叶绿素

Hemiparasite A parasitic plant that has chlorophyll and can photosynthesize, but depends on another plant for its water and mineral salts, e.g. mistletoe.

半寄生植物：是一类含有叶绿素并能进行光合作用的寄生植物，但是它们依赖其它植物提供水份和矿物盐类，例如檞寄生。

In iron-deficient cells, photosynthetic pigments content decreased, efficiency of photosynthesis was low, With the increase of the concentration of the iron-chelator 2, 2'-Dipyridyl in media, Fv/Fm decreased, indicating photoinhibition increased, the results were consistent with previous research; Heterocyst induction had one delayed time dependent on the status of iron-deficiency, More severe of the iron-deficiency condition, more late of the heterocyst induction, It is possible that certain iron-related genes may directly regulate heterocyst development; under different iron limitation conditions, Protein pattern were different, more serious of the iron-deficiency conditions, less bands of the protein pattern, We could not find the iron-deficiency induced protein; In general the toxic effects of ROS were potentiated by excess iron, But our results revealed that even under iron-deficiency conditions, Oxidative damage existed.

铁限制的细胞光合色素含量下降，光合作用能力下降，随着铁螯合剂2，2'-dipyridyl浓度的增加，叶绿素荧光F〓／F〓逐渐降低，显示光抑制变强。与前人的研究结果相似；依赖铁缺失状态，异形胞诱导有一段推迟的时间，铁缺失越严重，诱导越迟，推断某些铁相关的基因会直接调节异形胞发育；在不同铁营养条件下，蛋白质图谱的变化趋势很明显，缺铁越严重，则蛋白质谱带数愈少，但本文未能找到特异诱导蛋白；一般认为铁过量情况下ROS产生加强，本文结果显示即便在铁缺失条件下，也有氧化胁迫伤害，而且缺铁越严重，活性氧伤害越大。

C〓 thiophene didn't exist in aromatic fraction at 200℃, but very abundant at 300℃, indicating that heterotrophy resulted in the disappearance of chlorophyll which had transformed into more stable compounds with phytane side chain.

在200℃热模拟产物芳烃组份中不存在C〓噻吩，而300℃热解产物中该化合物含量较高，这可能暗示着异养黄化作用导致了叶绿素消失，并转化为更加稳定的具植烷侧链化合物。

This study clearly showed that mosaic variation was caused by chlorophyll deficiency mutation of shoot tip histogen layer-Ⅱ;tissue and organs originated from the layer-Ⅱ couldn't synthetize chlorophyll,thus induced albino; the albino variation appeared yellow green mosaic because layer-Ⅱ was displaced by layer-Ⅲ partly.

研究表明，其变异原因是由于茎尖分生组织的L -Ⅱ组织原层发生失绿突变，致使其衍生的组织和器官不能合成叶绿素，从而形成白化现象；又由于L -Ⅱ与L -Ⅲ组织原层层间发生部分代换，致使白化突变呈黄绿镶嵌的花斑。

Eichhornia crassipes and Hosta ventricosa is used as experimental material to study Cd stress on the two plants growth, chlorophyll content, MDA and root peroxidase activity and other physiological indicators to investigate the effect of Cd on the toxic effect of higher plants,with a view to Cd pollution Phytoremediation providing a theoretical basis.

以凤眼莲和紫萼玉簪为实验材料，研究镉胁迫对凤眼莲和紫萼玉簪的生长、叶绿素含量、丙二醛含量及根系过氧化物酶活性等生理指标的影响，探讨镉对高等植物的毒害效应，以期为重金属镉污染的植物修复技术提供理论依据。

Both of Eichharnia crassipes and Hosta ventricosa can grow normally in a single nitrogenand phosphorus stress condition, The higher the concentration of nitrogen and phosphorus in waterthe higher the chlorophyll content and dry matter content in plants, it means the growth of plants isgood, This proves that Eichhamia crassipes and Hosta ventricosa has a very strong ability to adaptin a single nitrogen and phosphorus pollution water, they can be used for repairing a singlenitrogen and phosphorus pollution water.

在单氮和单磷胁迫条件下植物都能够正常生长，并且水体中氮、磷浓度越高凤眼莲和紫萼玉簪体内的叶绿素含量及干物质含量就越高，说明两种植物的生长状况就越好，这一点证明两种植物对氮、磷污染的适应能力都很强，可以用于修复单氮和单磷污染水体。

Some morphological and physiological parameters of Li-1 and TM-1 weremeasured in this experiment. It showed that the contents of chlorophyll in Li-1 washigher than that in TM-1, but leaves areas and photosynthetic rate of Li-1 were lowerthan that of TM-1. The results indicated that lower photosynthetic efficiency and lackof assimilates would decrease the biomass of Li-1, and exhibited other abnormalphenotype such as curled leaves and fiber hypogenesis.

通过对突变体与标准系形态指标和生理指标的测定比较发现，虽然突变体的叶绿素含量高于标准系，但叶面积和光合速率低于标准系，说明生成同化产物的效率较低，这是造成突变体植株生物量较小的直接原因。

The results show that the content of nutrient in ice layer was about one-third that of it in water and the content of chlorophyll a in ice layer was about one-fifth that of it in water during icebound season.

结果表明，冰封条件下，冰层中营养盐的含量约为水体中的1/3，叶绿素a约为水体中的1/5。

For additional odor control, 1-2 capsules may be added directly to an empty colostomy or ileostomy bag as needed.

特别建议：如欲加强口气控制，可根据需要将1-2粒叶绿素 Chlorofresh 直接添加至结肠造口或回肠造口袋。

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。
