  2. 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。
  3. The recombinants were constructed by transforming ppic9 a - xynb into p. pastoris gs115. the assay results revealed that the xylanase gene xynb was overexpressed and secreted effectually in p. pastoris. in 3l fermentor the expression level of xylanase xynba exceeded 1200iu / ml and the expressed xylanase had normal bioactivity. the molecule weight of xynba was determined as about 31kd which is higher than 23kd of original enzyme xynb from streptomyces olivaceoviridis a1. xynbb was gotten by deglycasylation of xynba, whose molecule weight returned to 23kd. we comparised the enzymatic properties of xynba expressed in p. pastoris, xynbb deglycasylated from xynba and xynb produced from streptomyces olivaceoviridis al : there was little difference among the three enzymes on optimal ph, the optimal ph of xynb and xynba were both 5. 2, the optimal ph of xynbb was 5. 0 ; the optimal temperature of xynb and xynba were both 60 c, while the optimal temperature of xynbb was 50 ? ; because of glycosylation the thermal stability of xynba was better than xynb and xynbb ; the specific activity of xynba and xynbb were 883. 88iu / mg and 832. 5hu / mg respectively, which were both lower than 2814. 45iu / mg of xynb ; the km values of xynb and xynba were similar to each other which were 21. 56 ( g / kg ) and 20. 87 ( g / kg ), while the km value of xynbb was 27. 10 ( g / kg ) ; the fmax of xynba and xynbb were 4568umol / mg. min and 5329umol / mg. min respectively which were lower than 27623 umol / mg. min of xynb ; additionally all of the three enzymes did not display cellulase activity. they all had well resistance to pepsion and trypsin, and were not sensitive to metal iron, surface active agent and chelating agent. the analysis of different xylans enzymatic hydrolysate revealed : by xynba, that the main constitutions of enzymatic hydrolysate of birch wood xylans were xylotriose and xyloquaiose, which account for 68. 43 % and 16. 50 % respectively, additionally there was 11. 79 % of xylobiose ; the main constitutions of enzymatic hydrolysate of corncobs xylans were xylobiose and xylotriose, which account for 81. 78 % and 11. 55 %. the result indicated that this xylanase was a kind of 1, 4 - b - d - xylanohydrolase and was fit to used in industrial procession of xylooligosacc harides

    進一步對xynba進行了脫糖基化處理得到xynbb ，其分子量恢復到23kd ，證明xynba是糖基化蛋白。通過對畢赤酵母重組表達的木聚糖酶xynba 、脫糖基化的木聚糖酶xynbb以及橄欖綠鏈黴菌a1所產原酶xynb之間酶學性質的比較發現：三種酶的最適ph差異不大， xynb和xynba均為5 . 2 ， xynbb為5 . 0 ； xynb和xynba的最適溫度均為60 ， xynbb降為50 ：在耐熱性上， xynba由於糖基化作用熱穩定性明顯高於未糖基化的xynb和xynbb ； xynba和xynbb的比活性分別為883 . 88iu mg和832 . 51iu mg ，明顯低於原酶的比活2814 . 45iu mg ； xynb和xynba的km值相當，分別為21 . 56 （ g kg ）和20 . 87 （ g kg ） ，而xynbb的km值較大為27 . 10 （ g kg ） ； xynba和xynbb的vmax相差不大，分別為4568 mol mg ? min和5329 mol mg ? min ，明顯低於xynb的27623 mol mg ? min此外三種酶均無纖維素酶活性，對胃蛋白酶和胰蛋白酶有很好的抗性，且對作用環境中的各種離子、表面活性劑、螯合劑不敏感。通過對不同木聚糖的酶解產物的糖份分析發現：以樺木木聚糖為底物時，酶解產物主要為木三糖和木四糖，含量分別為68 . 43和16 . 50 ，另外還含有11 . 79的木二糖；以玉米芯木聚糖為底物時，酶解產物主要為木二糖和木三糖，含量分別為81 . 78和11 . 55 。

    由於水產品生產的資源和勞動密集特徵，沿海海岸線長、人口多、欠發達國家水產品產量高，發達國家、海岸線短、內陸水資源相對稀缺的國家水產品產量低。由於水產品消費具有兩重性、水產品需求彈性大的特點，發達國家對水產品需求量大，而發達國家的資源較少分配到水產品生產上，這就決定了水產品國際貿易比較活躍，並且高價值水產品流向發達國家。由於水產品的易腐特性，國際水產品貿易主要品種為水產加工品。
  5. The conclusions are : under the case of monopoly, the enterprise has the ability to delay the investment, thus it can take the advantages of option value brought by uncertainty to select the optimal timing of investment in each phrase flexibly ; under the case of competition, enterprise will select the optimal investment timing by comparing the tradeoff between the benefits of option value and the strategic lost of competitor ' s preemption, because preemption of competitor will reduce the ability of enterprise to delay investment comparing with the case of monopoly, the enterprise usually invests early, hi the meantime, by comparing the outcomes of investment cooperation in the r & d phrase with that of competition, we can conclude that r & d investment cooperation is pareto dominant strategy, since enterprise can fully take advantage of the option value brought by uncertainty, and thus enhance the flexibility of decision - making

    得到的結論是：在壟斷情形下，企業具有延遲投資的能力，因而企業可以充分利用不確定性帶來的期權價值，在創新投資的各階段根據不確定性信息的獲得靈活地選擇最優的投資時機；在競爭情形下，企業延遲投資的能力受到局限，由於害怕競爭對手的佔先，企業為了獲得佔先效應，會考慮競爭對手的行為對自己的影響，通過在不確定性所帶來的期權價值與競爭對手的行為所帶來的戰略價值之間進行權衡，來選武漢理工大學博士學位論文擇最優的投資時機。與壟斷情形相比，一般企業會提早投資。同時通過分析說明，競爭企業間通過在創新投資的研究與開發階段進行合作，可以使兩家企業充分利用不確定性帶來的期權價值，增強決策的柔性，結論說明，合作創新投資是兩家企業的帕累托占優策略。

  7. To assess the medicinal value of cultural anisodus tanguticus, the contents of four bioactive tropane alkaloids, anisodine, anisodamine, scopolamine and atropine, in cultural and wild materials were determined by the hplc method. the results showed that content of each alkaloid in the aboveground parts of cultural and wild samples was lower than that in roots, and this explained why it was not the whole plant but the root that was used as medicinal materials. the content of each alkaloid in the roots of one - year cultural material was lower than that in the two - year plants. the discrepancy of the total of four alkaloids between one - year and wild plants is not significant. moreover, the total of four alkaloids, and the contents of anisodine, scopolamine, and atropine in two - year plants were higher than those in wild plant. thus there is medicinal value in the cultivated a. tanguticus as well as wild a. tanguticus, especially in the two - year cultural a. tanguticus

    為了評估人工栽培山莨菪的藥用價值，採用高效液相色譜技術對人工栽培和野生山莨菪的地上部分和根中具有生物活性的4種托烷類生物堿:樟柳堿、山莨菪堿、東莨菪堿和阿托品的含量進行了測定.結果表明無論是人工栽培還是野生植物，地上部分中4種生物堿含量均遠低於根，這解釋了人們為什麼用山莨菪的根而不是整株入藥.在栽培植物的根中，一年生山莨菪中各生物堿含量均小於二年生山莨菪，其根中4種生物堿總量與野生根相比差異不是很明顯;二年生山莨菪根中， 4種生物堿總量以及樟柳堿、東莨菪堿和阿托品含量均比野生的高.這說明人工栽培的山莨菪，尤其是二年生山莨菪，同野生山莨菪一樣具有一定的藥用價值
