某市准备新建一座污水处理厂，集中处理A、B、C、D四家工厂的工业污水．一个化学兴趣小组的同学了解到这四家工厂排出污水的主要成分分别是K₂C0₃、CuS0₄、NaOH、HCl中的一种物质，他们根据工厂布局．设计了一套沟渠模型进行模拟实验．如图所示是他们的实验观察记录（“一“表示水流方向）．据图回答：

（1）写出A、B厂污水主要成分的化学式：A______B______

（2）写出产生蓝色浑浊的化学方程式：______．

Border Gateway Protocol (BGP) is inter-autonomous system (71) protocol. BGP is based on a routing method called path vector routing. Distance vector routing is not a good candidate for inter-autonomous system routing because there are occasions on which the route with the smallest (72) count is not the preferred route. For example, we may not want a packet through an autonomous system that is not secure even though it is the shortest route. Also, distance vector routing is unstable due to the fact that the routers announce only the number of hop counts to the destination without actually defining the path that leads to that (73) . A router that receives a distance vector advertisement packet may be fooled if the shortest path is actually calculated through the receiving router itself. Link (74) routing is also not a good candidate for inter-autonomous system routing because an internet is usually too big for this routing methoD. To use link state routing for the whole internet would require each router to have a huge link state database. It would also take a long time for each router to calculate its routing (75) using the Dijkstra algorism.

（74）是（）

A.status

B.search

C.state

D.research
