河段

The model can be used to forecast not only the date of ice run,freeze-up and break-up but also the temperature of water,ice flow density,ice jams as well as ic...

理论分析和实例论证都表明该神经网络模型能够进行宁蒙河段冰情预报。

The variety of the water level during the period the ice jam is one of the phenomena that forming mostly in the ice jam segment.

这些地区河流冬季常形成冰盖、冰塞或冰坝，它们会带来各种冰凌灾害。冰塞期间水位的变化是冰塞河段最主要的现象之一。

The concentrations of total nitrogen and nitrate in Miyun Reservoir were lower than that in its influents.

密云水库的总氮、硝态氮含量全年几乎都低于三条河流，其中潮河的总氮、硝态氮含量最高，其次是白河，最低的是清水河；三条河流入库河段的总氮和硝态氮含量变化特征为植物生长季较低，非生长季较高。

The current of the Niagara Falls rushs down cliff to come downstream and new confluent later, continue to roll in gorge buckjump, the with prep above cataract velocity of flow on the reach that in inadequacy 2 kilometers grow is horary the fall that 35.4 kilometers drop to swing and issue 15.8 meters, deduce a world to go up the maddest the the wild, most horrible, most dangerous eddy race, rush again deep the eddy pool of 38, next dragon of a flood dragon turns over, the elder brother that passes east bank Canada this, the Liweisidu of right bank United States, had rushed " devil hole race ", along final " Liweisidu affluent gorge " by enter eastwards on the west install rude lake.

尼亚加拉瀑布的水流冲下悬崖至下游重新汇合之后，在峡谷里继续翻滚腾跃，在不足2公里长的河段上以高于大瀑布的流速每小时35.4公里跌荡而下15.8米的落差，演绎出世界上最狂野。最恐怖。最危险的漩涡急流，又冲进深38的漩涡潭，然后一个蛟龙翻身，经过左岸加拿大的昆斯顿。右岸美国的利维斯顿，冲过&魔鬼洞急流&，沿着最后的&利维斯顿支流峡谷&由西向东进入安大略湖。

As the worst drought since 1988 has stressed crops across parts of the Midwest, low-water levels are turning parts of the Mississippi and Ohio rivers into virtual sandbars, causing towboats and barges to run aground and delaying shipments of some agricultural goods.

由于中西部部分地区遭受了1988年以来最严重的干旱，密西西比河和俄亥俄河的部分河段因水位低而正在成为沙洲，致使拖船和驳船搁浅，部分农产品运输延误。

Shrinking lakes and rivers, the Yellow River drying up in the Yellow River from 1972 to the beginning of 1998 there disconnection of the 27 years, the Yellow River Lijin station stop in a total of 21, reached four years of stop-off frequency, for a total disconnection 1,050 days, the average Each year 50 days disconnection, 1997 devascularization 226 days, up to 704 km river drying up of the lower reaches of the chief of 90%.

河湖萎缩，黄河断流黄河从1972年开始出现断流到1998年的27年间，黄河利津站共有21年发生断流，断流频率已达四年五断，共计断流1050天，平均每个断流年份50天，其中1997年断流226天，断流河段长达704公里，占下游河段总长的90%。

The model divides the research area into five water balance modules: river module, spring-well module, reservoir-lake module, agriculture area module and non-agriculture area module, and the water exchanges between these modules are made through surface channel and groundwater movement.

模型把研究区划分为河段、泉井、水库湖泊、农区和非农区五类水均衡模块，水均衡模块之间通过地表渠系、地下水侧渗进行水量交换。

Since China started the new Pearl River Bridge (six two-way carriageway, within the loop Guangfu radiation engineering, bridge building, exchange of strings), the next year recruiting students of the National Model High School --- Guangzhou 1 Zhongshan University Tansha new site, has now embryo of the river "spot zone" three projects, big Tansha island transport network will show a "sea" three-dimensional structure, and supporting education, environmental management, integrated governance also have "changed face," and there are Liwan investment is transforming the north-south axis on the island bridge builder ----(two-way four lane), the new scheme people at the district level hospitals, district of 113 million yuan a "Tianlu" project (construction Green Square, along the Green Belt) Tansha Island makes big tourist scenic sections of the Pearl River in Guangzhou's largest island fast becoming hot spot for investment, early Liwan District American business in Hong Kong will focus on the recommendation of the Great Tansha Island, Macau has many investors concerned.

加上去年中开始动工的新珠江大桥（双向六车道、内环路广佛放射线工程、桥中建互通式立交）、明年即对外招生的全国示范高中---广州市一中大坦沙新校址、已现雏形的沿江&亲水区&三大项目，大坦沙岛的交通网络将呈现&海陆空&立体架构，而教育配套、环境整治、综合治理等亦纷纷&变脸&，还有荔湾区正在投资改造的岛上南北轴----桥中路、计划新建的区级人民医院、区里1.13亿元启动的&添绿&工程（建绿化广场、沿江绿化带等），使得大坦沙岛这个广州珠江旅游风景河段上最大的岛屿迅速成为投资热土，年。。。。。。
