The new algorithm constructs an association graph to represent the frequent relationship between items, and recursively generates frequent closed itemsets based on that graph.

GRG算法构造关联图代表频繁项之间的频繁关系，并递归地从关联图中产生频繁闭项集。

I confess to an occasional—nay, frequent—craving for coffee and to an occasional—nay, frequent—craving for thrills, but, as for happiness, I should prefer to grow broad beans and lettuces in a walled garden and to sit in a deck-chair in my shirtsleeves, watching their brief lives till they were ready for the table.

我不否认自己偶尔渴望——不，是经常渴望——咖啡，也偶尔渴望——不，是经常渴望——刺激，但说到幸福，我宁可在有围墙的园子里种下蚕豆和莴苣，身上只穿件衬衫，坐在帆布躺椅上，观察它们短暂的生命，直到它们成为盘中菜。

I confess to an occasional----may, frequent----craving for coffee and to an occasional----may, frequent----craving for thrills, but, as fro happiness, I should prefer to grow broad beans and lettuces in a walled garden and to sit in a deck-chair in my shirtsleeves, watching their brief lives till they were ready for the table.

我承认我偶尔渴望----不，是经常渴望----咖啡，也偶尔渴望----不，是经常渴望----刺激，但说到快乐，我宁可在有围墙的园子里种蚕虫和莴苣，我不穿外衣，坐在帆布睡椅上，观察它们的短暂生命，直到它们成为盘中菜。

Then, considering the knowledge represented by a set of frequent patterns, we investigate the problems of preserving sensitive patterns in data sharing, hiding sensitive patterns in frequent pattern sharing, and also blocking inference channels in frequent pattern sharing. The main contributions are as follows:(1) For the problem of preserving anonymity in data sharing, we propose a clustering-based approach for implementing l-diversity.

本文首先研究了数据共享中匿名保护问题，接着以频繁模式为知识的表现形式，研究了数据共享中的敏感模式保护，频繁模式共享中的敏感模式隐藏，以及频繁模式共享中的推理控制等问题，主要的研究成果如下：(1)针对数据共享中的匿名保护问题，提出了一种基于聚类的l-多样化实现方法。

The set of frequent closed patterns determines exactly the complete set of all frequent patterns and is usually much smaller than the laster. Yet mining frequent closed patterns remains to be a memory and time consuming task.

频繁闭合模式集惟一确定频繁模式完全集并且尺寸小得多，然而挖掘频繁闭合模式仍然是时间与存储开销很大的任务。

So, this paper, based on mathematical expectation, brought up the concept of the positively correlated frequent itemsets, and improved the algorithm of mining frequent itemsets directly in FP-tree to mine positively correlated frequent itemsets. In this way, a solution to the above mentioned problems was got.

针对以上问题，基于数学期望，提出了正相关的频繁项集的概念，并改进了一种直接在FP-树中挖掘频繁项集的算法，挖掘出正相关的频繁项集，从而有效地解决以上问题。

An efficient algorithm based on FP-tree and support array for mining maximal frequent itemsets is proposed. At first the FP-tree and the support array are created at the same time. Then a maximal frequent itemsets tree MAXFP-tree is built up to store all the maximal frequent itemsets. Therefore, it can reduce the search space and improve the efficiency of the algorithm.

提出了一个基于频繁模式树即FP-tree和支持度数组相结合的最大频繁项集挖掘算法，首先建立FP-tree，同时建立支持度数组，然后在此基础上建立最大频繁项集树MAXFP-tree，MAXFP-tree中包含了所有最大频繁项集，缩小了搜索空间，提高了算法的效率。

The multiple linear regression analysis suggested stronger associations for shoulder pain and "frequent bending while moving/lifting heavy objects" or "frequent long-lasting moving/lifting objects"; finger/wrist pain and "continual twisting of the wrist" or "frequently vigoro us action of the wrist"; and low back/waist pain and "frequent bending while moving/lifting heavy objects."

多变量回归分析所显示较强的相关性包括：肩部疼痛与「需经常弯腰从地面抬取重物」或「持续搬抬重物达一分钟以上」等动作；手指手腕疼痛与「手腕持续旋转搓绕」或「手腕经常出力弯曲」等动作；以及下背腰部疼痛与「需经常弯腰从地面抬取重物」。
