Based on band types of Per.Est.and soluble protein,the authors caculated their genetic similar coefficient and genetic distance by using the formula of Forguson and Aquado ＆ Avise.

根据其中的PER、EST和可溶性蛋白谱带的分布特征，用Forguson和Aquado＆Avise的公式分别计算其谱带的相似性系数和遗传距离，以类平均法进行了聚类分析。

According to the porportion of restriction fragments shared,the genetic distancesamong the 4 populations were calculated with popgene3.2,and a cladogram wasproduced with MEGA3.1.The result showed that the genetic variance dismatch withtheir diapause variance.

根据限制性片段共享度，利用POPGEN3.2计算4个群体的遗似距离，并利用MEGA3.1进行聚类分析，结果表明其遗传变异与其滞育变异的特征不相符。

This paper summarized the structure and function of the ERF transcription factors in cotton and other plants, and discussed the significance in enhancing cotton disease resistance and molecular genetic improvement based on the current research progress.

本文主要论述了棉花等植物中ERF的结构与功能特征，当前相关研究进展，及其对棉花抗病性分子遗传改良的意义。

Numerical analysis indicated that B2817 was a species of genus Vibrio and shared a high homology with V. gazogenes. However, there were obvious differences between them in phenotypic and chemotaxonomic characterization. The result from this study indicates that B2817 is probably a novel species of Vibrio.

经多相分类学鉴定，发现B2817是弧菌属中一个种，与弧菌属中的产气弧菌Vibrio gazogenes亲缘关系最近，但两者在形态、生理生化特征、分子遗传等方面存在很大差异，故认为B2817可能是弧菌属的一株未被认识的新种。

Were analysed,they had :(1)intra-uterine asphyxia with Apgar scores of 8～10 at birth,(2)with neurological symptoms on the first day after birth,(3)diseases of infection,genetics and metabolism,and deformity were ruled out,(4)with characteristic findings of HIE o...

其诊断符合以下条件：(1)有宫内缺氧史，出生Apgar评分 8～ 10分；(2 )生后早期出现神经症状；(3)排除感染、遗传代谢及畸形等神经系统疾病；(4)头颅B超或CT有HIE特征性改变。

Then, the behavior properties of synthetic musks as POPs were analyzed on the basis of their biological accumulation, environmental degradation and biological transformation. Some visible adverse ecological effects including environmental hormone toxicity, genetic toxic effects, and physiological ecotoxicity of synthetic musks, and their influences on enzymatic activity, and their toxic effects on microorganisms were also summarized.

在此基础上，从人工合成麝香的生物蓄积行为、环境降解行为和生物转化行为等3个方面，对人工合成麝香所具有的持久性有机污染物的行为特征进行了分析；概述了人工合成麝香的环境激素毒性、遗传毒性效应、生理生态毒性、对酶活性的影响以及对微生物毒性效应的研究进展，展示了人工合成麝香所可能产生的不良生态效应。

Their genetic variation among species and prove- nances were discussed.

球果和种子受遗传控制较强的特征，最具有区分和比较的意义。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
