Due to the development of electronic computers, Analysis of the structure can be simplified plane over to a more precise calculation of three-dimensional space. For ultra-high frequency static set the structure, not only can greatly accelerate the speed, and may perform complex structure of the optimal design.

Since any frequent itemset is a subset of a maximal frequent itemset (an itemset is maximal frequent if it has no superset that is frequent), this paper proposes the DMFI (Discovery of Maximal Frequent Itemsets) algorithm for mining all the maximal frequent itemsets from data sets. This algorithm searches the maximal frequent itemsets in data sets from both bottom-up and top-down directions in the meantime. This paper proposes an algorithm that evaluates the boundaries on the support and confidence of uncalculated itemsets by exploiting the information provided by the calculated itemsets.
本文在经典关联规则的基础上,提出了一系列扩展的关联规则开采算法:发现关联规则的难度体现在发现频繁项目集上,事实上最大频繁项目集(其所有的超集都为非频繁项目集的频繁项目集)的集合已经包含了所有的频繁项目集,本文提出一种发现最大频繁项目集的算法DMFI(Discovery Maximal Frequent Itemsets),该算法采用自底向上和自顶向下相结合的搜索策略对数据空间进行有效的搜索。

Objective To examine the value of Edaravone in the treatment of vascular dementia through ethologic and pathologic changes induced by chronic cerebral ischemiaMethods Wistar rats were randomly divided into sham operated group,model group,edaravone group and duxil groupThe chronic cerebral hypoperfusion models were made by permanent bilateral occlusion of both common carotid arteriesThe memory ability and ultramicrostructure of brain tissue were observedResults The escape latencies in model group were more significantly prolonged than that in the other groups (P<005)But there was no significant difference between edaravone and duxil groupAnd pathologic changes observed by electron microscope in nerve cell of edaravone group and duxil group and model group were fairly light than that in sham operated groupEdaravone group had increased mitochondrium and frontal membranous synaptic vesicle and more productive metabolic activityConclusions Edaravone can lessen injures of hippocampal neurons loss to improve the spatial learning and memory abilitiesAnd it is proved further that edaravone can treat VD
目的 观察依达拉奉对慢性缺血致血管性痴呆大鼠行为学及形态学的影响,探讨依达拉奉在治疗VD中的应用价值。方法实验分假手术组、模型组及都可喜对照组及依达拉奉治疗组,应用双侧颈总动脉结扎方法制备慢性脑缺血大鼠痴呆模型,观察各组大鼠的记忆功能及脑组织超微结构改变。结果缺血组水迷宫表现同对照组、都可喜组及依达拉奉组相比有显著差异(P<005),依达拉奉组与都可喜组相比未见显著差异。同时电镜观察结果也发现依达拉奉组及都可喜组与模型组及假手术组相比神经细胞病理改变较轻,且依达拉奉组线粒体及前膜突触小泡增多,代谢活动较都可喜组旺盛。结论依达拉奉可能通过减轻海马神经元的损伤来改善慢性脑缺血大鼠空间学习记忆障碍,证明依达拉奉对慢性缺血致VD大鼠具有治疗作用。

Although many scholars had attempted to define it, the typical definitions of niche are Grinnell's space niche, Elton's functional niche and Hutchinson's hypervolume niche; Niche metrics include niche breadth, niche overlapping, niche volume and niche dimension, among which niche breadth and niche overlapping are two important indexes that can be used to characterize a species niche and the relationships between species niches.
许多学者都试图给生态位下定义,但最具代表性的当推Grinnell、Elton和Hutchinson分别给出的&空间生态位&、&功能生态位&和&多维超体积生态位&定义;生态位测度包括生态位宽度、生态位重叠、生态位体积及生态位维数等,其中生态位宽度和生态位重叠是描述一个物种的生态位以及物种生态位间关系的重要指标。
