The invention utilizes fresh water scaleless fishskin for the production of collagen, and has the advantages of simple and fast method, very beneficial effects for the processing level of the waste materials of aquatic products, and great economic benefit.

本发明利用淡水无鳞鱼皮制取胶原蛋白，方法简单快速，对于提高我国农、畜、水产品的下脚料的加工水平是十分有益的，并会产生很大的经济效益。

Vexillifer and Neophocaena phocaenoides is 15.03%(49/326bp). Two phylogenetic trees, constructed by using sequence data, suggest that Lipotes vexillifer does not share a direct common ancestor with Inia geoffrensis, thus provide molecular evidence in favor of the establishment of family Lipotidae; extant river dolphins might be a group ofes with

系统发育分析结果表明：白暨豚与亚河豚没有直接共同的祖先，从而为白暨豚科的建立提供了有利的分子证据；现存的淡水豚类可能仅是外形上相似的物种群，Muizon1984；1988a

The Inter-Institutional Database of Fish Biodiversity in the Neotropics is an international cooperative effort to make available systematic and geographic data on Neotropical freshwater fish specimens deposited in natural history collections in the New World and Europe.

该数据库通过国际上的共同努力使新热带地区淡水鱼类标本的系统数据和地理数据是可获得的。这些标本主要存放于新大陆和欧洲的自然历史收藏品中。

Using a mean age concept defined by Deleersnijder, we apply the three-dimensional hydrodynamic and eutrophication model HEM-3D to investigate the pollutant age distribution under different river discharge conditions in the Pamlico river estuary, North Carolina.

根据Deleersnijder定义的一个平均年龄概念，运用耦合了物质输运模式的一个三维水动力－富营养化数值模型(HEM-3D)，研究了位于美国北卡罗莱纳州Pamlico河口的污染物输运时间在不同淡水流量影响下的分布情况。

Constitution and distribution of freshwater crabs have close relationship with altitude, terrain features, and movements of water in the area. Wild rodent animal may contribute to the maintenance and expansion of the endemic areas of Paragonimus .

淡水蟹类种类的组成与分布与其不同海拔高度和地势地貌及其水系的走向等密切相关；野生啮齿类动物对于并殖吸虫疫源地的维持甚至扩大起着一定的作用。

Siniperca chuatsi and Channa argus are two fish species belonging to the same family Perciformes with the spiny eel, which both possess productive importance. So far there are no any reports about their sex chromosomes.

鮨科鱼种鳜鱼和鳢科鱼种乌鳢都是鲈形目的物种，具有较高的经济价值，是同刺鳅近缘的常见淡水鱼类，目前尚无有关两个物种的性染色体的报道。

The specimens were collected from 4 different origins: 1 Smuggled sturgeons (Nos. 1-15); 2 Aquaculture specimens from Chupei station of Freshwater Aquaculture Research Center, including A. schrenckii (Nos.18, 21-24), A. gueldenstaedtii (No.16), A. sinensis (No.17), A. baerii (No.19) and one unknown species sturgeon (No. 20); 3 A. schrenckii (No.25) and A. transmontanus (No.26) from aquaculture pond in Fu-San; and 4 Polyodon spathula (No.27) and unknown species sturgeons (Nos.28-31) from Taipei city Zoo.

研究材料取自四个地点：1海巡署在云林箔子寮港查获的走私鲟(Nos.1-15)，2竹北淡水繁养殖研究中心所饲养的史氏鲟(Nos.18， 21-24)、俄罗斯鲟(No.16)、中华鲟(No.17)、西伯利亚鲟(No.19)、及未知种鲟(No.20)，3福山养鳟场所饲养的史氏鲟(No.25)及高首鲟(No.26)，以及4台北市立动物园所饲养的匙吻鲟(No.27)及未知种鲟(Nos.28-31)。

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。

After this Stop we made on to the Southward continually for ten or twelve Days, living very sparing on our Provisions, which began to abate very much, and going no oftner into the Shoar than we were oblig'd to for fresh Water; my Design in this was to make the River Gambia or Sennegall, It is to say, any where about the Cape de Verd, where I was in hopes to meet with some European Ship, and if I did not, I knew not what Course I had to take, but to seek out for the Islands, or perish there among the Negroes.

这次停船之后，我们向南一连行驶了十一二天，我们的粮食逐渐减少，只得省着点吃。除了取淡水不得不上岸外，很少靠岸。我这样做的目的是要把船驶到非洲海岸的冈比亚河或塞内加尔河；也就是说，到达佛得海角一带，希望能在那儿遇上欧洲的商船。万一遇不到的话，我就不知道该往哪儿去了。那就只好去找找那些群岛，或者死在黑人手里了。

Hike to the island-s deepest lake, Lake Wabby, surrounded by a massive sand-blow and small, scenic Lake Allom where fresh-water turtles lie on the forest-fringed shore.

远足前往岛上最深的湖瓦比湖和小巧秀丽的艾勒姆湖。瓦比湖由巨大的滚动沙丘所包围，而在艾勒姆湖则可以在毗邻森林的岸上看见淡水龟。

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。
