淡水生物

For a man who commits to Buddhism and fast,he surely gains little sense of happiness in the face of Peking roast duck which is renowned home and abroad, because it's not what he want to have,at the moment all that he desires to have might be merely two loads of steamed bread and a dish of fried bean sprout. For an old man living alone in the countryside,though he always receives money and clothes from his son residing in the town,which makes the villiagers envy him very much,he would rather enjoy the happiness of being with his children.For a man runs errands in the burning sun,he is badly in need of a patch of shade,a swirl of cool breeze,a fan,or a spring of cool water,he wants anything but a luxurious mink coat.Abundant as the sea is with various species and countless treasure,for a sailor,the seemly trivial freshwater is most wanted on the voyage.

一个吃斋念佛的饥饿的人，面对着驰名中外的北京烤鸭，是不会有幸福感的，因为那不是他需要的，他急需的，可能只是两个馒头，一盘素炒豆芽而已；独自住在乡下的老人，总是能收到城里儿子寄来的钱物，很让乡亲们羡慕，但老人最想要的不是这些，而是儿孙膝下承欢的天伦之乐；在炎炎烈日下赶路的人，急需的是一片树阴，一阵凉风，一把扇子，一眼清凉的泉水，而不是一件名贵的貂皮大衣；大海是富饶的，它哺养了各种各样的生物，珍藏着无数的宝藏和财富，但在海上远航的人，急需的却是普普通通的淡水。

To understand the integrated effects of organic matter loading on the benthic chemical properties, microbial communities, and benthos in an estuarine system, two field studies and a set of laboratory experiments were conducted.

以台湾为例，约有三分之二的河川呈现中度或严重污染，而北部最大河川淡水河由於承受大量生活污水的排放，使得像文蛤Meretrix lusoria这类生存在河口的生物受到严重影响。

The structure and organization of mitochondrial genomes of 14 marine bivalves and two freshwater bivalves were analyzed using comparative genomics and bioinformatics methods.

Efficiency:It uses Zhu Ji pearl fresh water and hydrolyzes into power,which maintains effective ingredient to the further extend.It can provide abundant water to skin,and its butterfat,vitamin and minerals can be easily absorbed by your skin.

功能：本品采用诸暨淡水珍珠以生物水解成粉，最大程度保留了珍珠的有效活性成分，水嫩白珍珠粉不单可以给肌肤充分的水份，它所含有的乳脂肪，维他命以及矿物质也很容易被你的肌肤所吸收。

Large coarsely spiral bacteria; free-living in fresh or salt water or commensal in bodies of oysters.

大型质地粗糙的螺旋形细菌；自由生活与淡水或海水中，或者牡蛎体内的共生物。

The results showed that the main factors affecting the distribution of inorganic nitrogen were coastwise fresh-water runoff and biotic activities, and the former was more important. The analysis by N/P ratio showed that N was a limited factor on the primary productivity in autumn and winter, but P was in spring and summer.

结果表明，影响北海湾无机氮含量分布的主要因素是沿岸冲淡水，其次是生物活动；通过N/P值分析，表明了N为该湾秋冬季节初级生产力的限制因子，而P则为该湾春夏季节初级生产力的限制因子。

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。

The scope of research activities in this society covers the ancient mollusca and recent species (including terrestrial, freshwater, medical and marine molluscs), involving the areas as follows: ancient species evolvement and environmental variance, morphology, floristics, biological diversity and protection, genetics and breeding and the security concerning, pathology, aquaculture and ecological environments, etc.

中国贝类学的研究范围涵盖古贝类和现生贝类（陆生贝类、淡水贝类、医学贝类和海产贝类），涉及的研究方向有：古贝类进化与环境变迁，形态、区系、生物多样性及其保护，遗传育种及其安全性，病害，养殖与生态环境等，取得了丰硕的研究成果，促进了我国贝类学理论和相关技术的应用与发展。

Darwin discussed about some anomalous forms in fresh water basins, which belong to the remnants of some interesting orders. Because these anomalous forms exhibit the anomaly of geographical distribution e.g. Ganoid fishes, or morphological anomaly such as Ornithorhynchus and Lepidosiren , they may be called living fossils. It is believed that Darwin presented the facts of the above anomalous forms, and used the term "living fossil" in order to further illustrate the subject of "Circumstances Favorable for the Production of New Forms Through Natural Selection" in Chapter IV. The term "living fossil" appears on page 486 again in the last Chapter, i.e. Chapter XIV "Recapitulation and Conclusion", where Darwin emphasized the significance of so-called "living fossils".

第一次在该书第四章&自然选择&（第107页）：为了在该章深刻阐述&通过自然选择产生生物新类型的有利条件&这一主题，达尔文谈到了淡水流域中残存着地理分布或形态上很异常的一些生物，如：硬鳞鱼、鸭嘴兽和美洲肺鱼，可以称之为&活化石&；第二次是在该书最后一章&复述与结论&（第486页），达尔文对&活化石&的作用进行了小结。

This study examines the criteria of water temperature for black carp, grass carp,silver carp, bighead, common carp, etc in the condition of thermal shock.The paper reported the optimum growth temperatures,the maximum lethal temperatures and the short exposure maximum high temperatllres for these fishes.All the criteria can be considered as appraisal values of water temperature for thegrowth and breeding of these fishes.

为保护水域生态环境的平衡，合理利用水资源和为制定发电厂热水排放的温度标准，提供有关水生生物的温度基准值，对青鱼、草鱼、鲢、鳙和鲤等七种主要淡水经济鱼类作了温度基准值的研究，提出了最适生长温度，最大致死温度及短期暴露最大高温等基准值，以作为确保水生生物能正常生长与繁殖情况下，环境温度的评价标准。

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。
