中文拼音 [běnànshǔ]
苯胺數
英文
aniline equivalent-
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。With phosphato - tungstic acid as catalyst and phosphoric acid as dehydrant, n - phenylmaleimide was prepared from aniline and maleic anhydride by two - step method. the yield was 88. 7 % and the purity was 98. 2 %
以順酐和苯胺為原料,磷鎢酸作催化劑,磷酸作脫水劑,採用兩步法制得n -苯基馬來酰亞胺,得到最佳反應工藝條件,產品收率為88 . 7 % ,純度為98 . 2 % (質量分數) 。We made use of wheatstone bridge to control ratio of heating power between the samples, thus, it enable to control and measure the differential heating power accurately. consequently, it improves sensitivity of the system. the resolution of the measurement can reach from 1 : 1000 to 1 : 10000 or better in comparison with the traditional differential technique
我們測量了聚苯胺及其摻雜鹽酸后在1 . 8k至45k的熱容,利用聲子分形子模型來處理非晶態對比熱的貢獻,對獲得的數據進行處理,發現eb和es的比熱數據均不符合德拜理論,超出德拜模型的比熱來源於非晶態的貢獻。So we figured that the influence of the electron - electron interactions must be considered in our work. added an electron - electron interaction ( up to the fourth neighbor ) term to the baranowski - buttner - voit ( bbv ) model for polyaniline, we carried out a self - consistent - variation calculation for an biexciton in the pernigranlilne - base polymer, in order to confirm the model hamiltonian. the results showed that two peaks ( near l. oev and 1. 5ev ) appeared in the calculated optical absorption, besides the reproduced electronic structure, bond order wave ( bow ) and ring - torsion angles
發現引入電子?電子相互作用后,聚苯胺靜態激子的性質受到影響,該聚合物的鍵序波、芳環扭角和電子中文摘要結構發生了變化,而且在理論吸收譜的低能端出現了明顯的二特徵吸收峰( 1 . 0ev和1 . 5ev附近) ,這一結果與實驗數據很好的吻合,從而這一點表明我們所考慮的因素是合理的。Studies on microwave absorbing material of doped polyaniline
摻雜聚苯胺復合材料電磁參數及吸波性能研究The dielectric constant of pani - mmt nanocomposite was increased 5. 5 times that of pani and 2. 7 times that of mmt, besides, the conductivity of pani - mmt particle was increased about 10 times that of pani at 1000 hz and 20. meanwhile, the dielectric loss tangent can also be increased about 1. 7 times that of pani
在1000hz 、 20時,其介電常數比蒙脫土提高了約2 . 0倍,比聚鄰苯二胺提高了近4 . 3倍,同時介電損耗也有一定的提高。Organic - inorganic nanocomposite, which are the complex of inorganic nanopraticles with organic compound, is a popular study subject in nanoscale composite. the nanocomposite can not only take advantage of several advantage, but also produce new properties. in this thesis, taking account of the problems in electrorheological fluids such as high leakage current, low yield stress and stability, the pan - batio3 nanocomposite with different structure are prepared by in - situ complex technology and modified sol - gel method
根據目前電流變液中出現的問題(如屈服應力不夠高,漏電流密度不夠低,穩定性不夠好等問題) ,基於聚苯胺有較高的熱穩定性,且密度又小,特別是聚苯胺的介電常數和電導率均可按需調整,此外,鈦酸鋇無機納米粒子作為一種無機鐵電體,在電場作用下具有自發極化的能力,一方面可以為體系提供高的介電常數,另一方面又可保證體系的絕緣性能。Estimation of the acute toxicity of chloro - aniline compound to photobacterium phosphoreum by using topological index
拓撲指數估算氯苯胺類化合物對發光細菌毒性Our work shows that the extended bbv model can reproduce most observed data of the polymer. more works can be done on the other oxide forms of polyaniline. and the method can be generalized to other quasi - one dimensional systems
我們的工作表明,擴展的bbv模型能再現聚苯胺體系的大量實驗數據,可以對聚苯胺的各種氧化態作進一步研究,也可以推廣到其他的類聚苯胺的準一維體系中去。分享友人
