  1. In this article, firstly the background of the textile trade conflicts within sino - us or sino - euro are introduced, thus learn that how to discern and dodge the foreign trade risks, how to choose the appropriate investment projects have already become one of the most important questions for exporting companies on foreign trade affairs well - known as high investment and high risk. so the main text makes a risk analysis qualitatively and quantitatively on a textile - exporting trading company from three angles of statistic 、 game theory and portfolio theory, which is the main content that we studied. firstly, the statistic article adopts data of the transaction closing price of the textile clothing index in shenzhen stock exchange at the end of each quarter as well as several other kinds of data reflecting the macro - economic changes, performs an empirical analysis of these data according to the theory of co - integration test 、 granger cause test and impulse response function of time series in economitric, and learn that the impact to ti is more obvious by the economic index reflecting local commodity price level and economic prosperity degree home and abroad, as well as the impact degree and the time lag degree, and knows the macro - economic risks faced by textile business enterprises ; after that by the game theory angle we analyze exactly the managing risks faced by one textile export corporation named beauty. from the game expansion chart the system arrangement between censor ways by exportation goal countries and exporting strategies by the exporting enterprises has been analyzed. involving the benefit assignment between them both the limited rounds and infinite rounds negotiations of cooperation games have been studied, and then country responsibility and the enterprise managing risks on foreign trade affairs and so on have been analyzed exactly ; in order to realize the investment multiplication in the certain degree to disperse the risk, the

    本文首先介紹了中美、中歐紡織品貿易爭的來龍去脈,由此可知在涉外貿易這種以高投入、高風險著稱的行業里,如何甄別和規避外貿風險、如何選擇合適的投資項目已經成為外貿企業的首要問題。因此,正文分別從統計學、博弈論和投資組合三種角對涉外紡織品貿易公司風險進行了定性和定量的分析,這也是本文的主要研究內容。首先,統計學篇選取了深圳證券交易所行業分類指?紡織服裝指( ti )每一季末的交易收盤價和若干種反映宏觀經濟變化的指,利用計量經濟學中時間序列的協整檢驗、 granger因果檢驗和脈沖反應函等理論做實證分析,從而得知反映國內物價水平和國內外經濟景氣程的經濟指對紡織板塊上市的沖擊比較明顯,且可知沖擊程和時滯,進而分析出涉外紡織企業所面臨的宏觀經濟風險;接著,從博弈論的角具體分析一家紡織品出口公司( beauty )的外貿活動所面臨的各種經營風險,該篇從博弈擴展圖入手,分析了出口目的國審查方式與本企業出口策略之間的制安排;並圍繞雙方的利益分配,研究了有限回合和無限回合合作談判博弈,然後具體論述了國家責任和企業涉外經營風險等問題;在一定程上為了實現投資多元化來分散風險的目的,投資組合篇從經典的markowitz模型著手,在一些特定條件的限制下,給出了一個相應的投資組合模型。
  2. ( 2 ). according to the system indices and requirements together with the technology characteristic, it researches the capture possibility of apt capturing system. then it introduces the common scan methods, such as raster, spiral, raster spiral, rose and lissajo.

    其中對幾個關鍵部分進行了詳細分析:計算了目角反射器的激光雷達散射截面( lrcs ),研究了qd與ccd對目位置角的計算方法和空間解析; ( 2 )根據系統指和要求並結合現有國內技術特點研究了apt捕獲系統掃描的捕獲概率問題,然後分析了幾種常見的掃描方式:矩形( raster )掃描、螺旋( spiral )掃描,矩形螺旋( rasterspiral )掃描,玫瑰形( rose )掃描以及李薩如形( lissajo )掃描; ( 3 )對分行掃描和螺旋掃描進行了詳細的模擬分析,分析了它們在不同捕獲分辨角、捕獲范圍、振動角振幅和終位置分佈均方差時的捕獲概率、捕獲時間與系統常之間的關系。
  3. A full mathematical model of optimal flow pattern design withengineering constraints was put forward, based on modern optimal control theory. an optimal flow pattern design was presented for optimizing meridional channel of axial flow turbine. according to integral optimization of turbine stages, a full physical model and mathematical expression were put forward for proposition of optimal flow pattern, including all performance parameters in turbine stages. this problem was further recast into a typical form control to maximize specific performance index such as work or efficiency of stage with given initial state, fixed terminal condition and constraints for part of state terminal variables. the program was also worked out according penalty function method and conjugate gradient method. the optimal distribution of c1ur1 ( r1 ) was obtained according to constraint conditions and maximized objective function

  4. Cf is a kind of non - different recommendation to all customers, so it is may appear that the company spend much cost but have little revenue. recently a new recommend technology base on lifetime value of customers have emerged, the centre of the technology is to use the weighed sum of the three variable to classify the customers and the reason of use weighed variable is that think about the relative important degree. then we can recommend products according to the association rule in the classify of same clv. the shortcoming of this recommendation is that the recommendation may have some error when the customers ’ data is not enough to form regular value

    近年來出現了一種採用基於客戶生命周期的加權rfm (表示客戶生命周期的三個指變量)技術的推薦方法,這一技術的核心思想就是採用這三個客戶屬性變量的加權和的方法來對客戶進行聚類,其中為變量加權是考慮到不同變量對顧客產生的不同重要程的影響。對符合某一生命周期類型的客戶按照商品挖掘關聯技術進行商品推薦。這種推薦方法的弊在於當客戶的交易據不足以形成規律化的量時,推薦可能會出現偏差。
  5.
