时间压缩比水平、垂直位置的组合算法更重要，因为它可以实现附近某个位置的压缩比例为10：1。

Time compression is more significant than horizontal and vertical algorithms combined, as it can achieve compression somewhere in the neighbourhood of a 10:1 ratio.

在主存储上使用重复数据删除也会有成效，但却不要期望可以达到像备份实施时典型的2.5倍到3倍的比例这样高的数据压缩比。

There are some gains to be had here, but don't expect the same data reduction ratios that you'll see in backup operations; 2.5X to 3X is typical.

请注意，压缩比上述反映膨胀率，这是燃烧室的量的比例时，活塞的下死顶死中心，中心会显示。

Note that the compression ratios shown above reflect the expansion ratio, which is the ratio of the combustion chamber volumes when the piston is at Bottom dead centre and Top dead centre.
