瓶颈

Nevertheless, Establishment of macro theory from micro property of material is also the so-called"bottle neck"in the linking study between mechanics and material science. All of these urge us to work on the theory of micromechanics carefully.

但是从材料的微观性质建立相应的宏观理论是力学和材料学这一交叉学科的"瓶颈"，这些促使我们更仔细地研究材料的细观力学理论。

Setting forth the realization method by hardware for searching minimal cutset of a graph with N-SearCut model. Then this method affords theory and practice fundament for solving this puzzle of searching for minimal cutset in reliability evaluation of power system.

By analyzing the characteristics of products and the production in mass customization,we discussed the modular group scheduling problem,and presented a heuristic method for minimizing the weighted tardiness.The method involved the identification of bottleneck operation,and the optimization of both of the production cost and the delivery performance.

基于对大规模定制生产模式的产品与生产特征的分析，描述了面向大规模定制的模块工件成组调度问题，提出了以识别瓶颈工序为基础的最小化加权拖期成组调度启发式方法，实现了生产成本与交货期的优化。

Association rules mining is a very active field in data mining and there are many algorithms today. In this field, the most classical algorithm is Apriori put forward by Agrawal et. al and it is used widely. The paper analyzes the advantages an disadvantages of Apriori, AprioriTid and AprioriHybrid algorithm in mining association rules. To solve the bottle of AprioriHybrid algorithm, a Support-Matrix method to rapidly verify the 2-frequent itemsets is put forward. To accelerate the speed of verify the k-frequent itemsets, a simple and highly efficient method of minimizing the trade database is given. All these two methods improve the efficiency of AprioriHybrid method.

关联规则挖掘是数据挖掘中一个非常活跃的领域，当前有许多种算法，最经典并被广泛使用的是Agrawal等人提出的Apriori算法及其衍生算法，本文分析了Apriori，AprioriTid和AprioriHybrid算法的优缺点，针对AprioriHybrid算法的瓶颈提出一种使用支持度矩阵对频繁2项集快速验证的方法，并给出一种简单易行，而又高效的逐步缩减交易数据库的方法，加快对候选频繁k项集的验证速度，从而提高了AprioriHybrid算法的效率。
