The results showed that coverage, tiller density, turf quality, leaf chlorophyll and water content declined markedly along with turgidity under the persisting stress of heat and drought. Compared with mid-June, turf quality and leaf water content in mid-August had declined about 12.1%-49.8% and 14.2%-27.6%, respectively. Similarly, the activities of SOD and POD in leaves declined 36.5%-55.0% and 46.9%-65.7%, respectively, while the MDA content increased from 19.8% to 88.7%.

结果表明，随着夏季高温伏旱强度的增加和持续时间的延长，各品种的草坪盖度、密度、综合质量、叶片叶绿素含量和组织含水量均持续显著下降，8月中旬的草坪综合质量和叶片组织含水量分别比6月中旬降低了12.1%~27.6%和14.2%~27.6%；8月中旬叶片组织的SOD和POD活性分别比6月中旬下降了36.5%~55.0%和46.9%~65.7%，而MDA含量则增加了

There is a significantly different of seedling color betweent unpigmented and pigmented onion seedling by naked eye under black germination condition, the seedling color of red and yellow onion almost looks same, there are no significantly different of Chlorophyll contains.

The young grape plants grown under low light environment was more sensitive to methylviologen as compared to unshaded control. After MV treatment, the PS Ⅱ photochemical efficiency of young grape plants shaded decreased more than that of control, its chlorophyll and carotenoids were bleached by strong light more seriously.

将其移到自然强光下后，PSⅡ光化学效率下降，受到明显的光抑制；对光氧化的敏感性提高，强光和光氧化剂处理后，其光合机构PSⅡ的光化学效率降低幅度大于对照，而且叶绿素和类胡萝卜素受光漂白严重。

In order to manufacture Dye-sensitized Solar Cells of considerable efficiency under the current experimental conditions, we have adopted the process of even adhesion and spray painting to produce the nano-sized TiO2 porous films, and applied natural chlorophyll with N719 as the Dye Sensitizer; as for Electrolytes, we have selected a low volatile salt which has 1-/13 redox couple, and ITO conductive glass is used to be the conducting substrate.

本实验采用均胶和喷涂工艺制备得到TiO2纳米多孔薄膜，用天然叶绿素以及N719作为染料敏化剂，并选用含I-/I3-氧化还原电对的低挥发性盐作为电解质，以ITO导电玻璃作为导电基底，在现有的实验条件下，制备具有一定效率的染料敏化太阳电池***请不要用google等翻译工具，不然偶也不用提问了*********谢拉是太阳能电池方面的，以下是摘要中的一些专业词汇 TiO2纳米多孔薄膜 nano-sized TiO2 porous films 染料敏化太阳电池 Dye-sensitized Solar Cells 染料敏化剂 dye

ABSTRACT Fruit ripening is associated with a number of physiological and biochemical changes including degradation of chlorophyll, carotenoid biosynthesis, synthesis of flavor compounds, conversion of starch to sugars, cell wall solublisation and fruit softening.

果实的发育成熟涉及一系列复杂的生理生化变化，包括叶绿素的降解、类胡萝卜素的合成、淀粉向糖的转化、芳香性化合物的合成、细胞壁溶解和果实软化等。

The result indicated that the phenolic acid and its mixture could defer the remarkable time of wild oat seed germination, reduce seed germination rate, inhibit the physiological parameter and accumulated amount of dry matter to a certain extent, decrease the Root activity and chlorophyll content inordinately, and increase malondialdehyde level in seedling.

结果表明：酚酸类物质及其混合物可以显著延缓野燕麦种子发芽所需要的时间，降低最终的萌发率，对野燕麦幼苗的生理指标及干物质积累有一定的抑制作用，根系活力与叶绿素含量也有不同程度的下降，同时使幼苗体内丙二醛的含量显著增加。

Na2FlBr4Cl4 shows the maximum algaecidal activity, and the MLC value is 40μM with illumination and 90μM without illumination. From the research on the Na2FlBr4Cl4 against the growth of algae and the content of chlorophyll a, we obtains that xanthene derivatives have little effect on the growth of algae at low concentration and can restrain the growth of algae at middle and high concentration.

呫吨类化合物对铜绿微囊藻的测试结果显示：供试样品中对供试藻种活性最强的是Na2FlBr4Cl4，其MLC值为在光照条件下为40μM，在无光条件下为90μM；通过Na2FlBr4Cl4对铜绿微囊藻的生长量以及叶绿素a含量的影响的研究发现，在较低的浓度范围内，呫吨类化合物对铜绿微囊藻的生长没有太大影响，而在中高的浓度范围内，则能产生显著的抑制效应。

Effects of exogenous oxalate on photosynthesis, chlorophyll fluorescence and xanthophyll cycle in cucumber leaves under high temperature stress at 40℃ were studied.

在40℃高温胁迫条件下，研究了外源草酸对黄瓜叶片光合作用、叶绿素荧光参数和叶黄素循环的影响。

In June, grown in blue sheet had a lower Xanthophyll 444.5、467and 470 nm than other colorful sheets.

叶绿素b 653 nm在6月栽培时期，蓝色不织布比其他四种颜色不织布高，其他颜色不织布均较低。

A primary investigation into the separation of carotene, xanthophyll s and chlorophylls on reversed-phase C18 supercritical carbon dioxide chromatography was made in this study.

在本项研究中，应用反相C18固定相超临界CO2色谱对胡萝卜素、叶黄素和叶绿素的分离进行了初步的探索。

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.
