供了一種三維可視化方法，使對散射場強度的空間分佈的理解更加簡單，直觀。
  4. Atmospheric attenuation of scene contrast is studied theoretically on the basis of radiometric principles, and the relationships between the measured maximal detection range for a target and visibility distance under two possible conditions are obtained

    根據輻射度學原理，從理論上研究景物對比度在大氣傳輸中的衰減，得到了在兩種可能的條件下所測得的目標最大探測距離與能見距離的關系。
  5. As suspended particulates are carried and dispersed by the wind, reduced visibility is significantly influenced by meteorological factors such as wind direction, wind speed and atmospheric stability

    由於懸浮粒子隨風傳送及擴散，因此大氣傳送及擴散條件如風向風速及大氣穩定度對能見度都有一定影響。
  6. As it is made specifically for aviation purpose, it may occasionally differ from the night - time visibility for general purpose which represents the degree of atmospheric transparency and is independent of the intensity of lights being observed

    由於上述安排特別為航空用途而設，故此有時或與一般用途的夜間能見度不同。一般用途的夜間能見度代表大氣透明度，不受燈光強度所影響。
  7. Atmospheric moisture, dust, smoke, and vapor that diminishes visibility

    霧氣造成能見度降低的大氣潮氣、塵埃、煙霧以及水汽
  8. Information on atmospheric pressure, air temperature, humidity, wind speed and direction, rainfall, visibility, cloud and sea surface temperatures is used operationally in day - to - day weather analysis and forecasting

    日常天氣分析及預報工作中均要應用多種氣象資料，包括大氣壓力氣溫濕度風速風向雨量能見度雲量和海面溫度。
  9. Aerodrome observations including wind, air temperature, atmospheric pressure, visibility, cloud, and expected significant weather in the approach and departure corridors are also included in the automatic terminal information service broadcasts for aircraft preparing for landing at or taking off from the hkia

    機場氣象觀測資料，包括風向風速、氣溫、大氣壓力、能見度、雲量雲高資料及預計會影響飛機升降區的重要天氣，亦經由自動航站情報服務廣播發送予預備離開或降落香港國際機場的航機。
