Chlorophyll fluorescence transient kinetics of Reboulia hemisphaerica under different simulated nitrogen deposition conditions was studied.

对石地钱Reboulia hemisphaerica在不同模拟氮沉降条件下的叶绿素荧光动力学特征进行了研究。

The annual dynamics of Brachionus populations in Lake Jinghu of Anhui Province, China was studied in the year 2003, and the relationships between their body volumes, egg volumes as well as relative egg volumes and the ecological factors including water temperature, Chl-a concentration were regressively analyzed.

对镜湖臂尾轮虫种群的周年动态进行了研究，测量和分析了它们的个体大小、卵大小和相对卵大小及其与水温和叶绿素a浓度等生态因子间的关系。

However,different periods were found in middle and bottom waters, due to the influences of tidal induced physical forcings such as resuspension and stratification.

表层叶绿素α浓度、微微型浮游生物和病毒丰度的周日波动呈现典型的半日周期(11-13小时)变化，而中层和底层由于沉积物再悬浮作用和水体层化现象的影响，波动周期与表层明显不同。

Relative to nitrogen topdressing in prophase, it mainly due to retroposition can provide nutrients for the wheat during flowering and grouting. Another way, it can help slow down the decline in leaf area and leaf chlorophyll content and photosynthetic rate during later stage, to meet the nutritional requirements during developmental stage of grains.

结合以往试验结论，本试验推断认为由于追氮时期后移既有利于开花和灌浆阶段养分的需要，同时有利于延缓小麦生长后期有效叶面积、叶绿素含量和光合速率的急剧下降，从一定程度上满足籽粒发育阶段的营养所需。

玉米；水分胁迫；复水；叶绿素；光合速率

The recovering ability of them were strong under light and moderate water stress, but weak under severe stress after rewater ing and chlorophyll content still declined during primary period of rewater ing.

水分胁迫下玉米叶片光合速率和叶绿素含量下降，复水试验表明，二者在轻度和中度胁迫下较易恢复，重度胁迫下恢复能力很弱。

The nitrate reductase activity,chlorophyll concentration and nitrogen content of tobacco leaf and total absorption area of tobacco rhizotaxy were significantly or extremely sign ificantly correlated with nitrogen concentration.

结果表明，不同基因型烟草对氮素营养的响应有明显差异，其硝酸盐还原酶活性、叶绿素含量、根系总吸收面积、氮含量均与氮浓度呈显著或极显著相关。

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。
