peak induction 中文意思是什麼
peak induction
解釋
陡化感應-
Increasing ultrasound intensity in the range of cavitation threshold and cavitation peak value, decreasing monomer concentration and increasing the temperature make the induction period shorter. under optimized reaction conditions, the conversion of ba can reach 90 % in 11 min at high n2 flow rate the viscosity average molecular weight of the obtained pba reaches 5. 24 106. the molecular weight of pba varies with ultrasonic irradiation time, indicating that the ultrasonic induced emulsion polymerization is dynamic and quite complicated, polymerization of monomer as well as degradation of polymer occurs concomitantly
一、實現了無常規化學引發劑存在下的超聲輻照引發丙烯酸正丁酯（ ba ）間歇乳液聚合，制備了pba納米粒子，在11min內轉化率達到90 ，分子量達5 . 24 10 ~ 6 ，隨反應時間的延長而降低，表明超聲輻照引發乳液聚合是一個動態的復雜過程，單體的聚合和聚合物的降解同時發生。 -
The expression conditions of e2 gene in p. pastoris were optimized, the results indicated that the peak obtained after 72 hours ; pattern of inhibition / induction could improve expression level ; the best ph value were between 7. 5 and 8. 0 and the optimized methanol - induced concentration was 2 % - 3 % the e2 genes of the prevalent strain ( guangxi yulin strain ) and c strain derived from rabbit spleen tissue were amplified and cloned into e. coli the expression vector pproex - htb respectively, the recombinant plasmids pproex - gxyl and pproex - c were obtained and then were transformed into the dh5a e. coli competent bacteria respectively, the recombinant bacteria could express the major antigen region of e2 gene, the expression yields amount to 35 % and 38 % repectively
豬瘟病毒ez基因的原核表達： pcr擴增出當前豬瘟流行野毒株，中國豬瘟兔化弱毒（ c株）兔脾組織毒ez基因的主要抗原區，將其克隆到原核大腸桿菌表達載體pproex htb中誘導表達，經sds page檢測表明，重組質粒能表達ez基因主要區蛋白， westernblot檢測表明，誘導表達蛋白與豬瘟陽性血清發生特異性反應，表達量為35和38 ，可用於基因工程診斷抗原。
