The mRNA of pituitary glands from seven important economic Pleuronectiformes fishes was extracted,the cDNA sequences of GH gene were then isolated from Cleisthenes herzensteini,Limanda yokohamae,Pleuronichthys Cornutus,Cynoglossus robustus,Platichthys bicoloratus, Zebrias zebra and Paralichthys dentatus with RT-PCR method by using designed specific primers based on the reported GH cDNA sequences of Pleuronectiformes. The results of sequencing showed that lengths of the above cDNAs are as follows: 479 bp,564 bp,519 bp,440 bp,564 bp,440 bp and 522 bp.The GH cDNA sequences encode mature polypeptide of about 140 to 170 amino acid.The full-length growth hormone cDNAs of Paralichthys lethostigma and Scophthalmus maximus were cloned by Switching Mechanism At 5\' end of the RNA Transcript RACE technology.

从7种重要鲽形目经济鱼类——高眼鲽、黄盖鲽、木叶鲽、宽体舌鳎、石鲽和条鳎、夏鲆的脑垂体中提取mRNA，并采用RT-PCR方法，根据已克隆得到的鲆鲽鱼类生长激素基因的保守性序列设计特异性引物，克隆了含开放阅读框的生长激素(Growth Hormone，GH)cDNA序列，测序结果显示，高眼鲽、黄盖鲽、木叶鲽、宽体舌鳎、石鲽、条鳎和夏鲆的GH cDNA长度依次为479 bp、564 bp、519 bp、440 bp、564 bp、440 bp和522 bp，编码140-170个氨基酸的成熟GH多肽片段；从漠斑牙鲆和大菱鲆脑垂体中提取mRNA，利用SMART-RACE技术建立脑垂体cDNA文库，并从该文库中克隆出大菱鲆和漠斑牙鲆生长激素基因cDNA全长序列。

In this paper, concepts of grey absolute relation coefficient and grey relative relation coefficient are proposed. And a computational formula of grey relation grade is developed, which formes a new theoretical model for analysis of grey relation.

1引言灰色关联分析是灰色系统理论的一个重要内容，它通过参考序列与比较序列各点之间的距离分析来确定各序列之间的差异性和相近性，从而找出各因子之间的影响关系及影响系统行为的主要因子。

It is analyzed which is the characteristics of time series , the research tool and the eigenfunction of time series. ARIMA model system is analyzed and discussed.

介绍了时间序列及其相关的基本概念，分析了随机时间序列的特性、研究中的方法性工具以及时间序列的特征函数，分析并讨论了ARIMA模型体系。

A 1.2 kb fragment of the gyrB gene of 17 Gordonia strains including type strains were determined by direct sequencing of PCR amplified fragments. Total 25 strains (8 were retrieved from public database) of genus Gordonia form a distinct phyletic line in the gyrB-based tree and are separated from other closely-related species of genera to suborder Corynebacterineae.

在Gordonia菌种间之差异研究中则发现12种Gordonia gyrB基因序列相似度介於79.3%-97.2%，16S rDNA的序列相似度为96.2%-99.7%，可知Gordonia放线菌的16S rDNA保留性极高，较难利用此基因序列进行菌种间之区分。gyrB基因之变异程度无论是在菌属，菌种甚至各分离株间均较16S rRNA基因大。

Blasting in the GenBank, 16 of them were found that they have no significant similarity with data in GenBank, which means they were new sequences, but one sample(020) of them has high homology with data of Glyceraldehyde 3-phosphate dehydrogenase genes of other species in GenBank.

在GenBank中做Blast检索后，发现其中16条与数据库中序列无明显同源性，为新序列；一条序列(编号020)与数据库中其他物种的3-磷酸甘油醛脱氢酶基因高度同源。

Methods The total RNA of leucocyte was extracted 43 allergic vasculitis patients and 24 normal subjects before and after treatment with Trizol reagent and the integrity and concentrations of HLA-DRw53 gene mRNA were determined by agarose gel electrophoresis and UV spectrophotometer after denatured with 1% formaldehyde, the product was transcribed into complementary retroviral synthetic deoxyribonucleic acid, and sequence-specific primers were designed based on the sequences of second HLA-DRw53 gene exon and housekeeping gene glyceraldehyde phosphate-dehydrogenase cDNA.

OPJ16-759 shows 83% to 100% identity with 14 EST sequences from abiotic stressed leaves of Vitis vinifera var. Chardonnay, 94% to 100% identity with 3 EST sequences from water stressed berry of Vitis vinifera var. Cabsau.

OPJ16-759与欧洲葡萄&霞多丽&叶片14条非生物胁迫EST序列有83 ~ 100%的同源性，与欧洲葡萄&Cabsau&浆果3条水分胁迫的EST序列有94 ~ 100%的同源性。

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。
