叶绿素

4During chilling stress,Ca~(2+)treatment could delay the decrease of chlorophyll content and RuBPCase activity;And it could enhance Pn,Gs,Tr,the saturation point and dark respiratory speed of the heat-shock-induced cucmber seedings.So it reduced Ci.But the EGTA treatment had the opposite effect.

4钙处理能减缓热激黄瓜幼苗冷胁迫下叶绿素含量和RuBPCase活性下降，提高Pn、Gs、Tr、光补偿点和暗呼吸速率，降低Ci；而EGTA处理则相反。

A: The human eye is more sensitive to differences in some specific colors. For instance neutral grays, skin tones, chlorophyll greens and sky blues, so we choose these colors first. Then we choose saturated red, green, blue, cyan, magenta and yellow. After that we tried to fill the remaining big cavities in the color space.

答：人类眼睛对某些特殊颜色的差别较为敏感，例如中间灰色，皮肤调，叶绿素绿，天空蓝，我们预先选择了这些颜色然后饱和的红绿蓝洋红靛蓝和黄色，之后我们尝试填入色彩空间的剩余大凹处。

Using arid area (annual rainfall about 200mm) and dankness area (annual rainfall about 600mm) contrast test, determining the new potato variety's drought resistance, chlorophyll A, B content and CAT activity in the different growth period, study the relation between chlorophyll content, CAT activity and the drought resistance.

采用干旱地区（年降雨量200 mm左右）与阴湿地区（年降雨量600 mm左右）对比试验，测定马铃薯品种生育期的叶绿素a、b含量和CAT活性，研究其与抗旱性关系。

The internal conversion processes of chlorophyll a in solvents are studied based on the reduced density matrix theory.

采用约化密度矩阵理论研究了溶液中叶绿素a分子的内转换过程。

Strain 153 could improve the content of chlorophyll in leaves and enhance the deoxidize intensity of root so as to promoting growth.

放线菌153可通过定殖提高植株体内的叶绿素含量以及根系还原强度而促进番茄和茄子的生长。

The study aimed to investigate the effect of heavy metal cadmium stress on the seed germination, leaf chlorophyll and isozyme of Dianthus caryophyllus.

［目的］研究重金属镉胁迫对石竹种子萌发、叶绿素及同工酶的影响。

The spectral reflectance of dichondra turf was studies by measuring the leaf relative water content, chlorophyll content and soil water content under different drought levels.

通过在不同灌水处理下马蹄金草坪干旱胁迫试验，对草坪反射光谱的变化及所对应的叶片相对含水量、叶绿素含量以及草坪外观变化进行测定。

All showed strong chlorophyll a fluorescence signals originating from the dinoflagellate endosymbionts.

均具有很强的叶绿素a荧光信号，这些信号来源于体内共生的甲藻。

For the determination of the chlorophyll in seawater, pigments of marine algae are extracted with 90 % acetone by the following three methods: 1 grinding in a homogenizer, 2 extracting by placing the samples in darkness for a period of time,and 3 using a sonic disintegrator.

本文讨论了用90％丙酮从海藻中提取叶绿素进行测定的三种提取方法(研磨法、浸泡提取法、超声波粉碎法)的最佳条件。并对三种提取方法的提取效率进行了比较。

The effect of gamogenesis ,chlorophyll,superoxide dismutase and catalase of Egeria najas by different concentrations of suspended silt was studied.

研究了悬沙对细叶蜈蚣草营养生殖、叶绿素、抗氧化酶(超氧化物歧化酶和过氧化氢酶)等影响。

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。
