做到这一点真的没有任何损失，而且 SSH 甚至（可选地）添加其自己的压缩层来增强性能。

There is really no loss in doing this, and SSH even (optionally) adds its own compression layer to enhance performance.

该压缩算法在不损失数据的前提下，实现了对海量数据的快速，高压缩比压缩。

The algorithm realizes the compression for large number of data in high speed and high compression ratio in undamaged way.
