淡水的

C Caddis - one of the three most important aquatic insects imitated by fly fishermen; found world wide in all freshwater habitats; adult resembles a moth when in flight; at rest the wings are folded in a tent shape down the back; the most important aquatic state of the caddis is the pupa, which is its emerging stage (also see larva, pupa and emerger).

是三种非常重要的经常被钓鱼者使用的水生昆虫之一，世界各地的淡水栖息地都有，成虫飞动的时候象飞蛾，静止的时候翅膀象后向下叠起成帐篷状。Caddis最重要的水生态是pupa，是蜕皮阶段。

At the present, the water saving system for farming Corbicula fluminea is exploited and used. The concept of water saving system is purifying the water quality by using ecology engineering, and reused the water for farming Corbicula fluminea. This study is to investigate the effect of the water saving system by ecology survey, and to understand the feeding ecology of the freshwater clam.

近年来，为因应淡水资源的不足，开始有采用所谓的节水养殖系统来养殖台湾蚬，主要概念采用生态平衡的模式工法来净化水质而得重复利用，本研究主要即利用调查蚬池的水质及生物变化，来了解节水养蚬系统的功效，同时探讨台湾蚬的滤食情形并作为一般水质优氧化处理之参考，来了解台湾蚬的滤食情形。

However,very low Mn contents(average 19.8ppm),relatively high Sr contents(average 137ppm)and the homogenization temperatures measured in fluid inclusions of crystalline dolomite do not support the hypothesis that meteoric water as high as 94% involved the dolomitization.

但极低的锰含量、相对较高的锶含量和包裹体均一化温度等资料均不支持有94%的大气淡水参与了结晶白云岩的白云石化作用，其白云石化流体应是埋藏成岩过程中囚禁的近同期、但是非同期的海源流体，其来源可能与埋藏成岩过程中该时间段蒸发盐的溶解有关。

It was a dismal Sight to look at: The Ship, which by its building was Spanish, stuck fast, jaum'd in between two Rocks; all the Stern and Quarter of her was beaten to pieces, with the Sea; and as her Forecastle, which stuck in the Rocks, had run on with great Violence, her Mainmast and Foremast were brought by the Board; that is to say, broken short off; but her Boltsprit was found, and the Head and Bow appear'd firm; when I came close to her, a Dog appear'd upon her, who seeing me coming, yelp'd, and cry'd; and as soon as I call'd him, jump'd into the Sea, to come to me, and I took him into the Boat; but found him almost dead for Hunger and Thirst: I gave him a Cake of my Bread, and he eat it like a ravenous Wolf, that had been starving a Fortnight in the Snow: I then gave the poor Creature some fresh Water, with which, if I would have let him, he would have burst himself.

眼前的景象一片凄凉。从那条船的构造外形来看，是一条西班牙船，船身被紧紧地夹在两块礁石之间。船尾和后舱都被海浪击得粉碎，那搁在礁石中间的前舱，由于猛烈撞去，上面的前桅和主桅都折断倒在了甲板上，但船首的斜桁仍完好无损，船头也还坚固。我靠近破船时，船上出现了一只狗。它一见到我驶近，就汪汪吠叫起来。我向它一呼唤，它就跳到海里，游到我的小船边来，我把它拖到船上，只见它又饥又渴，快要死了。我给了它一块面包，它就大吃大嚼起来，活像一只在雪地里饿了十天半月的狼。我又给他喝了点淡水，它就猛喝，要是我不制止它的话，真的可以喝得把肚子都涨破。

In this paper, the characteristics of the wetland ecosystem of the Poyang Lake national nature reserve are discussed through considerations of the hydrography, soil, biological composition and system function.

鄱阳湖是我国最大的淡水湖。鄱阳湖自然保护区以其独特的地形地貌，在亚热带湿润季风气候综合作用下，形成了一个多功能的复合湿地生态系统。根据湿地三条划分标准：有充分的水分、有机质含量较高的土壤及适应于此环境的植被。鄱阳湖自然保护区属淡水湿地生态系统。

Dinomastigota A phylum of the Protoctista containing mainly single-celled marine or freshwater algae that swim in a twirling mannerly by means of two UNDULIPODIA that lie at right angles to each other in two grooves within the organism ' s often stiffened by cellulose plates under the cell membrane.

腰鞭毛虫门：原生生物中的一门。主要包括单细胞的淡水以及海洋藻类。它们可以通过在生物体壁表面两条沟内的两个相互成直角的波动足通过旋转的方式在水中游泳。体壁可以被细胞膜下的纤维素板所加厚。

To catch deep-water walleyes, slowly back troll a weighted jig-and-minnow combination or in warmer water also try a jig with a night crawler or leech, a plastic grub, empty jigs, minnows, night crawlers, crawfish tails, leeches, or a V-shaped cut of yellow perch belly.

若要听深水 walleyes 慢慢地重新特罗尔加权的夹具 minnow 组合或较正常温暖的水中也尝试一夜履带式或水蛭、塑胶的食物、空夹具、 minnows、夜 Crawler、淡水小龙虾尾、 leeches，或的黄色鲈鱼腹部的 V 型切割的钻。

On their own, they make music out of the sounds of objects, animals, people and actions such as amplified crayfish nerve tissue, liposuction surgery, a steel guitar recorded in a sewer, dogs barking, the sound of a frozen stream thawing in the sun, etc.

而他们自己的乐队则是使用物体、动物、人以及行为的声音来制作音乐，比如被放大的淡水鳌虾神经系统的反应，吸脂手术，下水道中的夏威夷吉他，狗吠，还有冰封溪流在太阳下融化的声音等等。

It used to happen naturally with the Nile's seasonal floods; after the completion of Egypt's High Dam in 1970 (one of the most ambitious engineering projects on earth), these seasonal floods came to an end, but a vast network of irrigation canals continued to bring gallons of freshwater to the people who worked the land, the fellahin , ensuring salinity levels remained low.

过去，这一使命自然而然地要由尼罗河的季节性洪水来完成。但是，1970年后，埃及大水坝的竣工（世界上最宏伟的工程项目之一）为这种季节性洪水划上了句号。但是，巨大的灌溉网络继续将大量的淡水送到在田间工作的人--农民的身边，从而使土壤盐度仍然维持在低水平上。

The nautre of ester bond and sedimentary medium condition control the distribution pattern of organic acid ester in strong reductional environment and water-washed oxidized crude oils. The former features higher contents both of 9, 11-Octadecadienoic acid, methyl ester and Hexadecanoic acid, showing the non-reversible hydrolysis reaction of ester bond in condition of basicity; the later features higher contents of Hexadecanoic acid and Octadeanoic acid, and lower contents of nonsaturated and side-chain acid ester, indicating the reversible hydrolysis reaction of ester bond in acid condition.

酯键的化学性质和沉积环境中介质条件，决定了强还原咸水盐湖相和淡水湖沼相经水洗氧化次生变化的原油有机酸酯的分布特征，前者9，11-十八二烯酸甲酯与正十六烷酸为主，反映酯键在碱性条件的不可逆水解过程，后者以正十六烷酸和正十八烷酸为主，烯酸和支链酸很少，反映酯键的酸性条件的可逆性水解，烯酸经氧化向正十八烷酸，正十六烷酸转化。

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。
