  2. The authour investigate the dosing conditions and effect of the pac to the huanghe water - source, which includes the following four parts : the selection of the pac ; the confirmation of dosing scheme and effect of the pac ; the research of application of potassium permanganate in combination with pac ; the research of the pac ' s modification and the modified effectiveness. the experiment is mainly carried out on the pilot system in the jieyuan water plan of tianjin. the results of the reseach include the following : l ) the pac from zunhua plant is selected as the better carbon for the source water of tianjin through the experiment ; 2 ) through the pilot experiment we conclude that the pac ' s best adding point is the mixing tank and the better dose is 10mg / l, on which the codmn of filtered water can be decreased to 40 % and the effluent have no problem of odour and color ; 3the adsorbing experiment show that pac mainly adsorb the organic matters which molecular wt., distribution between 500 and 3000, and can adsorb organic matters whose molecular wt., distribution are bigger than 6000 if the dose of it is adequent ; 4 ) pac together with potassium permanganate can remove the organic matter more effectively than each of them alone, and reduce the rising trend of turbidity of the flotation ' s effluent due to adding pac ; 5 ) the thesis made a research on the surface properties and the adsorbing capability of the modified carbon by oxidizer : the modified carbon with 20 % h2o2 can remove more organic pollutants than the untreated one by 12 % when we add a higher dose of coagulant ; 6 ) the modification of reduction and loading metal ions are also sttldied, and drow the following conclusions : the modified carbon with 5 % ammonia can enhance the organic matter ' s removal effectiveness by 10 % to the tianjin source water than the untreated one, and the modified one with loading metal ion remove the organic matters from the tianjin source water better ( 8 % ) than the untreated one due to the strong affinity betwween the humic acid and copper ion

    本文的實驗主要是在天津芥園水廠的中試系統上完成的，論文的成果和結論主要包括： 1 ）通過靜態實驗選定河北遵化活性炭廠生產的煤質炭為適合天津原水的炭種； 2 ）中試實驗確定粉末活性炭的較佳投加點為混合池投加，較佳投加量為10mg l ，此時可使濾后水的cod _ （ mn ）降低40 ，且可較好地控制濾后水的嗅味和色度； 3 ）初步確定粉末活性炭對原水中有機物的吸附主要集中在分子量在500 - 3000范圍內，投量增大時可吸附部分分子量大於6000的有機物4 ）中試實驗表明：粉末活性炭與高錳酸鉀聯用可取得較兩者單獨應用時對有機物更好的去除效果，且對因投加粉末活性炭而造成的氣浮出水濁度升高有一定的改善作用； 5 ）研究並初步確定氧化改性對粉末活性炭表面性質和有機物的去除效果的影響：粉末活性炭的氧化改性會使其表面的酸性官能團大量增強，表面極性增加；經20的過氧化氫改性的活性炭在增大混凝劑投加量（ fecl _ 3投量為15mg l ）時對有機物的總體去除效果較原活性炭提高12 ， 1次氯酸鈉改性活性炭對有機物的去除效果較原活性炭提高6 ； 6 ）研究並初步確定還原改性、負載金屬離子對原水中有機物的去除效果的影響：經5氨水改性的活性炭可提高天津源水中有機物的去除率達到10 ；負載銅離子后的活性炭可提高對腐殖酸類物質的去除能力，一般可提高8左右。
  3. This strain ' s virulence was judged by mean death time of chick embryos ( mdt ), intracerebral pathogenicity index in day - old chicks ( icpi ) and intravenous pathogenicity index in 6 - week - old chickens ( ivpi ) and it was found to be the virulent strain. at last, it was tested by the recurrent infection and found that it was the newcastle disease virus ( ndv ), and it was named hbg - 1 strain. in order to find the difference of the cleavage site of this strain with f48e9 and ? 30 strain, a part of the cleavage site of fusion protein gene fragment was amplified by rt - pcr using a primer and sequenced. the sequence analysis showed this strain had low homology with f4ge9 and cso. a phylogenetic tree based on the published sequences of ndv reference strains was constructed and showed the isolated strain hbg - 1 belonged to the genotype w ndv, a novel genotype ndv

    為了進一步探尋分離株與標準株的異同，又採用rt - pcr方法，擴增獲得分離株f _ o裂解位點附近的基因片段，經測序后與國際上已發表的新城疫病毒的核酸序列進行比較，結果表明其與標準株和疫苗株之間的同源性較低，僅為82 86之間。經系統發育進化樹分析后，判定該分離株為新城疫病毒（ ndv ）基因型。運用計算機軟體對其裂解位點處的氨基酸序列進行預測和分析，結果表明該分離株為新城疫病毒強毒株並具有基因型的典型結構特徵。
  4. The main numerical method of this code is coming from scheme ( jameson, schimit and turkel ) : using cell - centered finite volume method as spatial discretization tools, and a system of ordinary differential equations for time variable is obtained, which is solved by utilizing five - step runge - kutta scheme as time marching method, introducing artificial dissipation to damp high frequency oscillations near the shock and stagnation point

    本論文採用歐拉方程作為控制方程，利用中心有限體積法進行空間離散，得到對時間變量的常微分方程組，採用龍格庫塔多步法進行時間積分，加入人工粘性以消除激波和駐點附近的壓力振蕩等方法來對naca0012翼型的實際流動進行并行數值模擬。
