親電反應 的英文怎麼說
中文拼音 [qīndiànfǎnyīng]
親電反應
英文
electrophilic reaction-

對于親電取代反應，酚基基本上以同氨基一樣的方式使芳環強烈活化。The determination of human thymidine kinase ( htk ) in human serum, which is a key indicator of cancers can give information for the diagnosis and treatment of the malign diseases. the protein a layer was first self - assembled onto the gold electrode surfaces of quartz crystals, the monoclonal antibodies were then orientedly immobilized through the specific binding between the fc terminals of the antibodies and the self - assembled protein a. with this sensor, the affinity constant of antigen - antibody binding was estimated to be 1. 85 106 l / mol according to the scatchard ’ s plotting method, which proved the high bioactivity of antibody. finally, an amplified piezoelectric immunosensor was designed to determine the htk in
實驗中將蛋白a吸附於鍍金壓電石英晶體電極表面，用於定向固定htk單克隆抗體，成功研製了檢測htk的壓電石英晶體傳感器，並基於標準scatchard繪圖法，計算出免疫反應的親和常數為1 . 85 106l / mol ，證明該單克隆抗體具有較高的免疫活性;同時基於酶催化沉澱技術，設計了的檢測htk的質量放大壓電石英晶體傳感器，該傳感器可在0 . 1 - 10ng范圍內對htk進行定量檢測，應用此傳感器成功地對5種癌癥病人血清中htk的濃度進行了測定，實驗結果為癌癥的臨床診斷與治療提供了參考。Currently, dennis is working on producing a movie about his father ' s life. this feature film will star usher. the film is set to start shooting late 2006
現在丹尼斯正在主導拍攝一部反應他父親生平的電影，該電影預計在2006年下半年殺青。We find the decay rate of 7be in be is smaller than that in au. the change of decay rate ( 0. 71 + 0. 32 ) %, indicates that the environment can indeed alter the decay rate, and the electronic affinity is not the only factor affecting the decay rate, so that one has to take the structure of the host materials into account in explaining the change of the decay rate
本工作將反應p + 7li 7be + n產生的7be分別注入至預計電子親和勢相差較大的材料be和au中，測量7be在這兩種材料中的衰變率的變化，發現7be在be中的衰變率要小於在au中的衰變率，其相對變化為（ oOne of our acoustic component parts is already being supplied to worldwide motorola mobile phone factories after passing extensive and thorough motorola quality audit. our management and finished products meet the qs9000 iso9001 standard, assuring you of the best quality. we guarantee always on time delivery and friendly customer support

醫科學生可在中心內觀看教學錄影帶，使用互動光碟，在假人身上練習，並親身體驗電腦模擬假人對治療程序的反應。Directing effects in electophilic aromatic substitution. nucleophilic aromatic substitution. strategies in the synthesis of multisubstituted benzene derivatives
31親電性芳香取代的定位效應。親核性芳香取代反應。合成多取代苯衍生物的策略。Anti - igg antibody was immobilized onto the surface of gold electrode modified with a thin layer of protein a. biotin labeled anti - igg antibody and hrp - streptavidin were premixed to form network complex to be used as probes for amplifying the sensing response of antibody - antigen interaction
抗體通過單層蛋白a固定到金電極表面，預先處理好的生物素化抗體和辣根過氧化物酶（ hrp ）標記的親和素形成的網狀復合物作為免疫反應信號的放大探針。The aromatic electrophilic substitution reaction was studied using nmr for the first time. on the base of substituents effects on the benzene, the orientation effect and reactivity was analysised quantitatively. this method may mostly predict the aromatic electrophilic substitution reaction
首次採用nmr研究芳基親電取代反應.依據取代基對苯的影響，定量分析了定位效應和反應活性.此法對芳基親電取代反應有一定的預見性Because the reaction initiated by the attachment of an electrophile, the process is called an electrophilic addition reaction.
因為反應是由親電試劑的附加而開始的，所以這個過程叫做親電加成反應。Because the reaction is initiated by the attachment of an electrophile, the process is called an electrophilic addition reaction.
因為反應是由親電試劑的附加而開始的，所以這個過程叫做親電加成反應。Silylate - terminated polyurethanes with built - in hydrophilic sites were synthesized. when the polymer is dispersed in water, the silane alkoxy end - groups of the polymer undergo hydrolysis, followed by condensation to form a stable cross - linked aqueous dispersion. tem studies indicated that with more incorporation of hydrophilic sites, the particle size of the dispersion decreased. it was also found that the film property depended on the particle size when the crosslinking density in particels was much higher. the average molecular weight of the elastically effective network chain mc measured by swelling experiments shows fairly good agreement with the theoretical value of mc. it was also found that the cross - linking density of the casting film may increase during the film formation and drying process
將硅氧烷封端的含親水基團的線性聚氨酯預聚體分散於水中，獲得穩定的聚氨酯分散體.由於硅氧基團水解、縮合，在分散體粒子內產生擴鏈交聯反應，生成了交聯水基聚氨酯分散體.透射電子顯微鏡研究表明分散體粒徑小、分佈寬.掃描電子顯微鏡研究了成膜結構及成膜性能與粒徑的關系.溶脹實驗計算獲得的兩交聯點之間的平均分子量與理論平均分子量相符.研究還發現此分散體膜在乾燥過程中可進一步交聯.膜的水溶脹及機械性能表明，此分散體具有極大的工業應用價值分享友人
