合成体系 meaning in English
synthetic system
Examples
- Studies on thermodynamic analysis for synthesis of dimethyl carbonate
标准态下碳酸二甲酯合成体系热力学分析 - In other way , pea23 copolymer have small fluidity losing because lengh of side - chain was long and static electric repulsion was strengthen . if side - chain was too long , the static electric repulsion was strong , but the effect of dispersion of pc would reduce
因此，对于本论文的合成体系的pea的聚合度n二23为佳。而pc23系列减水剂中， n值在0 . 082一0 . 085之间的减水剂表现出来的净浆性能较好。 - We choose three classical representative polymers : polystyrene , mc nylon6 , and poly ethylene terephthalate ( pet ) to investigate what the effect of mesoporous molecular sieves on the procedure of polymerization of styrene ; the mechanical property of mc nylon6 and the crystallization process of pet
我们选取了具有代表性的聚苯乙烯、浇铸尼龙6 、聚对苯二甲酸乙二酯( pet )三种聚合物为切入点研究介孔分子筛mcm - 41对聚合物合成体系、加工性能及结晶行为的影响。 - Objective : construct high - level expression system of echistatin in e . coli methods : obtain amino - acid sequence of echistatin from genebank database . considering the bias of usage of 61 available aminoacid codons in e . coli , design the coding sequence of echistatin , synthesize the dna sequence chemically , get single copy coding gene and repeated two copy coding gene of echistatin . insert the sequence into expression vector pbv220 , and more , we construct fusion expression clone of echistatin with pcr , identify the recombinant vector by dna sequencing
目的构建蛇毒锯鳞蝰素( echistatin )的原核高效表达体系方法由genebank数据库检索蛇毒锯鳞蝰素( echistatin )的氨基酸序列，结合大肠杆菌蛋白质合成体系对氨基酸密码子使用的偏爱性，设计了echistatin编码基因，体外人工合成编码基因dna片段，通过适当的限制性内切酶位点插入表达载体pbv220 ，分别构建了echistatin的单拷贝表达克隆、双拷贝串联表达克隆；进一步通过pcr技术构建echistatin的融合表达基因克隆。
