However, an efficient and effective production test technique is the final hurdle of the massapplication of the asynchronous circuits.
然而，高效的产品测试技术依然是异步时序电路大规模应用的一个很大的障碍。

Data mining is a technique that abstracts the helpful information and knowledge from the massapplication dataset by relevant rules and policies.
数据挖掘是依据相应的规则和策略，从海量的实际应用数据中提取有用信息和知识的一种技术。

However, using the massapplication database, some problems emerge, for example, how to identify the data effectiveness, how to make a useful conclusion and how to tell people the data efficiently.
