  1. The results of numerical experiments, using the four - dimensional variational data assimilation system of the nonhydrostatic mesoscale model mm5, show that : the tangent linear model and adjoint model conducted by keeping the " on - off " switches the same as the basic state, can provide a good approximation of the first - order information to the nlm perturbation and a good descent direction for the minimization procedure ; switching on and off at every other time step in the kuo cumulus parameterization scheme do n ' t impact the convergence rate of cost function ; the existence of the switches do n ' t impact improvement to the mm5 model rainfall prediction because that not only specific humidity, but also wind, temperature and pressure are assimilated into the model

    非靜力中尺度數值模式mm5的四維變分資料同化系統進行的數值試驗結果表明: 「開關」變量保持與基態一致,所構造的切向線性模式夠提供關于非線性模式擾動的一階近似,伴隨模式所計算的梯度值夠為最小化過程提供較好的下降方向;郭氏降水參數化方案中對流每隔一個積分步的交替發生並影響目標函數最小化的速度; 「開關」變量的存在也影響將風、溫度、壓和比濕結合起來同化對mm5降水預報準確性的提高。
  2. As the essential electrical calculation means, load flow calculation provides important basis for power systems operation and studies, and is indispensable to advanced power systems application software. in this thesis, the development of methods for load flow solution of distribution networks at present have been fully analyzed and evaluated in the aspect of convergence. the algorithm for distribution power systems base on the complex matrix was proposed in this paper, the proposed methods is very efficient and required less computer memory storage observably

    潮流計算是電力系統中應用最廣泛、最基本,也是非常重要的一種電計算。它給電力系統的研究人員和實際運行人員提供了重要參考依據,也是許多電力系統高級應用軟體中可缺少的一部分。本文針對配電網潮流計算的現狀進行了全面分析,深入討論了目前各方法的特點,並從及各方面指標進行了比較分析,提出了基於復數矩陣的配電網潮流的原理、數學模型和實現方法,並通過編程于以實現。
