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。

How to get the optimal set of coins and how to accomplish payment with the set are the keys to solve the divisibility problem.

Of course, you also can have a try the method that uses from above to below, search the market total scale that sees your product to have to the net first how old, your set target, with year be an unit and need not be a month, with take division, advanced even algebra, target of the first year is occupational the market share of 15%, set breaks up every year one time (it is easy to such comparison, excel is pulled came out), the 2nd year 30%, the 3rd year 45%, the 4th year 60%......

当然，你也可以试试看用自上而下的方法，先到网上搜索一下看你产品的市场总规模有多大，你设定目标，以年为单位而不必是月，用乘除法，甚至高等代数，第一年的目标是占领15%的市场份额，设定每年翻一番(这样比较容易，Excel一拉就出来了)，第二年30%，第三年45%，第四年60%。。。。。。

Through in the practice feeling about divulgement, vibration and synthesis operational performance of the pump and life of the key components and the pedestal and intact operating horary inside contact in whole set, try to look for one kind of reasonable and economical corrosion resisting stainless steel material of the pedestal and pump body,in the hope prolonging ZA200-315A and HC200-250A type stainless steels acid resisting pump whole set operation life.

通过实践摸索泵的泄漏、振动及泵综合使用性能和关键部件的寿命、底座寿命与整机完好运行时间的内在联系，试图寻找一种合理经济的耐腐蚀不锈钢底座及泵身材质，以期延长ZA200—315A型及HC200—250A型不锈钢耐酸泵的整机运行寿命。

The perfect solution, and You do not have the heart to uninstall the other tools are also set according to such a similar way, they set to not automatically update on it.

就完美解决了，其他你不忍心卸载的工具也都按照这样的类似的设置方式，把他们设置成不自动升级就可以了。

Aiming at the currently shortage of XML streams quality detecting, this paper proposes a new forecasting method of XML streams quality by least squares support vector machines, which is used the method of XML keys' vector matrix as windows, and vector product wavelet transform to multilevel decompose and refactor the XML streams series, that can fulfill real-time checking demand of XML quality, and ensure constraint, consist- ency and integrality. For even more adapting net load, it proposes a control strategy by weight and adaptive adjustment to ensure XML streams quality.

针对当前XML数据流质量检测存在的不足，提出构建XML键的矢量矩阵作为窗口，利用矢量积小波变换多级分解与重构XML数据流，再结合最小二乘支持向量机对XML数据流质量进行预测的一种方法，满足XML数据流质量重构时实时检测的要求，保证XML数据的约束性、一致性与完整性；为了更好的适应网络负载，采取加权与自适应窗口调整等调度策略充分保证XML数据流的质量检测。
