  1. 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。
  2. Based on theory and software of gis, the thesis do some application research on the application of geographic information system to transportation planning, which is pertinent to characteristic of transportation planning and combined with actual circumstance of traffic zone and road network in certain city. during the process of transportation planning and by theoretical base and software development system of gis, basal database is founded, which consists of spatial database and attribute database in information system of transportation planning. the system provides corresponding tools for editing and modifying graph data and can flexibly do some operations such as adding, deleting and modifying and so on

    本論文就地理信息系統在交通規劃中的應用進行了研究，在gis的理論基礎和軟體開發平臺的基礎上，針對交通規劃的特點進行了gis的二次開發，結合某城市主城區交通小區和道路網路的實際例子，建立交通規劃信息系統的基礎數據庫，包括空間數據庫和屬性數據庫，並提供相應工具對圖形數據和屬性數據進行編輯和修改，可以非常靈活地對它們進行增、刪、改等操作，對交通規劃的前期預測、交通需求預測、交通分配及規劃方案的評價進行了探討，最後，對交通規劃成果進行可視化輸出，如製作各種專題圖，從而將地理信息系統和交通規劃結合起來，形成交通規劃信息系統，將交通規劃中具有空間特徵的信息進行可視化表達，為信息利用者提供直觀、清晰、全面的信息表達方式，提高了交通規劃決策的科學性和合理性。
