在DB 2 9.7中，行压缩(也称为深度压缩)通过把跨行重复出现的值模式替换为更短的符号字符串来压缩数据行。
In DB2 9.7, row compression, also referred to as deep compression, compresses data rows by replacing patterns of values that repeat across rows with shorter symbol strings.
数据中的模式：对于特定的表空间或分区，数据中重复出现的模式的出现频率将决定压缩的效果。
Patterns in the data: the frequency of recurring patterns in the data determines how effective compression will be for a particular table space or partition.
该分组操作本地化重复，从而提高压缩程度。

由于它的扫描范围比其他压缩技术更大，它可以找到并压缩更多的重复模式，因此实现的压缩率非常高(见图1)。
By scanning a larger area than other compression techniques, it can find and compress more repeating patterns, and thus achieve very high compression ratios (see Figure 1).
正如上面所讨论的，对大文件进行文件级别的压缩可能不太实际；但正如预期的那样，文件级别的压缩会取得更好的结果，因为它是在整个文件中寻找重复的字符串。
As discussed above, file-level compression of large files might be impractical; but as expected, file-level compression achieves better results since it looks for repeated strings in the whole file.
当处理图形文件(例如jpeg图像)时，压缩就不那么好用了，因为数据更加难于减少重复。
When working with a graphic file, such as a JPEG image, the compression doesn't work as well because the data is more difficult to de-duplicate.
其他压缩技术只在每行的一部分中寻找重复模式，而StorageOptimization会扫描整个行，无论行中有多少列。
Unlike other compression techniques that scan only a portion of each row for repeating patterns, Storage Optimization scans the entire row, regardless of how many columns it intersects.
有大量重复字符串的数据有巨大的压缩潜力。
Data with a high number of repeating strings can result in significant compression.
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.
三个StorageOptimization组件中最重要的是压缩，它分析数据库中的每一行，寻找重复出现的数据模式。
The first of the three Storage Optimization components is compression, which examines each row in the database for recurring patterns of data.
然后，在下一次空闲时间压缩时，计算机可以重复此过程。
Then, at the next idle time compression, the computer can repeat the process.
清单4包含了一个简单的脚本，它使用sed和awk将ausearch的输出压缩成只有不重复的(忽略时间)可执行程序和端口号字段。
Listing 4 contains a simple script using sed and awk to compress the output of ausearch down to only the non-duplicated (time omitted) executable and port number fields.
我们可以重复这一过程中，我们的爆炸造成更频繁的压缩机旋转速度越来越快，充电燃烧室更加迅速。
We can repeat this process, creating our explosions more frequently as the compressor spins faster and faster, recharging the combustion chamber ever more quickly.

这种强调心理、情绪的叙事时间模式呈现出叙事时序的错位、时长的被压缩和重复等。
The stagger narrative time order, the compressed time length and repeating narration are the main aspects of the mental time mode.
本文提出了将磁脉冲压缩开关结合LC反转倍压电路应用于高重复率紧凑型准分子激光器的技术。
In this paper a magnetic pulse compressor (MPC) combined with LC inversion circuit applied in compact excimer laser has been put forward.
这也有助于使图像有几个颜色，因为这样的预测误差会重复(和zlib压缩，好)。
It also helps that the image has few colors, because then the prediction errors will repeat (and Zlib will compress that nicely).
制冷工质在蒸发器内吸取热量，温度升高变成过热蒸气，进入压缩机重复循环过程。
Working in the evaporator refrigeration in heat, temperature from overheating steam into the compressor, become repeat process.
随后，蒸气又流过压缩机，重复上述循环。
The vapour then passes to the compressor and the cycle is repeated.
压缩取出发生多次的相同事件，检查重复的信息，去除冗余，按单一的事件报告。
Compression takes multiple occurrences of the same event, examines them for duplicate information, removes redundancies and reports them as a single event.
