The tuning curve of type - i phase matching of bbo opo are measured with accuracy ; the maximum conversation in total of the system is about 31 % at 615 . 6 nm , and it is fitted well with the gtp formula ; in the end we compared the output linewidth and unstable cavity far field beam qua lity of the bbo opo under the condition of type - i phase matching and type - ii phase matching , it is proved that we can obtain the parametric output of linewidth less than 0 . 3 nm and the beam divergence angle approaching diffraction limits by take the advantages of type - ii phase matching and unstable cavity designs 測量了該系統的轉換效率最大為31 ,并能與理論公式極好地吻合,最后比較了在類相位匹配條件下和類相位匹配條件下的bbo - opo的輸出線寬,以及非穩腔的遠場光束質量,實驗結果表明,利用類相位匹配以及非摘要穩腔設計可以獲得線寬小于0 3nlm 、光束發散角接近衍射極限的參量光輸出。

In this paper , we selected a widely used organophosphorous pesticide - - monocrotophos , used goldfish as model animal , and chose the vitellogenin induction of male fish as the main indicator , - gtp of sertoli cell in testes , the changes of microstructures of testis and ultrastructures of pituitary and testis as assistant indicators , we finally built up a screening system to effectively detect the environmental estrogen effect of organophosphorous pesticides , and reported that the monocrotophos had the activity of environmental estrogen for the first time in the world 因此,本文選擇國內廣泛使用的有機磷農藥? ?久效磷,以金魚為模型生物,以雄性金魚卵黃原蛋白產生、精巢支持細胞- gtp酶活性,并輔以生殖軸線器官? ?垂體和精巢超微結構的變化,在國內首先建立了有機磷農藥環境雌激素效應的篩選體系,并首次確認久效磷具有環境雌激素活性。

It seems to be true that the prevailing and ramification of gtp has seriously affected the international trade pattern and attracted much attention at home and abroad . but literature shows that , up to date , gtp has n ' t been formally and systematically investigated as a trade protection theory 本文分析綠色壁壘對我國農產品出口的影響,全文共分為三大部分:首先,本文回顧貿易保護主義演變軌跡,應用貿易保護理論較為系統地論述了綠色貿易保護主義的歷史必然性及其對國際貿易的影響,并對引力模型進行綜述。

Firstly , the author describes the gprs network architecture , its main network entities , and the interfaces , protocols . the umts architecture is simply explained in this part . secondly , the article gives a detail discussion to gtp protocol and each important communication process between gsns 首先,作者詳細介紹了gprs網絡結構、主要的網絡實體,相關接口的信令平臺;同時考慮到課題研究的延伸性,對第三代移動通訊系統中最有代表性的wcdma網絡結構(核心網與gprs一致)作了簡要的介紹。

Rapl belongs to ras superfamily of small gtp - binding proteins , which is considered to control cell growth , differentiation and survival . rapl was regarded as an antagonist of ras because it can revert the phenotype of oncogene ras transformed cells . recent researches show that rapl has its ras - independent functions in a variety of cellular systems besides its effect as an antagonist of ras Rap1除具有逆轉原癌基因ras激活突變體所導致的細胞形態改變而被認為是ras的拮抗物外,最近的研究還發現rap1在一系列的細胞系統中有獨立于ras之外的功能,如控制與細胞粘附有關的事件等,因而成為研究的熱點。

Homologues of era have been identified in prokaryotes and eukaryotes . there are two domains in era : the n - terminal gtp - binding domain and c - terminal rna binding kh domain . era plays an important role in cell cycle progression at a specific point in the cycle , after chromosome partitioning but before cytokinesis Era是在原核和真核生物以及植物中普遍存在的g蛋白,是一個結構上既具有gtp結合結構域又有rna結合結構域、不同于ras的獨特的新的g蛋白亞家族。

And thirdly , it discusses the monitor system architecture of gn interface between gsns , and explains the offered statistic items of gn interface monitor system base on the characteristics of gtp protocol 接著,文章詳細分析了gtp協議,及gprs支持節點間的信令配合過程。然后根據gtp協議的功能特點,提出gn接口監測系統的結構,提出系統應完成的監測統計項目。

The contamination of isotope is an important factor that affects radioactivity isotope tracer injection profile logging , and the application of “ gtp tiny ball without radioactivity “ is an efficient way to eliminate contamination of isotope 摘要同位素沾污是影響放射性同位素示蹤注水剖面測井的一個重要因素,采用“冷球”是減少同位素沾污的一種有效手段。

To insight the function of raplgap and the mechanism of raplgap hydrolyzing gtp to gdp , yeast two hybrid system ( y2h ) was employed to look for the potential proteins that interact with raplgap protein 為了研究rap1gap的作用機制及rap1gap在信號轉導中的作用,我們應用酵母雙雜交體系( yeasttwohybridsystem )尋找潛在的與rap1gap相作用的蛋白質。

The damages of monocrotophos on tnicrostructure of testis were that it caused the deficiency of ground membrane , hypertrophied leydig cell and spermatogenous . besides , the y - gtp activity was inhibited by monocrotophos 久效磷對金魚精巢組織結構的破壞主要表現為:精小葉基膜斷裂; leydig氏細胞出現肥大現象;精原細胞膨脹。

As a kind of gtpas , ftsz can intergrate to filamentation or tube when depending - gtp . in fact it is a 400aa bacteria conservative protein whose structure and function similar to that of tubulin ' s 在細菌中ftsz是一個重要的胞漿移動細胞分裂蛋白,在細胞膜內表面分裂的地方形成一個環狀結構,起支架作用并在分裂結束后分解。

Ftsz also be a key cytoplasm moving cell division protein . on the cell membrane division site where it forms a ring - like structure which acts as a framework and disassembled when cell division finished Ftsz是一個gtp結合蛋白,具有gtpase活性,在依賴gtp時聚合形成絲狀體或管,它們在隔膜合成時起骨架作用。

Within this backbone , the gsns encapsulate the pdn packets and transmit ( tunnel ) them using the gprs tunneling protocol gtp . the interface between gsns is called gn / gp interface Gprs網絡中增加了gn 、 gp 、 gb等多個接口和網絡實體,其中gsn間的接口稱為gn或gp接口。

By co - transfection of the mutants with full - length raplgap , we found the mutant at 82 position could still bind to full length raplgap , while the mutants a 本文采用a衛中標記的gtp與純化的rapla共孵育,使rapla全部與放射性同位素標記的gtp結合。

Like all the previous protectionism in the history , green trade protectionism ( gtp ) was been created to serve the interest of the ruling makers 從貿易歷史上看,貿易保護主義的每一次新涌動都是有著明確的利益取向。
