某工作站采用时钟频率f为15MHz，处理速率为10MIP/S的处理机来执行一个已知混合程序。假定每次存储器存取为1周期延迟，此计算机的有效CPI是(2)，假定将处理机的时钟频率f提高到30MHz，但存储器子系统速率不变。这样，每次存储器存取需要两个时钟周期，如果30%指令每条只需要一次存储存取，而另外5%每条需要两次存储存取，还假定已知混合程序的指令数不变，并与原工作站兼容，则改进后的处理机性能(3)。

, the data mining techniques are introduced broadly including its producing background, its application and its classification. The principal techniques used in the data mining are surveyed also, which include rule induction, decision(67), artificial(68)network, genetic algorithm, fuzzy technique, rough set and visualization technique. Association rule mining, classification rule mining, outlier mining and clustering method are discussed in detail. The research achievements in association rule, the shortcomings of association rule measure standards and its(69), the evaluation methods of classification rules are presented. Existing outlier mining approaches are introduced which include outlier mining approach based on statistics, distance-based outlier mining approach, data detection method for deviation, rule-based outlier mining approach and multi-strategy method. Finally, the applications of data mining to science research, financial investment, market, insurance, manufacturing industry and communication network management are introduced. The application(70)of data mining are described.
