针对频繁闭项集挖掘算法中数据结构与处理机制复杂的问题，提出窗口快速滑动的数据流频繁闭项集挖掘算法——MFWSR。

This paper proposes an algorithm of Mining Frequent closed itemsets with Window Sliding Rapidly(MFWSR) against the complexity of data structure and process for determination.

闭包还有一项重大的优势：让实施策略变得容易。

Closures have another huge advantage: they make it easy to enforce policy.

例如，若要处理一项事务，采用闭包后，您就能确保事务代码总能由适当的函数调用界定。

For example, if you have a transaction, you can make sure that your code always brackets transactional code with the appropriate function calls.
