  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、中歐紡織品貿易爭端的來龍去脈，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度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數?紡織服裝指數（ ti ）每一季度末的交易收盤價和若干種反映宏觀經濟變化的指標，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數等理論做實證分析，從而得知反映國內物價水平和國內外經濟景氣程度的經濟指標對紡織板塊上市值的沖擊比較明顯，且可知沖擊程度和時滯度，進而分析出涉外紡織企業所面臨的宏觀經濟風險;接著，從博弈論的角度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度安排;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;在一定程度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. The reflected wave will be received by the receive antenna and transferred to digital data. we can analyze the data that saved by the computer of gpr to deduce the medium ' s property, situation, location and so on. being a kind of nondestructive, untouched method, it has many advantages such as nondestructive, rapidness, simpleness and high precision, so it will have wide applications in the ways of examination, control and maintenance to road quality, especially for highway

    路用探地雷達是近幾年發展起來的、應用於公路無損檢測的一項新技術，它利用超寬帶脈沖電磁波對路面結構層進行探測，當雷達發射天線發射的電磁波在路面結構層中傳播時會在介電特性突變處產生反射和透射，反射回來的波經由接收天線接收並轉化為數字信號儲存起來，通過分析探地雷達回波信號來估計路面結構層的性質、狀態和位置等特徵。
  3. In this paper. flow properties of multistage fluidized - bed bioreactor with external circulation at a pilot scale is studied. according to characteristic analysis, the model of completely mixing reactor in series is introduced to characterize real reactor as a theoretical model. on the basis of analog computing analysis and discussion of theoretical model. by means of pulse tracer method, experiments on residence time distribution ( rtd ) have been done in different conditions including the change of tracer level, feeding flow rate and circulation flow rate. the result shows when the ratio of circulation flow rate and feeding flow rate amounts to at least 4, the flow properties of multistage fluidized - bed bioreactor with external circulation at a pilot scale is very close to the model of completely mixing reactor in series. an amendatory model has been established by the regression method

    作者首先在對反應器進行特徵分析的基礎上，建立了描述中試規模多級外循環流化床生物反應器流動特性的串級全混流模型，並對理論模型進行了模擬計算分析和討論，在此基礎上，作者分別在無循環和有循環（改變示蹤劑用量、流加流量和循環流量）的條件下，利用脈沖示蹤法對一到五級串聯外循環流化床反應器進行了停留時間分佈實驗，結果表明，在循環流量與流加流量的比值達到大於等於4時，中試規模多級外循環流化床反應器的流動特性接近串級全混流模型，通過數據回歸擬合的方法，建立了中試規模一到五級串聯外循環流化床反應器的流動模型。
  4. The paper describes a cw, non - cooling, digital all - solid - stated ld pumped nd : yvo4 driver which adopts microprocessor control, stability power of laser feedback and laser output power about 10mw. the system is composed of constant current source, soft diagram, protection, pulse schematic and laser power feedback loop. by combining appropriate hardware and software, we achieved, in our driver, a variety of protection features including the ability to suppress transients and reduce noise, relay soft and hardware over - current protection and overvoltage shut - off, we have obtained a continuously adjustable laser power output with high accuracy and stability
