Specially, based on risk - metric and factor variables, the author discusses multi - factor asset pricing model. in theoretical analysis, the author attempts to release the assumption of index ' s random walk, proves a portfolio selection model suitable for the linear index level moreover, based on assets un - exchangeable, the author brings forward asset pricing models for b - shares, h - shares and non - circulated - shares. the author also brings forward multi - factor asset pricing model based on risk - metric indices, such as coefficient of beta, standard variance, standard semi - variance, average absolute deviation, value at risk, and factor variables, such as circulated market equity, exchange ratio, short - term historical return
在理論分析時，作者嘗試放鬆指數水平滿足隨機遊走過程的假設，推導出指數水平呈線性趨勢的資產組合選擇模型；此外，作者基於資產不可交易這一假設，提出了b股、 h股和非流通股等情形的資產定價模型，並基於系數、標準差、標準半方差、平均絕對離差和風險價值等風險度量指標以及流通市值、換手率、短期歷史收益率等因素變量提出了四因素資產定價模型。 -
Based on this extended model, we then propose an oblivious algorithm that can route messages between any two nodes in o expected number of hops. our routing algorithm keeps only o beta 1 bits of information on each node, where 1
Kleinberg證明了如果每個節點只用local的路由信息，簡單的貪婪演算法可以在o lg n 2的期望時間內完成任何兩點間的路由過程。 -
After getting the standard difference and beta index of after risks, it gets three measuring figures : shape performance index, treyner performance index and jesen performance index through establishing the after feature line model, and compared them. finally, combining with the present situation of investment fund in china, using the investment fund performance evaluation research at home and abroad as the reference, adopting indexes such shape, treyner, jesen, stock net selection rate and c value, it evaluates the performance of investment funds in china in four aspectsxomprehensive performance measurement of investment funds. stock selection capacity. market opportunity seizing capability and investment portfolio ; and mares a case analysis on the ten representative funds in china
最後，結合我國的投資基金的具體現狀，借鑒國內外同行對投資基金績效評估的研究，運用夏普業績指數、特雷諾指數、詹森業績指數、股票凈選擇率、 c值等指標，從投資基金的綜合業績度量、股票選擇能力、市場時機把握能力和投資組合分析四個方面對我國投資基金的績效進行了評估，並對在我國投資基金中有代表性的十隻基金進行了實證分析。 -
From the most common perspective of seo, this paper researched the changes of prices of shares before and after the notice day. using capm model on analyzing the market value of the portfolio yield and beta value to certificate the company ' s stock performance, it shows that the variables of the classic theory lack explain ability for the unusual price fluctuations
本文從配股這種最普遍的再融資方式出發，通過研究配股公告日前後股票價格的變化，運用capm模型對市場組合收益率和貝塔值對配股公司的股價表現進行了驗證，發現經典理論中的解釋變量對股價的異常波動缺乏足夠的說服力。 -
Measuring of market risks was generalized into beta coefficient, duration and convexity of bond risks, delta and var approach. methods of measuring credit risks were classified into classic models and modern credit measuring model. kmv model and creditmetrics model are the two most popular models in western countries
將市場風險的度量方法歸納為股票的風險度量beta系數，債券風險的度量持續期和凸性，金融衍生工具風險的度量delta等指標以及綜合度量市場風險的var方法；將信用風險的度量方法歸納為古典模型（專家制度和z計分模型）和現代信用風險度量模型（信用度量制模型等） 。 -
Based on 0 - d core physics model, the core parameters of low, moderate and high aspect ratio are calculated by system code. in addition, an advanced plasma configuration for fds system has been proposed, which aims at high beta, high bootstrap current and good confinement. in order to determine the feasibility of fds operation, a two - dimensional time dependent free boundary simulation code has been adopted to simulate time - scale evolution of plasma current profile and boundary position
在建立零維堆芯物理模型基礎上，利用系統分析程序計算了堆芯物理參數，分析了fds -標準環徑比情況的先進運行模式，並對其位形演化進行了放電模擬，獲得比較滿意的結果，為fds -系統概念設計奠定了基礎。
