A novel distribution network optimal control approach for load balancing is presented based on the simplified model of distribution system, in which tie switches are regarded as critical elements. the two feeder lines connected with a tie switch are regarded as a feeder couple. load balancing ratios of feeder couples and total distribution network are defined and be used as indice of network reconfiguration, respectively
提出一種以聯絡開關為核心的用於負荷均衡化的配電網路優化控制方法，將每個聯絡開關對應的兩條饋線看作饋線偶，定義了饋線偶和配電網的負荷均衡率，並以此作為網路優化的評價函數，這樣配電網路重構過程就由若干饋線偶內負荷均衡化過程組成，在此基礎上發展了以負荷均衡化和降低線損為目標的配電網優化方法。 -
Organic acids can thus substantially affect the amounts and ratios of elements going into solution from minerals.
因此有機酸對各種元素從礦物進入溶液的數量和比率都起著重大的影響。 -
Based on an statement of relative elements of life insurance and analysis of some key concepts, the thesis firstly sums up, compares and analyzes the commercial life insurance supply market in china from two aspects : company and product ; secondly, it introduces a method of measuring one ' s insurance demand, expound the methods and strategies of how to choose a company or a product : how to choose a company is to calculate, compare and analyze the ratios of debt and profit, which are based on statements of assets and debts and statements of losses and profits. a choice is made finally according to the above results ; how to choose a product include the methods of comparing all kinds of policy cost, and a empirical analysis is made for term policy cost, in addition, on basis of the present situation of life insurance market in china, author bring forth a simple way to choose participate insurance
本文在闡述有關壽險基本知識並剖析其中關鍵概念的基礎上，首先從壽險公司和壽險險種兩個方面對中國商業人壽保險供給市場進行了歸納、比較和分析，接著介紹了確定保險需求的方法以及選擇壽險公司和險種的方法和策略：選擇壽險公司的具體方法是以各壽險公司的資產負債表和損益表為依據，計算出並比較分析各公司的償債比率和盈利比率，來考察其償債能力和盈利能力，最後根據結果做出相應選擇；選擇壽險險種的方法包括比較各類壽險保單成本的方法，本文對其中的定期壽險保單成本進行了實證分析，並根據中國壽險市場的現狀，提出了選擇分紅險的簡易方法。 -
