序列性

In this paper, we study the convergences and the growth of bi-random Dirichlet series by the strong law of large number s for independent and non-equally distributed random variables, and obtain some new result.

Bamboo mosaic virus encodes a 155-kDa replicase that the middle region contains a helicase-like domain according to the existence of several conserved featured motifs of helicase. Previous studies showed that the helicase-like domain exhibits both ATPase and RNA 5'-triphosphotase activities, and Mg2+ is essential for both activities. Mutagenesis of conserved motifs showed these amino acids play important roles for enzymatic activities. These results suggested that the properties of this denatured and renatured protein are coincident with other SF1 helicases.

从胺基酸序列分析显示，竹嵌纹病毒复制酵素中间区域的类解螺旋酵素具有解螺旋酵素的保留性胺基酸区域，经实验显示此蛋白具有ATPase和RNA 5'-triphosphatase活性，而且是依赖镁离子进行反应的，其中保留性胺基酸的突变会破坏其催化能力，说明这在大肠杆菌表达的蛋白质经过变性及重新摺叠的过程，具有和其他SF 1解螺旋酵素相似的特性。

The homology of the nucleotide sequences and genetic variation analysis of NDV strains suggested that mere were obvious divergence in gene lever among NDV vaccine strains and epizootic strains isolated from different areas and different ages.The divergence may have effect on amino acid and structure and function of protein in some extent and lead to difference of immunogenicity ,which was one of reason being difficult in preventing from ND.

通过对NDV F基因核苷酸序列同源性比较及遗传变异分析发现：我国不同年代、不同地区分离的NDV毒株与疫苗毒株之间在基因水平上存在较大差异，这种差异对氨基酸及蛋白质的结构和功能可能会有一定影响，而NDVF蛋白的差异同时也造成免疫原性的差异，这很可能是新城疫的免疫防治十分困难的原因之一。

We obtained a 1.5Kb DNA fragment of the succinate dehydrogenase flavoprotein subunit by PCR amplification and carried out the homolog analysis with those of other organisms.The result indicated a high homologh in this fragment among the five organisms.

通过PCR方法得到了琥珀酸脱氢酶黄素蛋白基因的一个1.5KB大小的DNA片段，并与其它生物的同种酶的基因序列进行了同源性分析，发现在所比较的五种不同生物之间这个区段具有很高的同源性。

The generalized spectral density and its derivative can be used to capture various specific aspects of serial dependence.

广义谱密度和它的导数还可以被用来检验序列相依的各个方面，例如鞅差，条件同方差性，条件对称性，和条件等峰度性等。

This dissertation is deals with study some of the specific linearity tests and investigate the possibility to find a specific linearity test that can use to accurately determinant the alternative nonlinear model and avoiding chose alternative nonlinear model other than the true DGP series generating from, in the case of rejecting the null model.

本文主要研究非线性时间序列模型的一些特定线性性检验问题，通过对研究文献的回顾与综述，研究者试图回答：为什么研究者倾向于使用非线性时序模型？为什么要进行非线性时序模型的线性性检验，并以此作为本研究的逻辑引导。

Based on systematic structural interpretation with 3D seismic data and analysis on regional geology and drilling data, the fault system and tectonic style of the Yitong Graben are studied.

通过对三维地震资料进行系统的构造解析，结合区域地质和钻井资料的分析表明，伊通地堑的断层系统在平面上主要由近东西向的张性正断层和北东走向的张剪性断层组成，反映盆地具右旋走滑的应力体制；断层在演化序列上分为4个类型，与盆地的形成和演化之间存在良好的对应关系。

They shared the highest homology to "world-B" group isolates in Brassica pathotype (between 91.8% and 100%). Phylogenetic analysis based on the CP gene sequences of TuMV strains or isolates showed that these 6 TuMV isolates from Shandong belonged to "world-B" group.

所得6个分离物的CP基因的核苷酸序列同源性较高，在97.0%～99.4%之间，系统进化分析表明：它们与Brassica致病型分离物中的world-B组分离物的同源性最高（91.8%～100%），亲缘关系最近，从而从分子水平上将TuMV山东分离物划分为world-B组。

The results presented could be regarded as the development of the previ-ous research on fuzzy matrix.And the convergence problem is basically resolvedfor lattice matrix applying to the fields of nerve network.

本文建立的有关结果可以视为对以往关于模糊矩阵幂序列的收敛性的研究成果的发展，为格矩阵应用于神经网络等领域解决了收敛性问题。

In our study,two important lepidopteron pests,beet armyworm and cotton bollworm were surveyed for their endogenous piggyBac.As a result,endogenous piggyBac elements were found in these two insects,and one of the piggyBac elements isolated from the genome of cotton bollworm was intact and thought to be potentially active.1 Clonging and sequence analysis of piggyBac from beet armywormUsing PCR technique,with degenerate primers,a DNA fragment of piggyBac-like element was cloned from the genome of beet armyworm,spodoptera exigua hubner.The DNA fragment was 456bp in length,and the deduced amino acid sequence shares 50%- 78% similarity with other piggyBac elements from insects.But one stop code was found in this DNA fragment.

由于转座子很难用常规的RT-PCR和RACE技术进行克隆鉴定，故本研究在兼并引物PCR的基础上，利用inverse PCR和vectorret PCR技术，不仅调查了鳞翅目两种重要的农业害虫甜菜夜蛾和棉铃虫的內源piggyBac存在情况，同时克隆到了內源性的piggyBac转座子，并且从棉铃虫中获得了一个结构完整、具有潜在活性的piggyBac转座子HaPLE1.1甜菜夜蛾piggyBac转座子基因的克隆与序列分析采用PCR技术，利用兼并引物，从甜菜夜蛾基因组中克隆出一个內源性piggyBac类似因子的DNA片段，并命名为SePLE。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
