淡水

Based on the field experiment data of winter wheat blending irrigation by saline water in Nanpi Ecological Agriculture Experimental Station of the Chinese Academy of Sciences from 2002 to 2005, the effects of blending irrigation with mineralization of 0.84, 3, 4 and 5 g/L on the soil salification rate, soil sodium adsorption ratio of soil saturation extract as well as winter wheat yield and yield constitute factors irrigated were studied in order to determine upper limit of irrigation mineralization suitable for the location.

根据中科院南皮生态农业试验站2002～2005年的冬小麦微咸水混灌田间试验资料，以淡水为对照研究了矿化度分别为3、4、5 g/L的微咸水混灌对土壤积盐率、土壤饱和浸提液钠吸附比、冬小麦产量和产量构成因素以及水分利用效率的影响，从而确定适宜的灌溉水矿化度上限。

If sea levels rise as scientists predict, coastal regions may see increased salination of aquifers -- natural underground reservoirs -- which will affect access to fresh water in those areas, Greenblatt said.

葛林布莱特说，正如科学家所预测的那样，沿岸地区可能会看到更多盐化含水层-天然地下水库，这将影响到这些领域中淡水的获取。

A mass of experiments validated that exploitation and rational utilization of saline shallow groundwater, declining the water level to an optimal depth to reducing water invalid evaporation can increase amount of water resources and storage capacity of aquifer, prevent waterlogging or drought, improve groundwater salinity and control the process of soil salination, improve the eco-environment, alleviate the threat for the resource of fresh water.

大量的实验证明，合理开发利用浅层咸水，使咸水水位降低到合理水平，可以：避免地下水的无效蒸发，增加水资源量；增强调蓄能力和抗早防涝能力；促进浅层咸水淡化，改造盐碱地，改善生态环境；减轻对淡水资源的威胁。

Total range of salinity of the algal ecotopes is 0. 2-44. 9g/L, but most of the species develop in fresh or slightly saltish water with salinity not exceeding 1-5(8)g/L.

轮藻植物生长的盐度范围为0.2-44.9g/L，一般生长于盐度不超过1-5(8)g/L的淡水或微咸水环境。

The invention relates to a collagen preparation method by utilizing fresh water scaleless fish-skin and alkali, which belongs to the technical field of aquatic product processing.

一种利用淡水无鳞鱼皮碱法制备胶原蛋白的方法，属于水产品加工技术领域。

In hydroponics of different combination of fresh and sea water, the length of internode, stem girth ,the content of leaf dry matter, leaf chlorophyll, protein, soluble sugar, proline, malondialdehyde, catalase and peroxidase and the activity of root activity in Sesuvium portulacastrum.were detected and analysized.

主要研究结果如下： 1、在全淡水、2：1淡/海水、1：2淡/海水和全海水四种不淡/海水组合水培条件下，检测了海马齿节间长度、叶片干物质含量、叶片叶绿素含量、蛋白质含量、可溶性糖、脯氨酸含量、茎周长、丙二醛含量、过氧化氢酶及过氧化物酶、活性根系活力等11个与耐盐碱有关的形态和生理指标并进行了相应的分析。

Four kinds of mangrove plants,\%Kandelia candel,Bruguiera gymmnorrhiza,Aehiceras Cirniculatum,Sonneratia apetala \%were selected for taming in fresh water for eight months.

选择秋茄、木榄、桐花树、无瓣海桑4 种红树林植物的幼苗，在中山大学附属中学校园内进行了8 个月的池塘和陆地的淡水驯化试验。

Lastly, the sweetwater was there.

最后的一个有利条件是：附近有淡水。

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.
