湖底的

The reduction of species richness was the most remarkedble in Trichoptera and Mollusca. Species succession of macrozoobenthos was closely related to the changes in environmental conditions such as the isolation of the lake from the river, eutrophication, and disappearance of macrophytes. Perhaps, the latter two changes were more important.

分析表明东湖底栖动物群落的演替与湖泊环境条件的变化关系密切，这些变化主要包括：江河阻隔，湖泊富营养化的加剧以及水生高等植物的消失，其中后两个因素相对前一个显得更为重要。

志，"中国一颗十四世纪的荷花种子已经重新获得生命力来自远古的湖底，适当的这古老的种子发芽在报告上"。

The researches show that fan delta, alluvial plain, delta, lacus and sublacustrine fan develop, each sedimentary facies are divided into several subfacis again. The probability cumulative grain size curves incude "uphill arched arc" pattern, one segment pattern, bi-segment pattern, tri-segments pattern, multi-segments pattern, complicated bi-segment pattern, complicated tri-segments pattern,"low slope multi-segments" pattern,"high slope multi-bouncing population-one suspension population" pattern,"high slope multi-bouncing population-one suspension population-transitional zone" pattern,"high slope and multi-bouncing population" pattern,"broadly uphill arched arc" pattern and so on, each subfacis has own peculiar probability cumulative grain size curves.

研究表明，该地区发育的沉积相有扇三角洲、冲积平原、三角洲、湖泊、湖底扇，每一种沉积相又分为几种沉积亚相类型；该地区碎屑岩的粒度概率累积曲线特征主要包括：&上拱弧形&式、一段式、两段式、三段式、多段式、复杂两段式和复杂三段式、&低斜多段&式、&高斜多跳一悬&式和&高斜多跳一悬夹过渡&式、&高斜多跳&式、&宽缓上拱&式等，每种沉积亚相类型对应其独特的粒度概率累积曲线特征。

And as the Lake Michigan floor north of Green Bay rises, all that water sloshes south towards Chicago.

格林湾北面的密西根湖湖底上升，所有的水都会流向南面的芝加哥。

And as the Lake Michigan floor north of Green Bay ris es , all that water sloshes south towards Chicago .

并且当格林湾北部密歇根湖的湖底上升的时候，所有的水都朝南向着芝加哥的方向流。

For example, in some parts of the lake, blue-colored species tend to live in the shallows, and red ones near the bottom.

例如，在维多利亚湖的某些地方，蓝色的鱼稀饭生活在浅水处，而红色的鱼往往生活在湖底。

At last, we studied the function of benthic algae in ecosystem of eutrophic lake, the primary productivity of benthic algae and the role of periphyton in phosphorus retention were investigated in a littoral zone of shallow lake.

最后对底栖藻类在富营养化湖泊生态系统中的作用和功能进行了初步研究，测定了不同季节东湖底栖藻类的初级生产力和对水体中磷的滞留作用。

而且，种子的生命力很强，根据美国植物学杂志，&中国一颗十四世纪的荷花种子已经重新获得生命力来自远古的湖底，这古老的种子发芽已经在报告上发表&。

In the shallows, the dark, water-soaked sticks and twigs, smooth and old, were undulating in clusters on the bottom against the clean ribbed sand, and the track of the mussel was plain.

浅水处，黑魆魆的树干和枝梢堆积在湖底透明的沙石上，浸在水里，纹丝不动。蛤贝爬过的轨迹清晰可见。

Could it be that beneath the surface of Lake Titicaca, there lies the lost city of Atlantis?

有可能在的的喀喀湖底埋藏着失落的亚特兰蒂斯吗？

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
