  1. In this paper, firstly, by means of analyzing some rain attenuation experimental results, the raindrop size distributions applied to various climatic regions in china, are discussed

    首先通過分析雨衰減的一些實驗結果，討論能用於中國各氣候帶的雨滴譜。
  2. Using the dsd models and forward scattering amplitude computed by the least squares fitting method, the specific attenuations at l - 400ghz have been computed and analyzed, the parameters of " power law " relation between specific attenuation and rainfall rate are obtained. the specific attenuations in qingdao, guangzhou and xinxiang are compared with itu - r specific rain attenuation models

    利用平均雨滴尺寸分佈和點匹配法計算的雨滴的前向散射數據計算和分析了青島、廣州和新鄉地區1 ? 400ghz特徵雨衰減特性，得到了特徵雨衰減與降雨率的指數關系參數，並與itu - r （ internationaltelecommunicationunion - radiocommunication ）特徵雨衰減模式進行了系統的比較研究。
  3. The analytic specific attenuation model for rain for use in prediction methods are developed, the specific rain attenuations calculated by the analytic model are in high agreement with those by the parameters tabulated in itu - r model, this model has presented to itu - r as a proposed revision to current itu - r model

    基於itu - r特徵雨衰減模式的列表參數，提出了特徵雨衰減的解析模式，該模式計算的特徵雨衰減與itu - r模式列表參數計算結果間有很好的一致性，並提交itu - r作為國際標準審議。
  4. The specify attenuation, attenuation and scattering impairment of a melting layer have also been predicted at various rainfall for 6, 10, 20, 30ghz. the results calculated show that the attenuation due to melting layer are more than the attenuation induced by the identical thickness rain

    在6 、 10 、 20 、 30ghz時，計算了不同降雨率融化層的特徵衰減、衰減和散射損耗，結果表明融化層的衰減較同厚度雨區的衰減為大。
