地法系统是一种新型的技术，基因转化的水生植物浮萍，使生物候选产品的生产。

The concentrations of TN in all the treatments decreased to lower levels at the middle and latter periods of the experiment, and those of TP also decreased at larger extents. Compared with the control, DDT at 200μg·L-1 inhibited growth and reproduction of the dominant macrophyte Lemna minor, but the reverse was found for DDT at other concentrations.

和对照组相比，200.0μg·L-1的DDT对大型水生植物优势种类浮萍的生长繁殖具有抑制作用，而其它浓度的DDT具有促进作用；DDT对菹草的生长影响不明显。

As for the monitor of water pollution, Lemna minor, Spirodela polyrrhiza shleid and Azalla imbricate Nakai could be used as the monitors for the naphthalene pollution in water body because of their sensitivity to it.

在净化过程中，萘对5种水生植物产生生理毒害作用，且随萘浓度的增加显示出明显的毒害效应，表现为呼吸强度受到抑制，叶绿素含量降低；对POD而言，凤眼莲、喜旱莲子草随萘浓度增加逐渐升高，而浮萍、紫萍则表现出先升高然后降低，满江红一直降低。

By imitating different concentration of Cd2+ Cu2+ Cr3+ Cr6+and Zn2+polluted water environment,we mainly studied their toxic effects on aquatic piants by means of measurement of physiologicai indexes and electron microscopy observation as well as the relieving to Cu2+ injury of antioxidase enzyme system in Lemna minor L. and Vallisneria asiatica Miki in this paper by throwing Ce.the experimental results showed that Cd2+ Cu2+ Cr3+ Cr6+ and Zn2+ might injure photosynthetic systems, protective enzyme system, substance metabolism systems and cell ultrastructure of the plant.

本文通过模拟不同浓度梯度的重金属Cd~(2+)、Cu~(2+)、Cr~(3+)、Cr~(6+)和Zn~(2+)污染环境，利用生理生化测定、扫描电镜、透射电镜、气相色谱及激光共聚焦等实验手段，研究了四种金属离子对不同生态型的水生植物的毒害影响，初步探索了Ce对浮萍Cu害的缓解效应和La、Zn及其交互作用对浮萍活性氧清除系统影响。

Finally, I apply the concepts of dragonfly's biotopes to Kanding ecological park. Various types of lentic and lotic freshwaters surrounded by abundant hydrophytes and multi layers trees are planned. Besides, ecological landscape design with construction proceeds in terms of the following aspects: site gradation and sewage system, circulations and land use, plantation types and materials, and ecological construction methods with waterfront design details.

最后应用蜻蜓生物托邦之概念於崁顶生态公园，其生态地景设计在规划层次上考虑不同型态之流水与止水域空间的配置以及复层密林植被与丰富之水生植物的应用；并且从整地与排水、土地使用区分与动线系统、植被类型与植材选定、生态工法与亲水细部构想进行设计与营造。

There were many aquatic plants have the potential utilization in water garden, such as Lythrum salicaria, Scirpus validus cv.

除了目前常用的种类外，千屈菜、花叶水葱、泽泻、鱼腥草、苦草等水生植物均具有较大的应用前景。

Crassipes and other aquatic plants pulssingall combination in series showed efficiant removing ability for nitrogen and phosphorus,and the inlay combination of E. crassipes, Trapa manshurica and Nymphaea tetragonashowed better removal efficiency for redox organic pollutants than the inlay combinationadding other combination in series.

人工复合生态系统试验表明，凤眼莲与水生植物的镶嵌组合加各级串联组合能有效去除氮磷，而对于还原性有机污染物，凤菱睡镶嵌组合的去除效果相对要好于镶嵌组合加各级串联组合。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
