The comparative study on vegetation background survey of the stationsand the comparison on level of phytocoenology on zonal habitats indicates thatthe diminishment of the numbers of families,genus and species,compositionof life types,diversity of communities and habitats,;and the increscence in theproportion of photosynthesis functional groups of C3/C4 plant,richness ofspecies,density of tussock and tiller,diversity of species,evenness,leaf areaindex,leaf area duration,dry matter production of communities alongside thelatitude increasing and the temperature decreasing;and the dynamic curve ofthe community productivity also tend to steadily increase along with thetemperature going up and the heat accumulation gradually in moderate-temperate steppe station from violent fluctuation along with seasonal badly-distribution of precipitation in warm-temperature steppe station;manifestingthat transformable tendency of productivity pattern of the community from morevigorous net assimilation,sparser and higher crops stricture of tussock and tiller,and possession on more resources by less species inclined to thicker in densityof crops,superior effectiveness of multi-leaves and pattern of multi-speciesresource sharing,reflecting that bigger disparity of the vegetationcharacteristics and the style of the community growth in the two differentthermal-type steppe stations owing to background of natural-historicenvironment and combination of water and heat.

内蒙古草原区两个不同热量型研究站点植被本底调查和显域地境群落学水平的比较研究表明：随纬度增加和气温降低，植物科、属、种的数目，生活型组成，群落类型和生境类型的多样性均趋于减少，而C3/C4光合功能群比值和群落的物种丰富度，株丛密度，物种多样性，群落均匀度，叶面积指数，叶面积持续时间和群落干物质生产能力均趋于增加，群落生产力动态曲线从随天然降水的季节分布不均而剧烈波动趋向于随气温逐渐升高和热量逐步积累而稳定增长，显示出两站点植物群落从较为旺盛的群体净同化作用、较为稀疏高大的群体结构和少数物种占有较多群落资源的生产力格局向较高的群体密度、优良的多叶性能和多物种资源共享的群落生产力格局转变，反映出在内蒙古草原区不同的自然历史环境背景和不同的温度条件及其水热组合状况影响下，两个不同热量型草原站点植被性质的分异特征和显域地境群落生长模式的较大差别。

Path analysis showed internodal distance,first lateral branch number and whole-plant leaf weight with a significant positive effect on vindoline content (P.05), with path coefficients of 0.959, 0.716 and 0.431 respectively, which suggests that internodal distance, first lateral branch number and whole-plant leaf weight are the important factors in breeding C.

通径分析结果表明，长春花的主要农艺性状中，节间距、一级侧枝数和全株叶片重对文多灵含量的正影响达到了显著水平(P.05)，通径系数分别为0.959、0.716和。431，说明节间距、一级侧枝数和全株叶片重可以作为高含量文多灵长春花品种选育的重要参考指标。

Our previously study has been showed that transgenic N.benthamiana and N.tabacum plants expressing TYLCCNV DNAβC1 developed pleiotropic morphologic abnormalities such as leaf curling,distortion and interveinal protuberances on the abaxial surface. To determine whether theβC1 protein of TbCSY is also responsible for symptom induction,we prepared transgenic N.benthamiana and tomato plants expressing the TbCSV DNAββC1.Of the rooted plantlets,only 10%of transgenic N.benthamiana plants were moderately abnormal,including upward leaf curling.

DNAβ互补链上编码一个保守的ORF，即βC1，对TYLCCNV DNAβ的βC1的突变发现它编码一个症状决定因子，表达TYLCCNV DNAβ的βC1的转基因烟草产生曲叶、畸形和叶背面组织增生等发育异常的表型，而大部分转化TbCSV DNAβ的βC1基因的烟草和番茄植株均与正常植株类似，只有少数烟草表现出轻微叶上卷表型。

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.
