叶绿素

Its main features are: algae body as a single cell or even into a variety of groups; cell walls composed of silica and pectin, but also by the structure of the shell and the shell under the combined set of the Cheng, vertical section view was "soap-box"-shaped; in the upper and lower shell surface of the shell are patterns arranged in patterns on both sides of the main mode of symmetry and radial symmetry is divided into two categories, for the classification of the most important basis; be able to campaign Type in the shell has a shell side seam, can not be changed no shell seam types; pigment body sheet or ribbon, 1 or 2, or for multiple small discoid, yellow green or brown, containing chlorophyll a, c, also contains fucoxanthin and silicon A flavin and other photosynthetic pigments; storage material mainly for oil droplets; reproduction mainly for cell division and cell division in diatoms obvious features are: each cell division, resulting from two sub-cells,, only one and the mother cell and so big, the other one is smaller.

其主要特征是：藻体为单细胞或连成各式群体；细胞壁由硅质和果胶质组成，而且在结构上都是由上壳和下壳套合而成，纵断面观呈&肥皂盒&形；在上下壳的壳面上有花纹，花纹排列的方式主要分为两侧对称和辐射对称两大类，为分类上的最重要依据；能运动的种类在壳面都有壳缝，不能动的种类均无壳缝；色素体片状或带状，1个或2个，或为多个小盘状，黄绿色或黄褐色，含叶绿素a、c，还含有墨角藻黄素和硅甲黄素等光合色素；贮藏物质主要为油滴；繁殖方式主要为细胞分裂，硅藻的细胞分裂的明显特点是：每次细胞分裂所产生的2个子细胞中，仅有1个和母细胞等大，另1个则稍小。

Or 3cm brown layers occurred in the bottom ice in later April and November,with highest chlorophyll a values of 88.3 and 2810mg/m 3 respectively,and the comparing cell numbers were 3.5×10 6 and 1.21×10 8cells/l.

冰底有色层出现在4月下旬和11月下旬，集中于冰底2～3cm，叶绿素a最高含量分别为88.3mg／m3和2810mg／m3，相应的冰藻数量分别为3.5×106和1.21×108个／升。

When oxygen is present in cells, polyphenol oxidase enzymes in the chloroplasts rapidly oxidize phenolic compounds naturally present in the apple tissues to o-quinones, colorless precursors to brown-colored secondary products.

当氧存在于苹果组织的细胞中时，叶绿体（含有叶绿素和进行光合作用的地方）中的多酚氧化酶，会迅速地将天然存在于苹果组织中的酚类化合物氧化为邻醌。

It contains a lot of chlorophyll on the human body and a variety of useful ingredients such as amino acids, can extract the natural flavors and fragrances and food additives, aromatic smell, smells have a sense of return to nature.

它含有大量对人体有益的叶绿素和多种氨基酸等成份，可提取天然香精香料和食品添加剂，气味芳香，闻上去有回归大自然的感觉。

Huang bean sprouts in the decomposition of chlorophyll inside the human body can nitrite amines, which played rectal cancer prevention, such as the role of a variety of gastrointestinal cancer.

黄豆芽中的叶绿素能分解人体内的亚硝酸胺，进而起到预防直肠癌等多种消化道恶性肿瘤的作用。

We research the effect of different fertilizer combination and leaf minerals content on the photosynthesis of rubber tree mainly from photosynthetic rate,stomatal conductance,chlorophyll content...etc.,and filter the best fertilizer combination which promoting rubber tree photosynthesis efficiently proceeding, the aim is to provide basal theories for the cultivation of rubber tree.

研究了不同施肥对光合速率、气孔导度、叶绿素含量等方面橡胶苗木叶片光合特性的影响，并从中筛选出促进橡胶树光合作用高效进行的最佳肥料组合，旨在为橡胶树的生产栽培提供理论依据。

Adopting international advanced nanometer ultra micro powder technology and biological enzymolysis technology, it can perfectly cover face defect and line crack, adjust uneven skin tone, smoothen skin, build up skin transparency, in the meantime, it can resist pollution, improve skin tone, make your skin like crystal and lotus flower.

好处：精选天然珍珠精华、叶绿素逆时无痕修复因子、100%纯芦荟油等多种活性美肤成份，采用国际先进的的纳米超微细粉末技术和生物酶解技术，完美遮盖面部瑕疵及细纹，调整不均匀肤色，平滑肌肤，缔造肌肤透明感的同时，抵抗污染，提亮肤色，令肌肤晶莹剔透宛如出水芙蓉。

Some similar responses were observed in the both species.(1) After saturating illumination for 3 h, the original fluorescence Fo increased while the PSⅡ photochemical efficiency Fv/Fm declined significantly, but these parameters could largely recover to the levels of dark-adapted leaves after 3 h of subsequent dark recovery.(2) No net loss of the D1 proteins occurred after the saturating illumination.

一方面，大豆和南瓜叶片在饱和光下产生一些相同的变化：（1）经过3小时饱和光处理，它们的初始叶绿素荧光参数Fo都明显升高，而PSⅡ光化学效率Fv／Fm都明显降低，但经过随后的3小时暗恢复后，Fo和Fv／Fm都可以恢复到初始暗对照的水平；（2）在饱和光处理和随后的暗恢复过程中都没有发生D1蛋白的净损失。

The results showed that plant height, stem diameter, height of ear position, leaf area index, chlorophyll content in leaves, biomass of shoots, characteristics of ear, grain yield and harvesting index were significantly influenced by planting density and mode.

结果表明：密度和种植方式对两个品种的株高、茎粗、穗位、叶面积指数、叶绿素含量、干物质积累量、穗部性状、籽粒产量和经济系数的影响达到极显著水平。

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。
