Such as when the substrates was benzidine and a - naphthol, the absortion peak was 450nm after catalyticed by dna, and 501nm after catalyticed by pod, if changing substrate to benzidine and pyrocatechol, the absortion peak was 503nm after catalyticed by dna and 603nm after catalyticed by pod. the second difference was the different result after hplc : the result of hplc ( substrates : benzidine and a - naphthol ) showed that the products under the affect of dna and pod had different value on the peak and the area
然後對以聯苯胺與-萘酚為底物,以h _ 2o _ 2為氧化劑,進行高效液相色譜分析,分析結果表明dna與過氧化物酶作用后的產物在峰面積和峰高上有不同數值;同時,不同形式的dna對該反應都有催化活性,表明只要是生物來源的dna (非特異性dna )都具有一定程度的催化活性。The crystallization and melting behavior of mellocene - catalized branched and linear polyethylenes of low molecular weight was studied. it was found that the crystalline lattice of branched polyethylene is larger than that of linear polyethylene because of the existence of branched chains. the melting behavior of branched polyethylene is similar to that of linear polyethylene since the branched chains can not enter the lattice. however, the crystalline behavior of low molecular weight branched polyethylene is the same as that of high molecular weight linear polyethylene, but different with that of low molecular weigh linear polyethylene. kinetics theory analysis evidenced that the transition temperature of growth regime of the branched polyethylene is about 20 lower than that of linear polyethylene with the same molecular weight. it may be attributed to the existence of short branched chains
研究了金屬茂催化的低分子量支化聚乙烯和線性聚乙烯的結晶及熔融行為,發現支化聚乙烯的結構與線性聚乙烯相同為正交結構,但晶格略有膨脹.支鏈的存在對熔融行為影響不大,兩種聚乙烯的熔點均隨結晶溫度的升高而非線性增加,表現出低分子量樣品的共同特徵.但支鏈的存在對結晶行為卻有很大的影響,主要是由於支鏈的存在降低了晶體的結晶速率從而影響結晶過程,使得低分子量的支化聚乙烯的結晶行為與高分子量線性聚乙烯的結晶行為相似而與低分子量的線性聚乙烯不同.動力學分析表明,低分子量的支化聚乙烯的結晶生長方式的轉變溫度比同等分子量的線性聚乙烯降低了約20A non - equilibrium model was established to simulate the catalytic distillation process in the preparation of ethylbenzene from dry gas
摘要針對催化蒸餾法干氣制乙苯過程,建立非平衡級模型,並進行了計算機模擬。Recently, as an advanced and eco - friendly method of powder preparation, freeze - drying has been developing quickly. the ultrafine ni powder with the average size of 50nm was prepared by freeze - drying form the niso4 and naoh and was studied by means of xrd, ir, fesem, tem, and dsc. the catalysis of nickel powders to nh4clo4 and how the precursor forms and the processes of the amorphous precursor to the final nickel powders are discussed
本論文以分析純niso4 、 naoh為原料,採用冷凍乾燥技術成功的制備了50nm左右的球狀超細鎳粉,通過xrd 、 ir 、 fesem 、 tem 、 dsc等材料現代分析手段對產物進行了分析和表徵,研究了超細鎳粉對高氯酸銨熱分解的催化活性、前驅體的形成以及非晶態金屬鹽到晶態超細鎳粉的轉變過程。Abstract : the objective, characteristic and application of the nonlinear control strategy are introduced. how to apply and implement the function of the controller, how to start and stop the control strategy and trouble shooting is discussed. result of commissioning show that the application of nonlinear level control strategy in rfcc of qianguo oil refinery was successful
文摘:簡要介紹了非線性液位控制策略的目的、特性、應用,並著重介紹非線性液位控制系統實施過程和控制器功能,控制器的投運和控制器的故障處理,由投用效果看出非線性液位控制系統在前郭煉油廠重油催化裂化裝置得到了很成功的應用。It clearly allows us to engineer enzymes with novel functions and features by strategies, such as error - prone pcr, dna shuffling and stagger extension process ( step ), when very little is known about spatial configuration of proteins. therefore millions of years in nature can in principle be accomplished in the test within several years. according to the basic idea of directed evolution, we modified the a - aldc gene by error - prone pcr
它不需要事先了解酶的空間結構和催化機制,而通過在體外模擬自然進化機制(隨機突變,重組和自然選擇) ,利用易錯pcr , dna改組,交錯延伸等方法,改造酶基因,定向選擇(或篩選)有價值的非天然酶,短期內在試管中完成在自然界需要幾百萬年的進化過程。All the results show that the fundamental waves play a role of " catalyzer " in these nonlinear interactions
研究表明,非線性過程中基波起「催化劑」作用。At lower growth temperature, the lower extracting rate of carbon atoms from catalyst particles due to the lower activity of the catalysts resulted in more defects formed in carbon nanotubes. moreover, the lower transportation rate of carbon atoms in catalyst particles also made lots of carbon atoms deposited on the surfaces of grown carbon nanotubes, or on carbon wrapped catalyst particles, even to form amorphous carbon layers
在較低溫度時,由於催化劑的活性較低,導致石墨面在生長過程中引入的缺陷較多;另一方面,碳原子在催化劑顆粒內遷移速率較低,使得多餘的游離態碳原子(或原子團)可能在納米碳管表面以非晶形式沉積,或者包覆催化劑使其「中毒」失去催化活性,或者直接形成非晶的碳納米顆粒。分享友人
