叶绿素的

The results showed that there was a significant linear correlation between SPAD value and chlorophyll content; SPAD value varied significantly between two varieties.

结果表明；苹果叶片的叶绿素含量与SPAD值呈线性相关；品种间的SPAD值和光谱反射率都存在差异。

Relationship about the SPAD value and chlorophyll content for 9 varieties of mulberry leaves was established, while the regression models were given.

建立了9个品种桑叶的叶绿素含量与SPAD值之间的关系，并列出了方程。

The resuits showed that there was significant difference of SPAD among different leaves under same nitrogen level.

结果表明，在同一施氮水平下，小麦植株不同叶片SPAD值及光舍速率均为：旗叶〉倒二叶〉倒三叶〉倒四叶，说明小麦叶片叶绿素含量及光舍速率在植株上的分布特征相对固定，受施氮水平的影响较小。

The field acid rain spray system was adopted to study the effects of simulant acid rain on leaf injury and chlorophyll content, photosynthesis, permeability of cell membrane, stomatic impedance, and transpiration intensity of 11 crops.

采用田间酸雨喷淋系统在南京中山植物园研究了模拟酸雨对11种农作物的叶片可见伤害和叶绿素含量、光合作用、细胞膜透性、气孔阻抗、蒸腾强度的影响。

And DO level only at 2.9 mg/L in walking catfish's grow-up ponds. The chlorophyll a in sweetfish pond and walking catfish pond were 3.43 and 170.43 mg/ m3, respectively.

香鱼养殖池的溶氧都在5 mg/L以上，胡鲇养殖池溶氧平均值为2.9 mg/L，两个养殖池的叶绿素a平均值分别为3.43和170.23 mg/ m3。

This happens in a so called reaction center inPhotosystemⅡ, where a tetrameric chlorophylls (P680) absorb the solar light andinitiate photoinduced electron transfer reaction to the acceptors, quinone A and B. Thephoto-oxidized P680 retrieves the electron from a Mn4Ca cluster via a tyrosine, thelatter components are also called oxygen evolving center. After 4 photo-processes, twomolecular water are oxidized to a molecular oxygen.

在光系统二的活性中心，叶绿素P_(680吸收太阳光，将电子传递给电子受体、醌A和醌B，同时光氧化的P_(680)~+从释氧中心中得回电子(通过Tyr_z氧化Mn4Ca簇)，经过四次光诱导电子转移，两分子水最终被氧化生成一分子氧气。

The results have shown that there exist excitation energy transfers from the component at 232 nm in PS II proteins to the tyrosyl residues, and from these two amino acid residues to chlorophyll a.

在PSII蛋白质内部，存在着232 nm处的组分与酪氨酸之间以及这两种氨基酸列基与叶绿素a之间的能量传递。

A lot of study showed that: the main reason for this was that plantlets grew in the sealed vessel and depend on sugar in the medium, which resulted to poor development of leaf, unflexible open-close of stomata and low chlorophyll content. So, plantlets lose photosynthetic ability.

国内外许多研究报道认为，组培苗生长不够健壮主要原因是组培小植株长期在密闭环境中生长，靠培养基中的糖进行异养，而导致叶片表层结构发育差，气孔开闭功能差，叶片小，叶绿素含量低，最终使小植株丧失了光合作用的能力。

In order to discuss the effects of bio-organic manure on ginger（ Zingiber officinale Rosc.）yield, the leaf photosynthesis and chlorophyll fluorescence in different fertilizer treatments were studied in the experiment using the cultivar 'Laiwu da jian'.

为探讨生物有机肥对生姜的增产效果，以'莱芜大姜'为试材，研究了不同肥料配比对生姜生长及叶片光合作用和叶绿素荧光特性的影响。

Three types of Zizyphus jnjuba Mill were used as the research materials to study the diurnal changes of chlorophyll fluorescence parameters.

以沾化冬枣、龙枣、黄河枣王三种不同的枣树为材料，研究其叶绿素荧光参数的日变化。

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。
