查询词典 lake effect

The main results are given as follows: Up to now,West Lake is eutrophic based on physical and chemical factors and zoobenthos after ecological treatment engineering; The ecological engeering has a little effect on zoobenthos community strcture, and most of zoobenthos belong to eutrophic species and mollusca species was absent,surprisedly, two exotic species Nephthys oligobranchia and Limnoperna sp.

研究中主要的成果为：不论是理化指标还是底栖动物指标显示，实施生态治理工程后西湖仍属于富营养化湖泊，西湖属于V类甚至劣V类水体。

To investigate the mechanisms of biohydrogen production by anerobic fermentation of solid organic waste, gas chromatography is used to analysis the biogas and volatile fatty acid in anaerobic bio-reactor. Firstly, the ability of hydrogen production by digested sludge from the West Lake, Enteobacter aerogences, digested sludge from sewage farm, the fluid of methane pool and dejecta have been studied. The rule of the ability of hydrogen production by different bacteria under different control condition. Simultaneity, the importance of the synergistic effect on hydrogen production has been proved.

本文首先选用西湖底的厌氧活性污泥、产气肠杆菌、污水处理厂的淤泥、沼气池发酵液以及猪粪等不同菌群对废弃食物——马铃薯进行厌氧发酵产氢特性实验研究，得到马铃薯在各不同菌群及工况下的发酵产氢能力，同时发现产氢菌间的协同作用很重要，在控制好发酵条件的情况下，产氢菌群发酵通常会好于单一产氢菌的发酵。

Using this varve dating results, we calibrate the other dating methods (radiocarbon dating and U-series dating) which were carried out in Lake Sugan. It was found that in the Little Ice Age with clastic varve type, radiocarbon dating has 2630 years radiocarbon reservoir effect, while beyond the LIA, the radiocarbon reservoir changed as the time passed.

通过已经得到验证的年纹层年龄-深度序列，对苏干湖其它测年手段~(14C测年和铀系测年进行验证，发现在碎屑类纹层沉积阶段即小冰期阶段，水生植物残体的~(14)C测年存在2630年碳库效应，小冰期以外时段碳库效应责随时间变化。

The effect of replacing the water in West lake is mostly rested on the area which can be replaced and the influx, whenas the size of the area is mostly related with field structure.

西湖水体的置换效果主要取决于可被置换区域的面积和引水量，而可被置换区域大小主要取决于流场结构。

In order to explore the feasibility of using native plant to evaluate and indicate water quality synthetically, we investigated the integrated evaluation and indication effect of Lemna paucicostata, an endemic species of Lemana in China to the water qualities of different sources（tap water, pond water pooled from rain rainwater uniquely, lake water received multiform sewage, and leachate）.

为探讨利用我国本土植物进行水质综合评价和指示的可行性，试验研究了我国特有的浮萍属植物——稀脉萍对不同来源水（自来水、雨水为唯一来源的池塘水、接纳多种排放废水的湖水及垃圾填埋场渗滤液）水质的综合评价和指示效果。

The effect of temperature on the population growth of Brachionus calyciflorus from the Nanhu Lake was studied at 15, 25 and 35℃ by population accumulative culture. The rotifer was fed with Scenedesmus obliquus at a concentration of 5.0×10^5 cells/mL.

应用群体累积培养法，以浓度为5.0×l0^5 cells/mL的斜生栅藻为食物，研究了温度（15、25和35℃）对南湖水体萼花臂尾轮虫种群增长的影响。

However, in this article, it is quite misleading that the way the author described Poyang Lake. This example, to some extent, is unproper and ulterior-motived so that the effect is remarkable.The figure 4000-50,everyone is shocked!

但在这篇文章中，对于鄱阳湖的不准确、错误的描述是具有误导性的，这个例子被不恰当的、别有用心的使用了，（并且其效果非常好，4000→50，非常震撼^_^）。

The premises of the simulation are that the runoff from upreach is 7.8× 108m3/a and the means of economization on water is in effect. When studied it was thought firstly the water for the lake area and the living plant of the oasis, then for forest-sod irrigation and farmland irrigation.

模拟计算是以上游下泄水量7.8×10~8m~3／a为前提条件，在实行节水措施，完善供水系统的情况下，首先满足维持和恢复一定规模湖泊面积，保证绿洲植被正常生长所需水量，然后考虑林草灌溉用水和农田灌溉用水量。

In the paper,the photosynthesis effect of plant under the water in the lake on DO and pH is discussed,and an algorithm for predicating this change in DO and pH is presented.
