Tree shrew, which was the representative tropic and sub-tropic small mammal distributed in the south of china, was studied on cold adaptative characters of individual and molecule levels during the press of low temperature as the experimental animal in our research.

本论文以分布于我国南方的典型热带、亚热带小型哺乳动物，中缅树鼩，为研究对象，从个体水平及分子水平对低温胁迫下的冷适应特征进行了研究。

SOD activity of Agrostis stolonifer was improved under a certain Cu and Pb concentration.

在一定浓度的Cu、Pb胁迫下，翦股颖中的SOD活性升高，但浓度过大时，SOD活性则下降。

By using fluorescence spectrophotometry method,a systematic study was conducted to determine the effect of cadmium and lead ion stress on reactive oxygen species in creeping bent Agrotis stolonifera leaf tissue.

通过2种重金属离子和抗霉素A处理匍匐翦股颖Agrotis stolonifera幼苗叶片，利用2，'7'-二氯荧光黄双乙酸酯溶液对重金属胁迫和抗霉素A处理后叶片中产生的过氧化氢(H2O2)反应形成具荧光物质DCF的特性，用荧光光度分析法分析了叶片中H2O2产生与积累规律。

Eight Alnus cremastogyne clones, which simulated with different concentration of sodium chloride, were measured with four physiological indexes, including SOD activity, MDA content, chlorophyll content and soluble proteins content.

以不同质量分数的盐胁迫对桤木Alnus cremastogyne 8个无性系，在盆栽条件下测定叶片中丙二醛质量摩尔浓度、超氧化物歧化酶活性、可溶性蛋白质量分数和叶绿素质量分数的变化。

Pot experiments were carried out to study the effect of petroleum hydrocarbon pollutants in soil on physiological and chlorophyll fluorescence response of Forsythia suspense, Hydrangea paniculata and Amorpha fruticosa.

通过盆栽试验，研究了不同浓度的石油烃胁迫对连翘、大花水桠木、紫穗槐生理及叶绿素荧光特性的影响。

The results showed: 1 With longer water stress, the growth and accumulation of dry matter of A.persica and Amygdalus communis L. was the fastest when the soil relative water content is 80%.The growth and accumulation of dry matter of A.persica and Amygdalus communis L. was restrained when the soil relative water content is 40% and 20%.But both of them still kept on growing the biomass weight.

主要结论如下： 1随着胁迫时间的延长，毛桃和石头扁桃在土壤相对含水量为80%时生长最快和干物质积累量最大，土壤相对含水量为40%和20%时生长明显受到抑制，干物质积累量降低，但仍保持一定的生长。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
