您要查找的是不是：
- The SMTP service initiates communication when the routing topology changes, to inform the MTA that all messages must be rerouted. 当路由拓扑发生更改时,SMTP服务将启动通信,以便通知MTA所有邮件必须重新路由。
- List problems that each routing type encounters when dealing with topology changes, and describe techniques to reduce the number of these problems. 列举拓扑改变时每一种路由类型可能产生的冲突,描述减少冲突的技巧。
- When the network topology changes, switches and bridges recompute the spanning-tree and cause a disruption in network traffic. 当网路拓扑改变，交换器与桥接器会重新计算扩充树，此时会导致网路流量的中断。
- This new scheme can not only resolve the problem of multihop collisions very well but also be adaptable to topology changes. 经研究表明，该设计方案可以很好地解决自组织网络节点之间的通信冲突问题，同时能够较好的适应网络拓扑的迅速变化。
- Topology changes in one part of a network are not instantly known in other parts of the network due to propagation delay. 由于传播延迟，某部份的网路拓扑改变时，在网路的另一个部分并不见得能立即知道。
- The use of summarization to reduce the size of the routing table helps localize topology changes, a benefit that promotes network stability. 通过摘要的使用来减小路由表的尺寸有助于使拓扑变化局部化，好处是提升了网络的稳定性。
- For example, the routing engine calls the RoutingReset () function of the MTA if the routing topology changes to trigger message rerouting for all queued messages. 例如,如果路由拓扑发生更改,触发所有在队列中的邮件执行邮件重新路由,则路由引擎将调用MTA的RoutingReset()函数。
- As with the network discovery process, topology change updates proceed systematically from router to router. 如同网路发现程序一般，拓朴改变更新会从路由器到路由器有系统地进行。
- When the hold time expires, DUAL is informed of the topology change, and must recalculate the new topology. 当保持时间终止时，DUAL会被告知拓扑已经改变，并且必须再重计算新拓扑。
- For example, when using a routing protocol like Open Shortest Path First(OSPF), an upgrade or topology change on the internetwork causes a shortest path first(SPF) calculation. 例如，使用一个像开放最短路径优先（OSPF）这样的路由协议时，网络中的一个升级或拓扑改变会引起最短路径路径优先（SPF）计算。
- The model based on the implicit variational level set methods can handle topological changes automatically. 它基于隐式水平集变分方法，能够自动处理曲面拓扑结构的变化。
- The nobility usually resist social changes. 贵族通常反对社会变革。
- They want to see substantial changes. 他们想看到实质性的变化。
- This city underwent great changes. 这座城市经历了巨大的变化。
- The topology of the network may be ring, star or bus. 网络的拓扑结构可以是环形的、星形的或总线形的。
- She varied her dress as fashion changes. 她的衣着随着潮流而变化。
- He rings the changes on his old story. 他总是以不同的方式讲他的老故事。
- She undertook responsibility for the changes. 她承担了这些变革的责任。
