| 1. | These three proteins contain two common clif domains , ubox and arm repeats . ubox is putative domain of dimeration of arc1 protein or the binding domain of next element
这种ubox结构均位于氨基酸序列的中间区域，这个区域有可能是蛋白质发生二聚化的区域或下一级组分的结合的位点。 |
| 2. | In the third chapter , the effects on the properties of ground state of spin = 1 anti - ferromagnetic single chain , from dimerization , exchange anisotropy and single - ion anisotropy , are investigated
第三章中，我们研究二聚化、交换各向异性j _ z 、和单离子各向异性d对一维自旋s = 1的反铁磁单链基态性质的影响。 |
| 3. | The method and some simple and important results are presented . in the second chapter , we study the ground state energy gap and the spin - peierls phase transition in the quasi one - dimensional spin = l / 2 dimerized anti - ferromagnetic single chain

| 4. | The results showed that the excitons were completely recombined after 900 fsec and the geometry structure of the polymer such as the bow and the ring - torsion angles returned to the ground states , which were the dimerization states
结果表明，大约在900fsec之后激子复合过程结束，电子结构返回到二聚化状态，体系的键序波、芳环扭角等回到基态的二聚化状态。 |
| 5. | Gfral is an extracellular protein that is attached to the outer cell membrane by gpi - anchor and could not transducted signalling directly . according to the original model , a gdnf dimer first binds to either monomeric or dimeric gfral , and the gdnf - gfral complex then interacts with two ret molecules , thereby inducing their homodimerization and tyrosine autophosphorylation
传统观点认为： gdnf首先与gfr 1结合形成gdnf - gfr 1复合物，此复合物再与ret结合形成三聚体复合物，引起ret的二聚化，并引起酪氨酸残基自磷酸化，从而引起下游的信号转导。 |
| 6. | The cyst cells enclosing spermatomeres maybe synthesize a kind of scf - like protein , which can recognize specially the c - kit receptor on the cellular membrane of spermatomeres . then c - kit is activated , dimerizing and autophosphorylating . at the same time , the tyrosine kinase domain of c - kit is activized , which phosphorylates the proteins that have sh2 domain
精母细胞周围的囊细胞可能合成scf样蛋白，特异地识别精母细胞膜上的c - kit受体，并刺激c - kit发生二聚化、自体磷酸化，激活胞内酪氨酸激酶活性，活化具有“ sh _ 2结构域”的靶蛋白，可能通过一系列信号级联，最终激活与减数分裂的相关蛋白或基因。 |
| 7. | The so made silica gel glass has quasi - inkbottle shape and median pore size distribution of 5 - 8nm which is suitable for the doping and protection of mpc molecules . mpc molecules in matrix always have a strong tendency to dimerization that can badly affect the linear absorption spectrum , causing quench of dye fluorescence and change the yield of photochemical processes . it is a vital problem that worth more attention
鉴于酞普的二聚化是影响其非线性性能和光限幅效应的重要因素，应用紫外一可见吸收光谱( uv / vis )测试技术，跟踪研究了复合体系在溶胶一凝胶转变过程中酞蓄二聚化的产生机理、主要影响因素和变化规律，提出了可能有效抑制二聚的技术途径。 |
| 8. | Ngf binding to trka receptors results in receptor dimerization and kinase activation . recent evidence supports that not all extracellular subdomains are responsible for receptor activation . structure based drug design for neurotrophic agonists with small molecular weight relies on knowledge of the interaction of neurotrophin with their receptors
Trka在ngf作用下发生二聚化，使胞内域中酪氨酸激酶区激活，从而使trka中酪氨酸自磷酸化，并进一步激活胞内信号转导通路，从而实现神经营养信号传递。 |
| 9. | But in the moderate electric field 150 kv / cm , there is a sharp change in the configuration and charge distribution of the exciton , i . e . the exciton is directly split into an electron polaron and a hole polaron . the polarization and dissociation happen at a same time , which differs from that in conjugated polymers . and in the strong electric field 350 kv / cm , appear structural phase transition of the chain and luminescence quenching
同时得到两个重要的临界电场值： 1激子解离电场ec1 （ 150kv / cm ） ，在此电场下激子发生瞬间解离，成为电子型极化子和空穴型极化子； 2结构相变电场ec2 （ 350kv / cm ） ，在ec2下二聚化晶格开始被等距晶格取代， ptcl络合物链发生结构相变，并伴随peierls能隙渐趋消失和发光猝灭的现象出现。 |
