水面

In this paper,dynamic changes of lacustrine water in the Sihu area were analyzed by using remote sensing.

采用遥感方法分析了四湖地区的湖泊水域的动态变化，分析结果表明：该地区 50年代至 80年代初由于大规模围湖造田，致使湖泊水域萎缩相当严重，80年代以后，湖泊水面急剧减少的趋势得到遏制，而 90年代以后，湖泊水面基本处于无显著变化状态。

In this lotus festival,through the display of the potted flowers in the land and the lotus cultivation in the water of four scenics,the designation of plants'exhbition demonstates manifests the theme of the festival——"tremendous ruins lyrical memory,reflected the new Lotus Show"

圆明园在历史上很多水面就有荷花种植，本届荷花节的植物展示设计通过四大景区陆地盆栽展示及水面荷花种植相结合，表现了"沧桑遗址抒情怀，映日荷花展新颜"的节日主题。

Also, it is proved to be monotonic function.

通过引入一个无量纲参数——单位水面宽度，对梯形明渠正常水深的基本方程进行恒等变形，得到了求解单位水面宽度的超越函数，并证明该方程为单调函数。

The starting point in film, a big fish across allows much more from the fishing hook of surface pendency, The coda in film is still the big fish of this father's incarnation, in the moonlight, spare no effort ground to jump a surface, settle a space.

在影片的开端，一条大鱼越过许许多多从水面垂下的鱼钩，静静游向远方；在影片的结尾，还是这条父亲化身的大鱼，在月光中，奋力地跳出水面，定格。

Structural matter drops to hit water with fixed rate phut from certain height, inchoate and main the structure that attacks water process in the light of phut is answered begin research, and press mutation of field of force and Xing Bo to wait to study however to entering the underwater after water less, and add with each passing day as large bridge and marine project much, the construction in these projects and the phenomenon that phut of large construction content also appeared to hit water in use process, like Guangdong 9 rivers big bridge is bumped to break down after collapsing, large area bridge floor falls into surface to wait, the meeting such as mutation of field of pressure of the underwater after this kind of phut hits water and Xing Bo is right all round structural products gives birth to certain influence, evaluate this kind of influence to have real project sense to construction and design.

结构物从一定高度落下以一定速度砰击水面，早期主要针对砰击入水过程的结构响应开展探究，而对入水后水下压力场突变和兴波等却探究较少，而随着大型桥梁和海洋工程日渐增多，在这些工程的施工和使用过程中也出现了大型结构物砰击入水的现象，如广东九江大桥被撞垮塌后大面积桥面落入水面等，这种砰击入水后水下压力场突变和兴波等会对四周结构物产生一定影响，评价这种影响对施工和设计具有现实的工程意义。

Since reform is developed, our city fishery had great progress, raised face of fish and water and aquatic product crop to all have especially grow substantially, the pisciculture surface 1997 and aquatic product output grew 820 than 1978 respectively times with 148 times.

改革开发以来，我市渔业有了长足发展，非凡是养鱼水面和水产品产量均有了大幅度增长，1997年的养鱼水面和水产品产量分别比1978年增长了820倍和148倍。

The arable land area was increased a lot and garden plot area a little. The original pond was changed to the piscina. The graveyard area, the land area occupied by the use of farmland irrigation and road was reduced.

Just have fish sons jump over out water surface now,big pearls are small dance as pearl assured source of life jade plate on water surface , are so pleasantly surprised that river shoreside this is every child, having opened a mouth wider , even saliva needing to have shed out.

此时，便有一群群鱼儿跃出水面，在水面上大珠小珠落玉盘般的舞蹈，惊喜得这河岸边一个个小孩子，都张大了嘴巴，连口水都要流出来了。

In the same time it puts forward some different water surface wave models and focus on the regular wave model.

它包括三维地形建模和三维水面波浪模型的建模，水面波浪的模拟则是其中的一种。

The paper has studied and analyzed the ship target on water surface detailedly.

本文详细研究和分析了水面船舶目标的特点，针对船舶是人造目标，船体上布满了有棱有角的结构，在图像中存在众多的长直线边缘的特点，提出了使用角点和线段特征的检测方法，并根据水面和船舶的不同反光特征，实现了一种基于关系稳定性的船舶区域分割算法。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
