水面

For the water we use Maya's Ocean Shader to create animated water that integrates perfectly into our scene, including reflection of the backplate and shore/pier intersection through the use of camera projections.

对于水面效果，我们使用了Maya的海洋材质去创建动态的水面效果，完美的结合到我们的场景当中去。

A little after Noon I found the Sea very calm, and the Tyde ebb'd so far out, that I could come within a Quarter of a Mile of the Ship; and here I found a fresh renewing of my Grief, for I saw evidently, that if we had kept on board, we had been all safe, that is to say, we had all got safe on Shore, and I had not been so miserable as to be left entirely destitute of all Comfort and Company, as I now was; this forc'd Tears from my Eyes again, but as there was little Relief in that, I resolv'd, if possible, to get to the Ship, so I pull'd off my Clothes, for the Weather was hot to Extremity, and took the Water, but when I came to the Ship, my Difficulty was still greater to know how to get on board, for as she lay a ground, and high out of the Water, there was nothing within my Reach to lay hold of; I swam round her twice, and the second Time I spy'd a small Piece of a Rope, which I wonder'd I did not see at first, hang down by the Fore-Chains so low, as that with great Difficulty I got hold of it, and by the help of that Rope, got up into the Forecastle of the Ship; here I found that the Ship was bulg'd, and had a great deal of Water in her Hold, but that she lay so on the Side of a Bank of hard Sand, or rather Earth, that her Stern lay lifted up upon the Bank, and her Head low almost to the Water; by this Means all her Quarter was free, and all that was in that Part was dry; for you may be sure my first Work was to search and to see what was spoil'd and what was free; and first I found that all the Ship's Provisions were dry and untouch'd by the Water, and being very well dispos'd to eat, I went to the Bread-room and fill'd my Pockets with Bisket, and eat it as I went about other things, for I had no time to lose; I also found some Rum in the great Cabbin, of which I took a large Dram, and which I had indeed need enough of to spirit me for what was before me: Now I wanted nothing but a Boat to furnish my self with many things which I forsaw would be very necessary to me.

午后不久，海面风平浪静，潮水也已远远退去。我只要走下海岸，泅上几十米，即可到达大船。这时，我心里不禁又难过起来。因为我想到，倘若昨天我们全船的人不下小艇，仍然留在大船上，大家必定会平安无事。这时就可安抵陆地；我也不会像现在这样，孤苦伶仃孑然一身了。而现在，我既无乐趣，又无伴侣。想到这里，我忍不住流下泪来。可是，现在悲伤于事无济，我即决定只要可能就先上船去。当时，天气炎热，我便脱掉衣服，跳下水去。可是，当我泅到船边时，却没法上去，因为船已搁浅，故离水面很高；我两臂所及，没有任何可以抓住的东西。我绕船游了两圈，忽然发现一根很短的绳子。我惊异自己先前竟没有看见这根绳子。那绳子从船头上挂下来，绳头接近水面；我毫不费力地抓住绳子往上攀登，进入了船上的前舱。上去后发现船已漏水，舱底进满了水。因为船搁浅在一片坚硬的沙滩上，船尾上翘，船头几乎都浸在水里，所以船的后半截没有进水。可以想像，我急于要查看一下哪些东西已损坏，哪些东西还完好无损。首先，我发现船上的粮食都还干燥无恙。这时，我当然先要吃些东西，就走到面包房去，把饼干装满了自己的衣袋，同时边吃边干其他活儿，因为我必须抓紧时间才行。我又在大舱里找到了一些甘蔗酒，就喝了一大杯。此时此刻，我极需喝点酒提提神。我这时只想有一只小船，把我认为将来需要的东西，统统运到岸上去。

When the reservoirs are communicating, the water level should be the same (unless there's a closed chamber with some air trapped underwater, such as a diving bell).

因为连通器的水面高度应该都一样，除非有些水面是封闭的东西，比如游泳池。

Every day Finny would swim along the ocean floor dreaming of what it would be like to be above the water.

他在想他有没有一天可以在水面上看看。。水面上的世界。他问他妈妈说。。

此外，在讯号分析部份除了针对水面高程进行分析之外，我们也分析GPS反射讯号的都卜勒频移值，利用速度场转换的方式可计算出每个反射点的流速，而在此利用GPS反射讯号与数值地形资料库整合应用，透过整合系统的开发将可提供全面性及近即时性的河川水面高程及流速的量测，更可加以估算河川洪水期之河水流量，用以提供河川洪峰流量之监控。

The effect of groyne length and layout on water surface is analyzed in the paper. Based on the results of simulation and experiment, the local energy loss of the flow due to the groyne is studied. Consequently the surface variation and height of damming are also analyzed.

实验研究包括单丁坝及双丁坝条件下丁坝影响区内流场及水面变化规律；数学模拟方面包括二维和三维自由水面追踪及流场数学模型开发、验证和应用。

Considering the difference of runoff characteristics on different underlying surface in the area of plain tidal river network, four kinds of surface is divided,namely, waters paddy field-, dry land and central urbanized area,and suitable method is adopted separately in each surface to simulate runoff process. Xinanjiang Model usually applicable for mountain areas is introduced to river network area, furthermore, the paper researches runoff calculation of central urbanized area, the underlying surface is divided into pervious and imperviousness areas.In perviousness areas, Hoton Infiltration formula and corresponding spatial infiltration rate curve are used to establish the relationship between infiltration rate and soil moisture in order to decide the infiltration. According to practical situation.

根据平原河网区城市下垫面产汇流方式的不同，分成水面、水田、旱地、城镇四类，分别采用相对应的产流汇流计算方法，将适用于山丘区的新安江模型引入到平原河网区城市，同时对于城镇这类下垫面，从下渗角度考虑，划分成透水和不透水两种类型，根据霍顿下渗公式和下渗率空间分布曲线，建立下渗率和土壤含水量的关系，进而研制出城镇透水面的产流计算方法，城镇汇流根据实际情况可结合城市管道排水计算。
