The enzyme 5 - enolpyuvyl - 3 - phosphoshikimic acid synthase ( epsp synthase ; ec2. 5. 1. 19 ), encoded by anoa locus, is a key enzyme present in microorganisms and plants where it has a function in the biosynthesis of aromatic amino acids. glyphosate ( n - phosphonomethyl - glycine ) is an effective non - selective, broad spectrum, postemergence herbicide, which has been shown to inhibit epsp synthase activity in a competitive manner. glyphosate tolerant plants can be mediated by either overproduction of the target enzyme or by the presence of an altered enzyme
植物和微生物芳香族氨基酸生物合成過程中的一個關鍵酶? ? 5 -烯醇丙酮莽草酸- 3 -磷酸合成酶（ epspsynthase ； ec2 . 5 . 1 . 19 ）由aroa基因編碼，該酶受廣譜滅生性、內吸傳導型除草劑草甘膦的競爭性抑制，將epsp合成酶基因轉入植物中可獲得草甘膦耐受植株。 -
Since the discovery of cnt ’ s and find that cnts have small diameter and high length diameter ratio and can be look as one - demission material, it can be used as emission emitter of fed. especially, the aligned cnts array can be seen innumerable single cathodes which are lined regularly and form array. so growing aligned cnts array in selective area is the key technology to product cnts fed, which is also the necessary condition of cnts micro - electronics device
自碳納米管發現以來，由於碳納米管的直徑很小、長徑比大，故可視為準一維納米材料，可作為場發射平板顯示的尖端發射體，特別是定向碳納米管陣列可看成是無數根單尖陰極規則的排列起來形成陣列式，是理想的場發射平板顯示器的尖端發射體。 -
The protein level of p21 increased lightly from 1 to3 h, then decreased at 6 - 9 h, reached maximum at 24 h after 2gy, it increased from 3 to 24 h exposed tology, and the protein level of p21 associated with cdk2 increased, which did not inhibit the cyclin e / cdk2 kinase activity, because of upregulation of cyclin e and deregulation of p27kipl after irradiation. in contrast to p21, p27kipl may be a key regulator of cyclin e / cdk2 activity in dna damage responses. hi the ubiquitin - proteasome pathway invovled in regulation of p27kiplexpression in response to ir the ubiquitin - proteasome pathway regulated selective and time - controlled elimination of p27 kipl
與p27ki 」 ，表達水平不同， pzi蛋白表達水平在zgy照射后略有增加， 6一gh略有下降，在照后24h達到最大; 10gy照后1一3h開始增加，持續到24h ，並且cycline / cdkz復合物中pzi蛋白結合增多，但cycline / cdkz激酶活性並未受到抑制，除了因ir誘導cydine蛋白表達水平增加外，另一重要的原因就是與pzi同一家族的p27kip ，蛋白表達水平下降，失去了對cycline / cdkz的抑制活性。 -

The mssr mode s technology, which was introduced firstly for the purpose of air tranfic control ( atc ) system, is based on the individually addressing and selective interrogation technology. the mode s can overcome many problems exist in mode a / c, such as signal interference, limited aircraft identification, garble and fruit, and provides the ability to build digital data link. many countries and organizations do them best to support researches about the communication, navigation and surveillance technology, which are all based on the mode s, and many productions have been adopted step by step by the international civil aviation organization ( icao ). so, to research the key technologies of mode s will contribute a lot to the development of domestic aviation system, especially for the air control system, identification friend foe and navigation system
它建立在獨立編址、選擇性詢問的基礎之上，能夠解決在模式a / c中存在的信號干擾、有限的信息編碼、幻影（ garble ）和異步應答（ fruit ）等問題，同時在數據鏈路方面有著巨大的潛力。國際上，模式s的數據鏈技術得到了廣泛的關注，許多國家和組織大力支持基於模式s的通信、導航和監視技術以及航空管理新技術的研究，許多成果正逐步被國際民用航空組織（ icao ）所採用。因此，對模式s核心技術的深入研究對於我國在航空管理、敵我識別、導航等方面的發展有著重大的意義。 -
This thesis describes the key techniques of mode s ( selective ), basic concept and its implementation. the respondent technology of mode s is based on the 24 bits address identifier of a plane, which could be used to detect the plane by the datalink, get the planes ’ property to identify, deal with the overlapping of several planes ’ replies
模式s的應答技術建立在對飛機的24位地址進行身份確認的基礎上，能用更好的鏈路預測來探測飛機，而且能同時得到有助識別飛機的屬性數據，能夠處理多架飛機應答數據交疊的情況。 -
