浮萍

Energy content in the Lemna diet was lower (250 kcal/lOO g) than that in the other two diets (300 kcal/ 100 g).

能源的浮萍饮食含量低于（250千卡/应用LOO g）在其他两个饮食（300千卡/ 100克）。

Highest values were recorded in fish fed Lemna.

最高值分别录得鱼喂浮萍。

The LEX System is a novel technology that genetically transforms the aquatic plant Lemna to enable the expression of biologic product candidates.

In this study, the productivity of Lemna perpusilla and Spirodela polyrrhiza, two of the most found duckweed species in Taiwan, was compared when cultured for 21 days in various environment: winter (15.9±2.3℃) or spring (23.1±1.2℃), without and with the presence of sediment, and without and with fertilization. It was found that L.

本研究比较台湾最常见的两种浮萍Lemna perpusilla及Spirodela polyrrhiza当培养在不同环境：冬天(15.9±2.3℃)或春天(23.1±1.2℃)，有或无底泥，以及有或无施肥21天后的生产力。

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。

In order to explore the feasibility of using native plant to evaluate and indicate water quality synthetically, we investigated the integrated evaluation and indication effect of Lemna paucicostata, an endemic species of Lemana in China to the water qualities of different sources（tap water, pond water pooled from rain rainwater uniquely, lake water received multiform sewage, and leachate）.

为探讨利用我国本土植物进行水质综合评价和指示的可行性，试验研究了我国特有的浮萍属植物——稀脉萍对不同来源水（自来水、雨水为唯一来源的池塘水、接纳多种排放废水的湖水及垃圾填埋场渗滤液）水质的综合评价和指示效果。

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。

The membrane leakage rate and chloroplast ultrastructure were investigated in the fronds of two duckweeds,Lemna minor L.and spirodela polyrrihizaSchleid,cultured in distilled water and in diferent pH values(5.5,4.5,3.5,2.5)of simulated acid rain for 48 h.

用蒸馏水和不同pH值(5.5，4.5，3.5和2.5)的模拟酸雨培养浮萍Lemna minor L。

Any small or minute aquatic plant of the family Lemnaceae that float on or near the surface of shallow ponds.

浮萍科的任何一种小的、水生的植物，经常漂浮在浅水塘的表面上。

The reasons of iron ions content overproof in grade Ⅱ desalting water system,such as variation water quality,contamination of regenerant , operation adjustment of pretreatment system and switching operation of bed were discussed.

对二级脱盐水系统中铁离子含量超标的原因，如来水水质发生波动、再生剂受到污染、预处理系统操作调整、床体运行切换等进行了论述。
