  1. The supernatant fraction and the precipitation fractions were analyzed by western blotfor strain dh5 a / pkkfpga, 5 - 10 % pga precursors formed as inclusion bodies in the cytoplasm while no inclusion bodies formed in the periplasm, this suggested most pga precursors were transported to the periplasm and matured to active pga and indicated that the maturation of pga in strain dh5 / pkkfpga was limited by the translocation step

    Western印跡分析表明對于菌株dh5 pkkfpga ， 5 - 10的原前體青黴g素酰化酶在胞內形成了包涵體，說明其成熟的限速步驟在胞內的運輸階段，而菌株dh5 psmlfpga則無明顯包涵體形成，說明菌株dh5 psmlfpga改善了青霉素g酰化酶的合成流，因而其表達能力高於菌株dh5 pkkfpga 。
  2. 6 ), the process that h20 is adsorbed on the electrode surface and the hydroxyl group is formed to oxidize the co may be the rate - determining step ; in the region iil ( logi > l. 6 ), all of the tafel curves show a curvature until the current densities reach the peak value, indicative of a possible limiting current. the effect of rare earth elements on methanol electro - oxidation has not been reported in literatures

    在低極化區（ logi 1 . 3 ） ，甲醇發生脫氫反應並形成反應中間體，其中co成為未被氧化的毒物，此過程成為速率限制步驟；在更高的極化區（ 1 . 3 logi 1 . 6 ） ， h _ 2o吸附在電極表面並解離生成[ oh ] ，促進了co的氧化，此為此階段速率控制步驟：在第3個極化區（ 10gi 1 . 6 ） ， tafel曲線發生彎曲，電流密度也最終達到峰值。
  3. In order to break down the rate - limited steps in the artemisinin biosynthesis to improve the artemisinin production and realize the industrial production of artemisinin, related key genes in artemisinin biosynthesis must be cloned and the regulatory patterns of key genes should be studied. for this purpose molecular cloning of related key genes in artemisinin biosynthesis was performed in this thesis work

    利用現代分子生物學和基因工程技術手段，克隆青蒿素生成途徑的關鍵酶基因，研究關鍵酶基因對青蒿素生物合成的調控規律，是打破青蒿素生物合成的限速步驟，大幅度提高青蒿素含量，最終達到利用植物生物技術工業化生產青蒿素的目的必須解決的關鍵問題。
  4. First according to the fact that tangential components of the evolution do not affect the geometric shape of the evolving curves, we introduce the evolution equation of geometric quantities for the general planar curves. then we describe the work of gage - hamilton briefly. last we consider a special curvature flow of curve which evolves with speed function of the principal curvatures along the inner norm and show that convexity of the curve is kept and its length and area are contracted if the initial closed curve is smooth and convex. so the final shape of the curve will be a point in finite time

    首先根據曲線在切向分量上發展是不影響曲線的發展形狀，我們引入了曲線的一些幾何變量的發展方程；其次我們簡要地回顧gage - hamilton研究曲線發展的一般步驟；最後我們考慮沿曲線的內法線以曲率的函數為發展速度的一類特殊的曲線族，證明了在初始曲線為凸的閉平面簡單曲線條件下，曲線將保持凸的，並且它的面積和周長將同時收縮，並在有限時間內成為一個點。
  5.
