Additionally, the properties and normal extension construction of normal Boolean function is studied, and checking algorithm of normal is discussed.

另外，本文分析了正规布尔函数的性质和正规扩展的构造方法，讨论了布尔函数正规性的检验算法，这对于Bent函数的分类问题的解决具有重要意义。

This passage analyzes the advantage and disadvantage of the Boolean Model and the Vector Space Model in information retrieval model: the Boolean Model is simple to realize, but its classification ability is limited and the logic expression formula is strict.

本文分析了信息检索中传统文档特征表示的布尔逻辑模型和向量空间模型的优缺点：布尔逻辑模型虽机制简单、容易实现，但是它的分类能力有限且逻辑表达式过于严格；向量空间模型将文档映射到连续域向量空间，为进一步的权重计算等多元处理提供了基础，但容易忽略文档集合中各个文档的一些共有特征。

The chapter explores Boorstin\'s pragmatistic characters from different dimensions such as theory and practice, experimentalistic exploration, pragmatistic value, etc. The author wants to claim that Boorstin\'s pragmatism is a value deeply rooted in the America\'s specific soil of history and culture.

该章从理论和实践的关系、"实验性"的探究以及实用主义价值观等维度考察了布尔斯廷实用主义哲学的主张和特点，同时，笔者还试图说明，布尔斯廷的实用主义哲学是根植在美国特定的历史、文化土壤中的一种价值观。

由于n个元素的有限集有且只有个子集由于个元素的有限集有且只有2n个子集，而且很显然有限布个元素的有限集有且只有个子集，尔代数一定是有限集合代数，所以对某个整数n而言而言，尔代数一定是有限集合代数，所以对某个整数而言，每个有限布尔代数也有且只有2n个元素。例如，上文定义的集合T的限布尔代数也有且只有个元素。

For example, the set algebra for the set T defined above corresponds to a Boolean algebra of 32 elements.

例如，上文定义的集合的个元素集合代数就对应一个有32个元素的布尔代数个元素的布尔代数。

Language righteousness checked without any error, we can get table name and the corresponding fields names. The paper adopts the stack to realize calculating the logic expressions type. Through the value of the logic expressions, we can check whether conditions in the QL establish or not.

语义检查无误后，经分析可以得到表名和相应的列名，用栈来实现布尔表达式的求值等，布尔表达式的计算结果，用以检查条件是否成立，为事务处理提供函数接口，以便进行正确的查询。

Language righteousness checked without any error, we can get table name and the corresponding fields names. The paper adopts the stack to realize calculating the logic expressions type. Through the value of the logic expressions, we can check whether conditions in the QL establish or not. And we pass the result to the tranction disposal layer which can deal with the right search.
