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。The one of most important factor of affecting durabilities in construction concrete is chloride deterioration. the chloride penetration current exceeds 2, 000 coulomb in the no mineral admixtures silicate cement, using 30 % ~ 40 % fly ash it falls to 800 coulomb and the 60 % micro - slag falls to 500 coulomb ; though silica fume reduces penetration current, it deteriorates the workability of concrete
氯離子侵蝕是影響混凝土結構安全性最重要因素之一，不摻加任何礦物摻合料，氯離子滲透電量一般大於2000庫侖；粉煤灰摻量在30 40 ，滲透電量達到800庫侖；礦粉摻量在60左右，滲透電量達到500庫侖，並具有較高的綜合性能；硅灰可以改善混凝土氯離子滲透能力，但惡化了混凝土工作性。The mechanism is that the introduced complementary oligonucleotides can bind to the corresponding mrna or double - stranded dna in genome and form partial double - stranded molecules or triple - stranded nucleic acid molecules by sequence - specific and nonsequence - specific antisense action, thus the target gene will be orientationally blocked and expression of the target inhibited so that therapeutic effect could be attained. in this study, we designed a fragment of human c ii ta cdna in antisense orientation using mrna of c ii ta as template. the primers were designed based on 94 - 500 nucleotides segment in 5 " end of ciita gene so that the interested gene contained 407 base pairs which included two aug codons in 1 16 and 188 nucleotides as well as the splicing site between the first and the second exons
本研究設計以c tamrna為模板的反義cdna片段，從c ta基因5 』端第94位到500位核苷酸段設計引物，目的片段407bp ，覆蓋第116和188位兩個aug密碼子，也包含了第一外顯子和第二外顯子間的剪接位點：用常規分子生物學方法構建了反義片段的腺病毒表達載體（ padeasy - 1系統） ；腺病毒載體經hek293細胞包裝產生含反義片段的重組腺病毒，用氯化銫密度梯度離心法獲得純化的高滴度腺病毒；進行體外基因轉移，分別用反義片段真核表達載體轉染p388d1細胞和用重組腺病毒感染hela細胞，觀察導入的c ta基因反義rna抑制細胞內組成型或誘導型c ta基因表達的作用，從而達到調控mhc -類分子表達的目的。Fifthly, based the established model of chloride induced rebar initiation corrosion time and the model of concrete cover cracking time due to corrosion products volume expanding, a probability based model is established for service life predicting of reinforced concrete structure in chloride environment. the prediction model regard corrosion induced concrete cover cracking matching the cracking limitation as durable limit state, or as termination of the component service life
第五，根據已建立的氯離子侵入混凝土導致鋼筋初銹的時間計算模型和混凝土中鋼筋銹蝕膨脹導致混凝土保護層開裂的時間計算模型，以保護層因銹蝕脹裂，裂縫寬度達到寬度限制值為耐久性極限狀態，建立基於概率極限狀態分析方法的構件耐久壽命預測方法。The positive transformants with the integrates mn - sod gene was identified by zeocin - resistance, pcr screening and expression in p. pastoris. the recombinant mn - sod protein was successfully expressed in pichia pastoris based on the evidences that a relative molecular weight about 23kd appeard in sds - page, the obvious activity of sod existed in native - page and enzymatic activity test, and mn - sod activity was specific base on the inhibition with the mixture of chloroform - enthanol ( 3 : 5 / v : v ) and potassium cyanide. two secreted plasmids ppiczaa - sodm18 and ppiczaa - sodc were constructed and after there linearization were transferred into chromosome of pichia pastoris gs115 by electroporation
Pcr鑒定及mut表型分析進一步說明，目標基因已經重組到宿主菌基因組染色體上； 0 . 5甲醇誘導表達后， sds - page結果顯示，表達的蛋白相對分子量約為23kd ，活性電泳出現明顯活性條帶；酶活性測定顯示，重組菌株sod活性比對照提高5倍左右；氯仿-乙醇（ 3 : 5 v : v ）和kcn （ 5mmol l ）抑制反應進一步證明，所表達的sod為錳超氧化物歧化酶。分享友人
