轉羥甲 的英文怎麼說
中文拼音 [zhuǎnqiǎngjiǎ]
轉羥甲
英文
transhydroxymethylase-
Aminated and hydroxylated polysulfone membranes were prepared by amination and hydroxylation reaction, respectively. then bovine albumin ( bsa ) - fixed membranes were obtained by crossed - linking albumin into porous membrane with 1, 1 ' - carbonyldiimidazole and bisoxirane reagents, respectively. a mathematical model for facilitated transport in asymmetric membranes with fixed site carriers was derived by assuming an instantaneous, microscopic concentraion fluctuation in the membrane
以氯甲基聚碸為基材,通過相轉化法制備出具有底部貫通孔的非對稱膜,通過胺化和羥基化反應,分別制得胺化聚碸膜和羥基化聚碸膜,再採用羰基二咪唑和雙環氧烷兩種活化試劑對其進行活化,將牛血清白蛋白固載在膜內,獲得固定白蛋白促進傳遞膜。This dissertation focuses on how to develop a high performance damping mechanism based on multi - energy transitions, which is independent or little dependant with the viscoelasticity of polymer matrix. three sections are mainly included in this dissertation as follows : chlorinated polyethylene ( cpe ) / piezoelectric ceramic ( pzt ) / vapor grown carbon fiber ( vgcf ) composites ; cpe / 2, 2 ' - methylene - bis - ( 4 - methyl - 6 - cyclohexylphenol ) ( zkf ) / vgcf composites ; organic hybrids made from cpe and small molecules cpe / pzt / vgcf composites : the damping composites of multi - energy transitions mechanism were produced by mixing pzt and vgcf into cpe. in this system, the mechanical vibration energy that was transmitted to cpe was found to convert into joule ' s heat through conduction paths between vgcf in the polymer matrix, so the vibration fades away
本論文主要包括三個方面的研究內容: ?氯化聚乙烯( cpe ) /壓電陶瓷( pzt ) /氣相生長碳纖維( vgcf )復合材料; ? cpe /雙[ ( 2 -羥基- 3 -環己基- 5 -甲基) -苯基]甲烷( zkf ) / vgcf復合材料; ? cpe基有機小分子混雜型復合材料cpe / pzt / vgcf減振復合材料:利用壓電和導電填料填充高聚物基體,當復合材料受到機械振動時,通過高聚物基體將機械振動能傳遞到壓電陶瓷粒子上,利用壓電陶瓷的壓電效應,將機械能轉換成電能,則電流在導電粒子產生的迴路中流動,由於導電迴路具有一定的電阻,所以電能又轉變成熱能耗散掉,從而起到減振的目的。It was confirmed that the key enzyme of coq10 synthesis is p - hydroxybenzoate polyprenyltransferase, encoded by gene ubia in e. coli and lacks specificity to the aggregation length of its substrate ( polyisoprenyl pyrophosphate ). if gene ubia can be introduced into psb and is high expression in psb, a recombinant strain producing coq10 could be obtained. consequently, the productive cost will decrease sharply
業已證實coq _ ( 10 )生物合成的關鍵酶為對羥基苯甲酸聚異戊二烯焦磷酸轉移酶(在大腸桿菌中該酶由ubia基因編碼) ,該類酶對底物聚異戊二烯焦磷酸( ppp )的聚合長度並無特殊要求。
