石油烃含量在3g/kg土和6g/kg土2个处理中，连翘的生理指标和叶绿素荧光参数的变化幅度要小于大花水桠木和紫穗槐，对石油烃胁迫的抗性更强；石油烃含量在12g/kg土时，3种植物的生长均受到最大抑制。

He thyrotropin-releasing hormone is a bioactive peptides Synthesized and excreted from hypoghaiamus. It is the mainphysiological action that stimulates the Synthesis of antehypophysis, release of thyroid-stimulating hormone and excretion of prolactin.

RH是由下丘脑合成和分泌的活性肽之一，主要生理作用是促进垂体前叶合成和释放促甲状腺素，并能促进催乳素的分泌，它又是一种中枢神经谏U激剂，可以细8精神抑郁症。

In the present paper,the inheritance,morphological and anatomical char-acters,physiological and biochemical characteristics,the shoot and leaf growinghabit of the curly dwarf mutant "Zha′ai 76"from Malus baecata,and the re-productive charateristic of"Pingyi Tiancha"an apomictic type of Malus hupe-hensis,are systematically studied.

本文对山定子皱叶矮生型突变系&扎矮76&的遗传、形态、解剖、生理生化、枝叶生长等特性和苹果属无融合生殖类型平邑甜茶的生殖特性进行了系统研究，并探索了通过两种资源的杂交选育种子繁殖的苹果矮化砧品种的可能性，获得以下结果

That insight arose when Dr Ross DNA-fingerprinted 12 types of tissuefrom 39 dead marmosets, in order to work out how frequently cells containing atwin's genome occurred in different parts of the body.

上述见解源于罗斯博士的一系列实验–为了研究出含有一个双胞胎基因组的细胞出现于身体其他部位的频率，她从39只死去的狨猴身上取了12种生理组织的 DNA 指纹样品。

The 19 strains of bacilliform bacteria were identified by biochemical tests, part of their 16S ribosomal DNA were amplified, sequenced, and phylogenetically placed.

分离得到得19 株乳杆菌通过菌落、菌株形态观察以及多项生理生化等常规鉴定，并且通过16S rRNA 基因序列测序鉴定，确定这19 株乳杆菌分属于乳杆菌属内专性同型发酵类型中三个不同的种。

At a glance of the molecular mechanism, one gene encoding 218 amino acids was identified from cDNA-AFLP differential study and then named as Ipomoea batatas MADS-box 1 gene (IbMADS1) based on earlier studies. From sequence alignment and phylogenic analysis, IbMADS1 exhibited a typical type II-MIKC structure, including two conserve domains, MADS-box and K-box.

本论文针对从甘薯块根筛选出的MADS-box基因，IbMADS1（Ipomoea batatas MADS-box gene 1）进行分析，分别探讨该基因在甘薯各部位的表现方式、受植物荷尔蒙调节的影响，以及甘薯属中野生亲缘种间的基因表现歧异性，再进一步从转殖植物的外表形态了解此基因可能的生理功能。

The asymmetric hydrogenation of prochiral ketones is one of the most efficient methods of producing enantiomerically enriched secondary alcohols. The ruthenium complex RuCl_2[P(C_6H_5)_3]_2--DPEN(DPEN=1, 2-diphenylethylene-diamine) was applied to the asymmetric hydrogenation of benzalacetone.
