  1. Human bone morphogenetic protein 3 is a member of tgf - b superfamily. lt can induce the differentiation of cartilage and bone tissue in mesenchymal cell. and is important to bone self - repairment and bone development during embryo morphogenesis. in addition, some other biological activities of hbmp - 3 have also been found. such as inducing development of embryo and stimulating differentiation of neural and blood cells. therefore, there is a great prospect in the use of hbmp - 3. there is trace content of hbmp - 3 in human body. it has been expressed in the expression system of eukaryotes and prokaryotes respectively, but its application is restricted because of defects in the process and modification after translation in prokaryotic cells and higher costs and lower yields existed in eukaryotic expression system

    人骨形成蛋白3 （ hbmp - 3 ）屬于tgf -超家族的一員，可以誘導間充質細胞分化為軟骨和骨，在胚胎時期骨骼發育和骨再生修復中起著重要的作用，而且對胚胎發育過程中中胚層的誘導和分化、造血組織的發育以及神經系統的發育和修復等都起著重要作用，因而hbmp - 3有廣闊的市場前景。它在人體內含量極微，盡管研究人員已經在原核細胞和真核細胞表達系統中分別進行了表達，但是由於原核表達系統缺乏翻譯后的加工修飾，真核表達系統存在成本高、產量低等特點，限制了其在臨床上的應用。
  2. The complex model of luminescence centers and quantum confinement has been proposed to interpret the origin of the green and red - emitting of the ps after modification. the deduction is supported by analyzing the morphology and the surface species of the modified samples through afm, sem, and ftir, xps

    通過afm 、 sem及ftir 、 xps對這兩種多孔硅樣品進行表面形貌和化學成分分析，採用發光中心（ lc ）量子限制效應的復合模型對上述修飾多孔硅的pl峰移現象進行了理論說明。
  3. At the same time, vp4 gene was mutated in a certain point by pcr. the plant expression vector : pbi121 was constructed and then transformed to agrobacteriutn tumefaciens eha105 directly. a. tumefaciens eha105 harboring pbi121 / vp4 was used to transform the boechmeria nivea l. guad according to the leaf disc procedure

    為便於基因操作，對外殼抗原蛋白vp4基因進行適當的修飾和改造：通過引物設計，利用pcr反應，在基因的起始編碼前引入有助於真核生物表達的kozak序列和限制性內切酶位點；使用套疊pcr對vp4基因進行定點突變，以便於將改造后的基因插入pbi121構建植物表達載體，通過直接轉化法，把pbi121 vp4轉入農桿菌eha105 ，構建了農桿菌工程菌。
  4. Nation modified platinum electrode ( 1 ) the nitric oxide in the medium of natural seawater was determined using nafion modified platinum electrode for the first time, the best conditions are found as follows : the time of exclusion of oxygen bubbled with nitrogen for the electrochemical cell is 30min, the preparation time of saturated solution is 30min, the enrichment time is 5min and the electrochemical responses of the modified platinum microelectrode to no were evaluated by scanning from 0. 2v to iv

    主要研究結果如下：一、 nafion修飾鉑電極1首次用nafion修飾鉑電極對天然海水介質中的一氧化氮進行了測定，確定了最佳實驗條件，即反應池通氮除氧30min ， no飽和溶液的制備時間為30min ，富集時間是5min ，電位掃描范圍0 . 2 1 . 0v ，並且確定了nafion修飾電極的檢出限是1 mol l ，線性范圍1 76 . 9 mol l ，相關性良好。
