Through seawater pCO_2 time series observations along with the surface water chemistry, we observed significant diurnal changes of surface pCO_2 ranging from -10μatm in the oligotrophic SCS, 50-150 uatm in Xiamen Bay and Shenhu Bay, up to as high as 600μatm in the coral reef system at Xisha Islands. Processes that modulate the pCO_2 diurnal variations are significantly different between sites, which can be grouped into three categories: temperature control, tide / current control and biological control.

我们的实验结果表明，所有观测区域均表现出显著的pCO_2周日变化，变化幅度从-10μatm到600μatm不等，其中，南海北部寡营养盐开阔海域的pCO_2变化幅度约为10μatm，以厦门湾、深沪湾为代表的海湾河口区域的pCO_2变化幅度为50-150μatm，而西沙群岛珊瑚礁生态系统的pCO_2的周日变化幅度高达600μatm以上。

In late September and early October 2002, 163 surface samples were grabbed from the Yangtze subaqueous delta within a range of 122°~123°E and 30°50'~31°50'N. Based on analyses of grain size, foraminifera, ostracoda, carbonate, organic carbon of surface sediments, the study area can be divided into two parts, i.

2002年9-10月在长江水下三角洲获取了163个表层样，综合粒度、有孔虫、介形类、有机碳以及CaCO3含量的资料表明，研究区明显分为两部分，即长江河口现代三角洲和晚更新世末期三角洲。

According to the nature of the water sources, wetlands can be classified into six types: marine, estuarine, lacustrine, riverine, palustrine (found in marshes, swamps and bogs) and artificial.

按水源界别，湿地可分为六大类：海洋、河口三角洲、湖泊、河滨、淡水（位於沼泽、草泽及苔地的湿地）和人工湿地。

Wetlands could be classified into 6 types that they are marine, estuarine, lacustrine, riverine wetlands along rivers and streams, palustrine (wetlands in marshes, swamps and bogs and artificial.

湿地可分为6大类──海洋、河口三角洲、湖泊（包括与湖泊有关连的湿地）、河滨（包括与河溪相关连的湿地）、淡水（包括位於沼泽、草泽及苔地的湿地）和人工湿地。

Using a mean age concept defined by Deleersnijder, we apply the three-dimensional hydrodynamic and eutrophication model HEM-3D to investigate the pollutant age distribution under different river discharge conditions in the Pamlico river estuary, North Carolina.

根据Deleersnijder定义的一个平均年龄概念，运用耦合了物质输运模式的一个三维水动力－富营养化数值模型(HEM-3D)，研究了位于美国北卡罗莱纳州Pamlico河口的污染物输运时间在不同淡水流量影响下的分布情况。

PAHs source analysis suggested that, in the Yangtze Estuary, PAHs at locations far away from cities were mainly from petrogenic sources.

上海市主要水体(长江口、黄浦江和苏州河口)表层沉积物中总PAHs浓度为107～7，177ng/g-dw。

Ratios of AN/and Flur/calculated suggested that PAHs in Qiantang River were mainly from petrogenic origin and the contribution of petrogenic PAHs was decreasing during the last two years.(2)The input and output of PAHs in estuary section of Qiantang River were 21.83 t/yr and 13.49 t/yr,respectively.The input of PAHs was higher than output of PAHs,which caused the increase of concentrations of PAHs in Qiantang River.

2钱塘江河口段15种PAHs的输入通量约为21.83 t/yr，其中干沉降输入约为0.41 t/yr，湿沉降输入约为0.78 t/yr，地面径流输入约为8.50 t/yr，上游输入约为12.14 t/yr，下游输出通量约为13.49 t/yr，输入输出通量之差为8.34t/yr，输入通量高于输出通量，导致水体中PAHs浓度逐年升高。

However, surfing the Pororoca is especially dangerous, as the water contains a significant amount of debris from the margins of the river.

然而，在河口高潮冲浪是尤其危险的，因为波浪中夹杂着大量从河边带来的残骸碎片。

The record that we could find for surfing the longest distance on the Pororoca was set by Picuruta Salazar, a brazilian surfer who, in 2003, managed to ride the wave for 37 minutes and travel 12.5 kilometers.

我们能在数据中找到的在河口高潮做过最长距离冲浪记录的人是由一名巴西的冲浪选手Picuruta Salazar在2003年创造的，他在波浪上坚持了37分钟，并行进了12.5千米的距离。

Inspired by the famous Firth-of-Forth Bridge in Scotland, the three towers are constructed from one load-bearing skin which is geometrically based on small oceanic creatures called 'radiolaria'.

灵感来自的著名的河口，第四在苏格兰，三塔从一个承载皮肤是几何级数的所谓'小海洋生物为基础构造的桥放射虫'。

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
