The study aimed to explore the effect of water on chlorophyll,POD activity,membrane-lipid peroxidation,etc of different Coix lacryma-jobi L.cultivars in tillering stage.

It is shown from the assessment results that (1) both the TN and TP fluxes discharged from the Changjiang River to the Changjiang River estuary sea area increased continuedly, the DIN concentration in the sea areas increased continuedly, and the Si concentration decreased continuedly, which resulted in the significant changes in N/P/Si ratios;(2) the chlorophyll a concentration in the sea areas increased continuedly, and the significant changes in community structure of phytoplankton occurred;(3) the species and biomass of benthos declined greatly, and the bottom oxygen-poor water area increased significantly;(4) the range and occurrence frequency of red tide events in the sea areas increased greatly, and the algal toxic infection events of mussel were frequently found in the sea areas.

结果表明，长江向长江口海域输送总氮和总磷通量持续增大，长江口及其邻近海域无机氮浓度持续增高而硅浓度持续下降，并由此导致N/P/Si与比值的显著变化；该海域叶绿素a浓度持续增大，浮游植物群落结构也发生了显著变化；该海域底栖生物种类和生物量都大大减少，底层水低氧区面积也显著扩大；该海域赤潮事件无论是规模还是频率都大大增加，藻类毒素DSP/PSP贻贝传染事件也时有发生。

Our research indicated that from flowering to harvest stage of wheat,the photosynthetic rate,chlorophyll contents,soluble protein contents and conversive efficiency of light energy in L14 wheat leaves apparently declined more quickly than that in wheat variety 935031,but the beginning time when respectively relevant parameter declined was different.

结果表明：自开花至成熟期，鲁麦L14小麦叶片光合速率、叶绿素含量、可溶性蛋白含量及光能转化效率的下降速度均明显快于小麦品种935031，但是各相关参数降低的起始时间不同，自开花后30 d鲁麦L14的叶片已经开始干枯，而935031小麦品种到成熟时大部分叶片还保持绿色，说明小麦叶片早衰与光合能力的下降有密切关系。

Crispate were studied. when Cr(superscript 6+) was more than 5 mg/L, the plant height, leaf area, yield and the ratio of chlorophyll a/b obviously were decreased with the increase of Cr(superscript 6+) concn.

结果］当Cr(上标 6+)浓度＞5mg/L时，皱叶留兰香株高、叶面积、产量及叶绿素a/b比值随着Cr(上标 6+)浓度的升高而明显下降。

Seeds usually 3-angled; testa thin, crustaceous, smooth to reticulate or verruculose, sometimes adaxially invaginated at hilum; endosperm copious; embryo straight to distinctly curved, lacking chlorophyll; cotyledons broader and much longer than radical.

种子通常3倾斜；种皮薄，壳质，平滑到网状或者小瘤状，有时正面在种脐凹入；胚乳丰富；胚直或明显弯曲，缺乏叶绿素；子叶较宽，远长于胚根。

UV-B absorbing capacities of methanol and cell-bound alkali extractable phenolics were measured in leaves of potted one-year-old seedlings of Pinus massoniana, Schima superba, Cryptocarya concinna, Castanopsis fissa and Castanopsis chinensis to investigate the UV-B protecting strategy in plants exposed to full sunlight.

通过测定马尾松和荷木，及黄果厚壳桂、藜蒴和锥树叶片中甲醇提取物和细胞壁碱性酚类提取物中UV-B吸收物质的含量，以及叶片叶绿素含量和比叶面积，研究全日光强下植物对UV-B的防护策略。

There were less Na+ in root, stem and leaf, more free proline and soluble sugar in leaves, and higher shoot relative water content in Cucurbita ficifolia.

结果表明，在对照和盐处理条件下，两种黄瓜嫁接苗叶面积、干物重、相对含水量、根系活力、叶片中叶绿素含量、可溶性糖含量、K~+和Ca~(2+)含量均大于自根苗。

"Dodder:any of various leafless, annual parasitic herb s of the genus Cuscuta that lack chlorophyll and have slender, twining, yellow or reddish stems and small whitish flowers."

菟丝子：菟丝子属植物一年生无叶寄生草本植物菟丝子属，缺少叶绿素，有细长蜷曲黄色或浅红色茎，开白色小花。

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。
