The contributions are listed as follows:(1) a single-pass closed frequent itemsets mining process based on reverse lexicographic order FP-tree is introduced for mining classification association rules, which uses a kind of mixed item-ordering searching policy to satisfy the single-pass requirement of data streams and uses the bitmap technology to improve the efficiency;(2) the concept of self-support for filtering rules is proposed to improve the precision.

主要贡献在于：1提出了一种基于逆文法顺序FP-Tree的频繁闭项集单遍挖掘过程，用于挖掘类关联规则，该过程采用了一种混合项顺序搜索策略以满足数据流挖掘的单遍性需求，并采用位图技术提高效率：2提出了"自支持度"概念，用于筛选规则以提高算法分类精度。

In the first part of this paper, we propose New-Moment to mine closed frequent itemsets. New-Moment uses bit-vectors and a compact lexicographical tree to improve the performance of Moment algorithm.

我们在此篇论文的第一部份提出 New-Moment 演算法在资料串流环境中探勘封闭式频繁项目集，New-Moment 使用位元向量以及精简的 closed enumeration tree 大幅改进原来 Moment 演算法的效能。

Based on lots of statistics, starting from China's textile and clothing export status quo, this paper expounds and analyzes the cause of formation of foreign major problems facing China's textile and clothing export—the limits of special clauses, regional integration of international trade, technical barrier, frequent anti-dumping. Besides, analysis has also been given on technical backwardness, unreasonable product structure, over concentration of export market, reduction of international competitiveness and large quantity but low price.
