本研究以水中叶绿素a浓度为基础，鱼类食性为辅，发现使用本土种且具有经济价值之淡水圆蚌，来作为滤除水中藻类的生态方法颇具可行性，利用藻类吸收营养盐、圆蚌食用藻类、再将圆蚌移除之方式而达到降低水库营养盐能量的目的。

Armoracia rusticana leaves treated with lanthanum were determined in net photosynthetic rate and chlorophyll content. Changes in chloroplast ultrastructure were observed under transmission electronic microscopy.

测定了用稀土镧处理过的辣根叶片净光合速率和叶绿素含量，并用透射电镜观察了经La处理后辣根叶绿体超微结构的变化。

In vivo chlorophyll fluorescence excitation spectra at 675 nm emission wavelength of six phytoplankton species belonging to dinophyta and bacillariophyta were studied.

研究了甲藻和硅藻两个门类的六种浮游植物在发射波长为675 nm处的活体叶绿素荧光激发光谱。

This experiment researched the storage physiology of post-harvest and the effect of Calophyllum inophyllum L .

5%、2%对海红果贮藏生理及效果的影响，结果表明：涂膜处理可以明显抑制果实的叶绿素分解、硬度下降、可溶性固形物含量下降、Vc含量下降和酸含量下降。

The chlorophyll contents and photosynthesis decreased gradually with the increasing of Cu2+ concentration. The respiration rose gradually in the range of 0.01～10 mg/L Cu2+ and fell gently over 10 mg/L. These results indicated that Chlorococcum sp.

在1 mg/L Cu2+浓度下，绿球藻对Cu2+的去除率最高为90.5%；叶绿素含量及光合作用强度随Cu2+浓度的升高逐渐降低；呼吸强度在0.01～10 mg/L Cu2+浓度范围内逐渐升高，大于10 mg/L Cu2+则逐渐降低。

Large division of chiefly freshwater eukaryotic algae that possess chlorophyll a and b, store food as starch, and cellulose cell walls; classes Chlorophyceae, Ulvophyceae, and Charophyceae; obviously ancestral to land plants.

主要是淡水真核状态的藻类的一个大门，具叶绿素a和b，储备食物作淀粉、纤维素细胞壁；绿藻纲和轮藻纲；明显地祖先陆地植物。

Results showed that the peanut seeds soaked with the suitable rare earth concentration, not only increased chlorophyll content and photosynthetic intensity, but also chlorophyll in leaf cell enhanced. The chloroplastid texture intact, and the amounts of basal granule lamella increased with tight arrangement, and improved the absorption and transformation of light and energy.

结果表明，适宜浓度稀土浸种花生不仅提高了叶绿素含量和光合强度，而且还促进了叶细胞叶绿体的生长发育，使叶绿体结构完整、排列整齐，基粒片层数增多，紧密度高，从而有利于光能的吸收和转化，提高荚果产量。

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。
