This is also made possible by the use of three failure groups, which are further explained under Data replication.
这是通过使用三个故障组得以实现的，我们将在数据复制一节详细对之进行介绍。
Setting up of a different replication topology under a base that already has replication set up can be quite tedious.
在已经设置了复制的条目基下面设置不同的复制拓扑很麻烦。
A forwarding layer maps ranges of source IDs to physical databases, and replication is handled by building a tree of such tables under the same forwarding address.
该层将一段源id映射到物理数据库，对于同一个物理地址的表，通过建立树来处理。
This is especially crucial under failover conditions when WebSphere USES the application session ID in the encoded URI to route requests to the replication peers of the failed application servers.
这在故障转移情况下尤其重要：WebSphere使用已编码uri中的应用程序会话id将请求路由到已失败的应用程序服务器的副本服务器。
Finally, the mapping of the placement group to object storage devices is a pseudo-random mapping using an algorithm called Controlled Replication Under Scalable Hashing (CRUSH).
最后，放置组到对象存储设备的映射是一个伪随机映射，使用一个叫做ControlledReplication UnderScalable Hashing (CRUSH)的算法。
During the replication and transcription, DNA unwinds the double helix under the control of an enzyme. It is a very complex process beyond a physical description.
DNA双螺旋链在复制和转录的过程中要在酶的催化下解旋，这是一个高度复杂的过程，目前还无法用物理学的方法来描述。
