1·Patterns of deltas are ephemeral .

三角洲式样的变化是很快的。

2·'Currently visible deltas on delta tree' selected.

选中' delta树中当前可见的delta ' '。

3·The new version is then stored as the deltas between the two.

然后，以两者之间的增量的形式存储新版本。

4·Wrapper table functions that report deltas relative to the baseline data.

报告相对于基线数据的差值的包装器表函数。

5·Deltas and diffs serve two distinct purposes, both of which are important.

增量和差别为两种不同的目的服务，它们都很重要。

6·The size and location of the deltas were controlled by distributary watercourses.

分流河道发育情况控制了三角洲朵体的大小和位置。

7·Most version control systems cannot store binary files as deltas, but Subversion can.

大多数版本控制系统不能将二进制文件存储为增量，但Subversion却可以。

8·Note: Only performance metrics that are of type snapshot counter have deltas calculated.

注意：只有快照计数器（snapshot counter） 类型的性能指标才能计算差值。

9·The saved differential data is known as a delta, or, more loosely, as the file's deltas.

这里保存的差异数据被称作增量（delta），或者文件的增量。

10·The valleys were the source of sediment that was carried downstream and dumped into the deltas.

河流峡谷将会是沉积物的重要来源，这些沉积物是被河水携带着，顺流而下汇集到三角洲的。

三角洲

1·China has 61 million acres of wetlands, which include swamps, mangroves, lagoons, river deltas, lakes, and coastal areas that collectively cover about 2.5 percent of the country.

中国湿地面积大约61英亩，包括沼泽、红树林、环礁湖、河流三角洲、湖泊以及沿海一些地区，总计为国土面积的2.5%。

2·As the oceans swell with water from melting ice sheets, it is the crowded river deltas in southern Asia and Egypt, along with small island nations, that are most at risk.

由于冰片融化，海洋水位增加，位于南亚和埃及的人口密集的河流三角洲以及一些小岛国，面临的危险最大。

3·The valleys were the source of sediment that was carried downstream and dumped into the deltas.

河流峡谷将会是沉积物的重要来源，这些沉积物是被河水携带着，顺流而下汇集到三角洲的。

4·The result is a collection of 40 images of deserts, deltas, glaciers, cloud formations, mountains, valleys and coastlines where light is the medium and not paint.

这种最终的图片中包括了四十组沙漠、三角洲、冰川、云层、高山、峡谷及海岸线的图像，其中光是自然呈现的，并非特意的涂色。

5·Hoping to catch a glimpse of the Deltas, I went to the kitchen door, a glass door, and cupped my hands beside my eyes to take a look.

满怀希望可以看上一眼“三角洲”，我走向厨房的玻璃门，双手窝在两眼边，向外看了一看。
