Ultra windband synthetic aperture radar ( uwb - sar ) has a broad applications because it can produce fine images of concealed targets with the capabilty of penetrating the foliage and the surface of the earth. lt has been an important sign for acquiring high - resolution images of uwb - sar for real time processing, and the efficient imaging algorithm is the pivotal and the fundation
超寬帶合成孔徑雷達（ uwb - sar ）能夠穿透葉簇和地表實現對隱蔽目標的精細成像，有著廣泛的應用前景，高解析度uwb - sar圖像的實時獲取已成為成像雷達發展的一個重要標志，而高效成像演算法又是它的關鍵和基礎。We paid our main attention to cloning tb22kda gene from tartary buckwheat, expressing the structure gene and getting the purified recombinant protein, and these provide foundation for father study on the relationship between structure and function of the allergenic protein tb22kda, the orientation of the corresponding epitope and the exploration of allergenic reaction mechanism
本研究的目的在於分離克隆苦蕎中的主要過敏蛋白（ tb22kda ）基因，並表達純化出其結構基因編碼的蛋白。從而為進一步研究過敏蛋白tb22kda的結構與功能，尋找其中的抗原決定簇，探討過敏原與其相應抗體相互作用機理提供依據。Yuan kou, ph. d. ( 1990, cas ), research fellow ( 1986 - 1988, aots ), post - doc ( 1993 - 94, ucsd ), visiting professor ( 1997, kyoto university ), deputy director of osso state key lab, cas ( 1991 - 1997 ), now is a professor of chemistry, peking university, member of national committee for catalysis, member of national committee for petro - chemicals, project leader, member of 7 - experts committee, 973 project ( energy resources / environmental ), associate editor of chinese journal of catalysis
寇元，理學博士（ 1990 ） ，日本aots進修生（ 1986 - 1988 ） ，美國ucsd博士后（ 1993 - 1994 ） ，日本京都大學高訪教授（ 1997 ） ，原中國科學院osso國家重點實驗室專職副主任（ 1991 - 1997 ） ，現任北京大學教授，博士生導師，中國化學會催化專業委員會委員，中國化工學會石油化工專業委員會委員， 973多個項目的專家組成員，多家國內學術期刊編委， 《催化學報》副主編，長期從事溫室氣體催化轉化和納米簇結構及復制研究，提出表面配位化學/擔載催化劑無定形理論等。At first, this article introduces the dicom information model and dicom network protocol architecture ; specify the definition of dicom service and object, message data coding, encapsulation of protocol data unite ( pdu ) and the mechanism of message exchange, etc. and then synoptically specifies protocol data unite, presentation data value ( pdv ), encapsulation of various compose items and the class clusters for this program
本文首先介紹了dicom標準信息模型及其網路協議構架，並且深入淺出地介紹dicom的服務和對象定義、消息數據編碼、協議數據單元pdu （ protocoldataunite ）的封裝以及dicom消息的交換機制等基本原理。然後概括說明了模塊中的協議數據單元、表示數據值pdv （ presentationdatavalue ） 、各個組成條目的封裝以及在程序中為此定義的類簇。This algorithm adopts a middle ground between centroid - base and all - points - based approaches. instead of using a single centroid or all points to represent a cluster, a fixed number of representative points in space are chosen, these points represent and capture the geometry and shape of the cluster. in addition. the representative points of a cluster are generated by first selecting well - scattered objects for the cluster and then " shrinking " or moving them toward the cluster center by a specified fraction, or shrinking factor. the shrinking helps dampen the effects of outliers. therefore, cure is more robust to outliers
該演算法選擇基於質心利基於代表對象方法之間的中間策略，它不用單個質心或簇中全部對象米代表一個簇，而是選擇數據空間中定數目的只有代表性的點，這些點代表和捕捉到了簇的形狀。此外，由於引入了收縮因子使代表點向簇小心「收縮」而使該演算法能夠較好地消除孤立點的影響，在處理孤立點上也更加健壯。The total dna of exoconjugants acquired dna degradation phenotype during electrophoresis, which suggested that the dnd gene cluster was heterologously expressed. the phz1358 was used sucessfully as a vector for gene replacement to identify the biosynthetic pathway genes for nanchangmycin in s. nanchangensis ns3226. however, the gene replacement in another potential pks cluster has not succeeded till now
將利用phz1358構建的基因置換結構（孫宇暉，未發表）導入南昌鏈黴菌ns3226中進行了基因置換實驗，協助完成了南昌黴素生物合成基因簇的克隆，但對另一潛在pks基因簇的基因置換實驗目前還未能完成。分享友人
