The thesis , somehow , is a summary , which expounds the main contents of traditional portfolio theory ( tpt ) and mpt , also gives a comparison between tpt and mpt ; analyses two aspects of markowitz theory , one is the effects of risk disperses and the demonstration , the other is how to make an optimal portfolio strategy ; researches into capital assets pricing model ( capm ) , factor model ( fm ) and arbitrage pricing theory ( apt ) respectively in three parts ; studies another two parts , one is the premise of mpt , which is the efficient market hypothesis ( emh ) , the other analyses the behavior finance theory ( bft ) produced in the background of challenging and querying to emt and capm . the thesis finally discusses the researching and applying prospects of mpt in china 論文對現代資產組合理論與傳統資產組合理論分別進行了分析,并對兩者進行了比較研究,對馬克維茨的均值? ?方差理論從資產組合風險分散效應和最優資產組合選擇兩方面進行了重點分析,對資本資產定價模型、因素模型、套利定價理論進行了一定深度的分析和研究,對現代資產組合理論的前提假設? ?有效市場理論及在對有效市場理論和資本資產定價模型形成挑戰和質疑背景下提出的行為金融理論進行了論述,論文最后分析了現代資產組合理論在我國的研究及其應用的廣闊前景。

Motivated by this observation , this paper studies the problem of efficiently processing k nn k - ge 1 search on r - tree - like structures storing historical information about moving object trajectories . two algorithms are developed based on best - first traversal paradigm , called bfp k nn and bft k nn , which handle the k nn retrieval with respect to the static query point and the moving query trajectory , respectively . both algorithms minimize the number of node access , that is , they perform a single access only to those qualifying nodes that may contain the final result 例如,若已知動物的軌跡,則動物學家可能提出如下兩種查詢: i在時間區間ti , tj內找到離一個給定的靜態點譬如食物源實驗室等最近的k條動物軌跡ii在時間區間ti , tj內找到離一條預先指定的動物軌跡最近的k條動物軌跡。
