Fourthly, taking three groups of water quality data of Jinhe River as original data, prediction to water quality of the river was made. Compared with real monitored value, the error of predicted value of all of simulating terms, including dissolved oxygen, bio-chemical oxygen demand, chlorophyll a, organic nitrogen, ammonia nitrogen, nitrite nitrogen, nitrate nitrogen, organic phosphorus, dissolved phosphorus and temperature, were basically within error limit of 20%, which validated the validity of the model.

第四，以津河三组水质数据为原始数据，通过建立的模型对津河水质进行预测，水质变量溶解氧、BOD、叶绿素、有机氮、氨氮、亚硝酸盐氮、硝酸盐氮、有机磷、溶解性磷和温度的预测值与实际监测值均在所设定的误差范围20%之内，验证了模型的有效性。

Leaving the water-side, where rushes stood thick and tall in a stream that was becoming sluggish and low, he wandered country-wards, crossed a field or two of pasturage already looking dusty and parched, and thrust into the great sea of wheat, yellow, wavy, and murmurous, full of quiet motion and small whisperings.

河岸边，灯芯草丛已经长得又高又密，河水已经流得缓慢，水位低落了。河鼠离开了河岸，漫无目地的朝田野走去。他走过一两块龟裂的布满尘埃的牧场地，一头钻进一大片麦田。麦子金黄灿灿，麦浪翻滚，沙沙作响，充满了宁静的动作和呢喃细语。

Early in the new year of 1951 Recce Troop fought a valuable action on the Han River but lost twenty three killed or missing. In February the UN Forces took the offensive, helping the Gloucesters capture Hill 327, and by April patrols were probing north of the Imjin River seemingly uncontested until a massive enemy assault on the 22nd.

最初于1951年新年的时候，该部队（Recce Troop在汉河参与了一次真正意义的战斗，结果被歼23人。2月份，联合国军发动攻势，该部队帮助the Gloucesters攻占327号山，4月部队进行Imjin河以北的巡逻及侦察的任务，他们一直无所作为直到22日遭遇大股敌军袭击。

The Mississippi riverboat, which evolved from simpler steamship of the early 1800's, became the dominant form of passenger transport on the Mississippi River.

需要注意的是，transport这里作名词，有"运输工具"的意思参考译文：密西西比河船，在1800从简单的汽船演变过来，成为密西西比河上重要的旅客交通形式。

The deltas differ from typical deltaic model.Deltaic front subaqueous distributary channel sand bodies and deltaic plain distributary channel sand bodies are the skeleton sand bodies of meandering stream-shallow sea delta and braided streain-shallow lake delta respectively but not tranditional deltaic front river mouth sand bars.

这两类三角洲与经典的三角洲模式不同的是，三角洲前缘水下分流河道砂体和三角洲平原分流河道砂体分别构成了曲流河浅水海相三角洲和网状河浅水湖泊三角洲的骨架砂体，而不是传统认为的三角洲前缘河口砂坝。

Some of the best farmland of the Fertile Crescent is in a narrow strip of land between the Tigris and Euphrates Rivers.

肥沃的新月上的一些最佳的农田位于底格里斯河和幼发拉底河之间的狭长地带。

He proposed in the Potomac River and castilla A Naka River Interchange to build a new capital. In 1790, the U.S. Congress, Mr North and South factions after a heated debate to reach a compromise, in the south and the north of the natural dividing line - a Potomac River to draw about 200 square kilometers, the establishment of the District of Columbia, the federal government will be directly under the , To set up the new capital.

他提议在波托马克河与阿纳卡斯蒂亚河交汇处兴建一座新的都城。1790年，美国国会南北方两派议员经过激烈的辩论后达成妥协，在南北方的天然分界线——波托马克河畔划出一块约200平方千米的地方，成立哥伦比亚特区，直辖于联邦政府，在此建立新都。

The luminosity of the most of extraglactic H2O megamaser sources is between tens and hundreds L ⊙, but one of the extragalactic H2O megamaser source TXFS 2226-184 is 6100 L ⊙. It belongs to the class of radio galaxy and is not general. It is mainly caused by its wide spectral profile.

多数河外H2O超脉泽源的光度在几十至几百个 L ⊙之内，但TXFS2226－184源的河外H2O超脉泽源的光度达6100 L ⊙，它属于射电星系类型，是主要由于其谱线轮廓较宽所造成的一种例外情况。

This study was analyzed landscape classification in Kashi River by the classification method of landscape ecology and remote sensing.

通过景观生态学的分类方法，结合遥感，对喀什河上的景观进行分类分析，结果表明，喀什河全流域山地景观的优势度显著大于绿洲景观的优势度。

Nov. mainly inhabits those channels such as mahuang channel、gari channel、bori channel、heping channel and dengchi channel. So it belongs to the distribution area extremely narrow type. From May to October 2005 and May to August 2006, 671 specimens collected were used for studies on the reproductive strategies such as reproduction time, spawning type, the ratio and the fecundity, and gonad development and characters of early life history. The main results are as follows: 1.Every year speaking of spawning season the male"s is earlier than female"s slightly.

Nov。仅分布于宝兴河支流东河盐井以上河段，主要分布在蚂蝗沟、嘎日沟、波日沟、和平水域及邓池沟，属于分布区极其狭窄的种类。2005年5月—10月和2006年5月—8月共采集671尾标本，运用常规生物学指标的测定分析法和性腺的组织切片法，以及对成熟亲鱼人工授精获得的胚胎在立体显微镜下活体观察，研究其繁殖期、产卵类型、性比和繁殖力等繁殖策略及性腺发育和早期发育。

In the end, transportation of PAHs in the environmental matrix was preliminarily investigated and discussed according to PAHs data of soils and sediments from a certain region in Shanghai. The result indicated that there are two or more pathways on PAHs transportation in the environmental matrix.

最后，对上海特定地区内PAHs在环境介质中的迁移径途进行了分析讨论，结果表明上海市土壤和沉积物等环境介质中PAHs的迁移存在多种途径。
