从明代刘天和《问水集》、万恭《治水筌蹄》、潘季驯《河防一览》三部治河书中可以看出治理黄运思想从治水防洪、治河通运———河运合一、以河治河———筑堤束水、以水攻沙的变化，是我国治黄史上治河思想的转折时期。

Red east city is in the biggest city toward border land, here industry company is less, do not have industrial pollution basically, city life sewage emits into duck green river directly, because sewage discharge capacity is less, water quality of duck green river did not get too big impact, at present water quality of duck green river is 2 kinds of water quality.

丹东市为中朝边境上的最大城市，这里工业企业较少，基本没有工业污染，城市生活污水直接排入鸭绿江，由于污水排放量较少，鸭绿江水质并没有受到太大影响，目前鸭绿江水质为二类水质。

Based on the water environment spatial data mining and visualization method, the paper presents these main characteristics and innovations:①Measurement of contamination fluxes:A scene-based research strategy is proposed:measurement /water quality analysis→flow field simulation→contamination transformation rule→fluxes scene simulation→temporal-spatial rule analysis.②Serial numerical models of water environment in the Qiantang River:The controlled equations of the flow field model of the main river,united controlled equations of the main contamination fluxes and water quality prediction model at emergent time are set up.③GIS-based water quality and contamination fluxes decision-making assistance system:A water environment database has been set up;based on MapX and C#.net platform,a system has been developed to facilitate visual inquiry,decision-making and graphics export.

长江源冰川的退缩与人为因素关系不大上官冬辉说，短期内，冰川的融水给长江带来了充沛的水量，表面上看，对西北地区似乎是一件好事，但是，这种补给导致江河的径流量季节性不均，冬季的融水提前释放，从而造成春汛夏旱。

The change extent of the water level and the falling extent the imbedded water level is the biggest in Phragmites sustralis－Carex schmidtii community, The reason is likely to be it's near to the river, and have gutters in the peatland which is near the river, which makes the water enter the river easily, and so make the change extent bigger.

水位变化幅度在芦苇－苔草群落中最大，这可能是由于该区距离河流较近，而且人为的在泥炭地与河流相接处挖排水沟渠，使泥炭地中的水更容易的进入河流，使之变化速率较快，变化幅度较大。

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。
