Solid bearing pin type fv conveyor chains ; single - strand and double - strand chains not to be used for new designs Fv型整体轴承销式输送机链.单股和双股链不适用于新
Chapter fv expound liang " s thought on developing machinery industry , developing venture cooperation and trust 梁启超的发展机器大工业思想、发展股份制思想、呼唤托拉斯构成第四章的内容。
4 the - fv relation of gpe / eg , pe / gpe / eg nanocomposites and general composites accorded with conduct behavior described by p 4gpe尼g 、 pe / gpe尼g纳米复合和常规复合材料的a伙几关系符合逾渗理论描述的导电行为。
Fourth , the fv / fo , fv / fm , yield and photochemical quenching coefficient ( qp ) decreased whereas non - photochemical quenching coefficient ( qn ) increased under cold stress ( 4 )在低温环境中，光系统( ps )及其电子传递过程受到明显抑制。
Objective : to construct the single - chain fv gene of human anti - hbsag and to analyse the expression of the constructed gene in eukaryotic cell and prokaryotic cell 目的构建人抗hbsag单链抗体基因，在真核细胞和原核细胞中进行表达，并对其表达产物的活性进行鉴定。
Under high light treatment , the f ormation of a and z decreased , and the values of non - photochemical quenching ( npq ) and fv / fm in a29 were both lower than those in the wild - type plant 通过冻融法从该植株的类囊体中提取vde酶，其酶活性为3 2 ，是对照植株的45 7 ，表明vde酶受到了抑制。
H chain cdr3 region is thought to be the antigenic epitope of antibody of monoclonal antibody np30 . therefore , anti - id antibody vaccine and antigenic epitope vaccine are important strategy in developing schistosomajaponicum vaccine Fv基因，且其表达产物保留了抗体的亲和性和特异性，有可能替代杂交瘤细胞分泌的单克隆抗体np30作为免疫检测试剂。
Combined the above results , there existed significant correlation among chlorophyll a fluorescence parameters ( fv / fo , fv / fm , yield , qp , qn and mda contents , plasma membrane permeability in euonymus japonicus " zhuzi " seedlings 叶绿素荧光a参数与mda含量及质膜相对透性的的相关性分析表明，低温胁迫下， ps原初光能转化受抑制程度与膜脂过氧化存在一定的关系。
Thus , immunologists have sought smaller molecules with the antigen - recognition capability of antibodies . the variable domains of the heavy ( h ) and light ( l ) chains are sufficient for antigen recognition but the non - covalent complex of the two variable domains ( fv ) is unstable . it is possible to genetically engineer a single - chain fv ( scfv ) with the h chain v region connected to the l chain v region via a 15 amino acid linker composed of serine and glycine amino acid residues 二、日本血吸虫单克隆杭独特型抗体np30的单链狐（ scf ）的构建、表达及对balbic小鼠诱导保护性作用研究l 、日本血吸虫单克隆杭独特型抗体np0的单链抗体归cfv ）的构建、表达通过pcr方法体外扩增并经测序验证的重链、轻链可变区（ vh 、 vl ）基因先后重组入原核表达质粒ptha90相应的位点上，中间通过一连接肽（ gly在er ） 。
Combining the fuzzy decision - makin g theory with the analysis method of the interested degree in fault tree analysis , the ideas of ensuring the membership degree with the interested degree and establishing fuzzy matrix is put forward , and is testified with the stringent mathematic theory . therefore the efficiency and quantity of fuzzy matrix establishment is improved , and further the field of application of fault tree analysis is developed 将模糊决策原理和故障树分析中的重要度分析法相结合，提出用fv重要度确定隶属度，构造模糊矩阵的思想，并通过严格的数学理论加以证明，有效地提高了模糊矩阵构造质量和效率，进一步拓宽了故障树分析法的应用领域。
