Implement mdbsm in the practical project , and a lot of tests and analyses has been done to guarantee its effectivity and efficiency . by a large range test of experiments , the mdbsm model proved to be work fine and fit for real requirement 通过大量实验数据分析证明, mdbsm模型在完成时间和数据同步响应方面表现出良好的时间优势,较好的满足了一般移动设备和pc服务器之间的异构数据库数据同步需求,达到了预期的目标,并且该模型具有一定通用性和可移植性。
Corresponding program is designed based on the theory , and a numerical computation about a sphere near wall is utilized to verify the effectivity of the program . then satisfactory results are obtained when underwater vehicle g oes toward s ubmarine a long the fixed p aths by numerical computation , and corresponding analysis follows 在此基础上，编制了相应的计算程序，并以球体在壁面附近时的运动进行了验证，然后，根据水下机器人靠近潜艇的方案，进行了数值计算，给出了较为满意的结果，并针对各种情况作了相应的分析。
This system involves many resources , such as manpower , material resources , financial resources , time , vacuum , and information , it also involves some system action , such as plan , organize , lead , and control . so only the system approach can manage these segments , and the school must use the system management of corporation for reference to enhance the effectivity of the management of school - based curriculum development 在这个系统中，涉及人力、物力、财力、时间、空间和信息等资源，涉及到系统的计划、组织、领导和控制等行为，需要运用系统的管理方法进行管理，学校也有必要借鉴工商企业中的系统管理方法来增进校本课程开发组织管理的有效性。
Mining of frequent closed itemsets greatly improve the rules mining effiency and effectivity of the resulting rules , hence release the users of the burden . we implement the frequent closeu itemsets mining algorithm fcis and the frequent closed itemsets rules mining algorithm ci _ rules . experiments diplay that compared with the latest published algorithm - the closet algorithm proposed by jiawei han , our algorithm is more than two malgtitudes faster and has fabulous scalability ; ci _ rules algorithm overtakes fpmine - spf algorithm by more than two malgtitudes and has extraordinary scalablity 实验表明，在相同数据集上，与已发表的最新成果? han的closet算法相比，本文算法fcis速度提高两个数量级以上，并有极好的可伸缩性； ci _ rules算法挖掘频繁闭项集规则的运行速度较fpmine - spf算法挖掘关联规则的速度快两个数量级以上，并有非凡的可伸缩性。
At the same time , the observers of nonlinear system with and without uncertainty have been analyzed and designed based on the input - output linearization theory . the training rule for the weights of the rbf nns has been proposed in the paper based on the known system model and given lyapunov function . the simulation shows effectivity of the designed observer 在设计含有建模不确定性的系统的观测器时，用rbf神经网络对不确定性进行建模，在给定lyapunov函数的基础上设计了神经网络加权系数的调整规律并将非线性观测器应用于神经网络实现的动态逆控制系统，设计了仿真对其有效性进行了比较验证。
In this thesis , flow regime identification and malfunction diagnosis of fluidization were studied with fractal technology , the presented methods for both flow regime identification and malfunction diagnosis were proved of effectivity . main achievements are as following : 1 . fractal brownian motion ( fbm ) was made from gauss noise and compared with pressure fluctuation signal of gas - solid fluidization , which demonstrated the similarity between the fbm and the signal 在通过fbm (分数布朗运动)数据仿真证明了气固流化床压力波动信号与分数布朗运动是相似的基础上，提出了用分数布朗运动来模拟气固流化床压力波动信号，并采用r s分析法从信号时间序列中提取出hurst指数，通过分析信号hurst指数值对流化床流型和结块故障进行了研究。
The main work of the paper is summarized as followings : the algorithm is improved somewhat , the algorithm is implemented in pc by mathematica software and the effectivity is proved to by testing all the examples that have been proved by d . zeilberg and h . wilf using wz - pair method and testing many identities of the book named " combinatorial identities " , which was written by h . w . gould in 1972 本文的主要结果为：对算法作了一定的改进；在微机上，用数学软件mathematica实现了这种算法；试算了d . zeilberg和h . wilf用wz对方法算过的所有例题，对h . w . gould的一本名为“ combinatorialidentities ”的书中大量恒等式也作了验证。
