In this paper a genetic algorithm four-dimension data assimilation system was applied to the more complex MM5 model, we verify the performance of the genetic algorithm assimilation system, we take the a heavy rainfall process during 04-05, July, 2003 as the experimental research object, and carry out data assimilation experiment of actual observation data, compare the experimental results of the genetic algorithm assimilation system and MM5 adjoint model assimilation system with the experimental results without assimilation, the following is the result:genetic algorithm assimilation system is used not only in a barotropic primitive equation but also in the complex model, MM5, for example, in the ideal experiment the result of the genetic algorithm assimilation system is better than the MM5 adjoint model assimilation system, in the assimilation experiment of actual observation data, whichever assimilation system is used, the initial field of numerical prediction model is effectively improved and the prediction effect of physical field and rainfall are somewhat enhanced.

Theexpected utility theory based on the axioms isalso very important in modern decision-making theory.Form late fifties lastcentury,some scientists ahead by Allais and Edwards,try to check the facticity ofthe rational decision-making models applied to the real decision-making behavior,but find it unsatisfactory.For example,Allais Paradox and Preference Circleschallenge the axioms critically.
从二十世纪五十年代后期开始,以Allais和Edwards为首的一批学者从心理学的角度参与了实际决策行为的研究,他们从实证的观点去考察理性决策模型在实际决策行为中的真实性,不断地发现这些模型在应用中表现出各种偏差,Allais悖论的设计和克星循环现象的发现对Von Neumann-Morgenstern理性行为公理提出了有力的挑战。

These can offer students so advantage opportunities that is good for selecting job, powerful major feelings and excellent professional dedication. Finally, we need emphasize several main points. The main point is to hold profession ethics affects differences between school and enterprise, including guiding principle"s difference, varies between content and thought, varies between evaluation and standard. According to student'majors, collectedly leading related the corporate culture to increase schools'professional ethics educations effects. On the base of analyzing school"s education, to find a kind of educational means of school, to persist obverse education and obverse guiding, to strengthen students'faith education. According to the students thoughts fact, we should avoid faith educations dogmatism and emptiness and improve our clear aim and effect for serving people.
最后要突出几个重点:把握学校与企业职业道德教育不同点,包括指导思想上的不同、内容和方法上的不同以及评价方法和标准的不同等,根据学生的专业要有选择地引入相关的企业文化,增强学校职业道德教育的实效性;结合具体实际,加强对学生的诚信教育,在客观分析学校教育对象诚信状况的基础上,找到具有校本特色的诚信教育方法,坚持正面教育与正面引导为主,并加强学生诚信实践教育,避免学校诚信教育的教条化和空洞化;针对学生的思想实际,提高为人民服务思想教育的针对性和有效性。

The method is realized via the following steps: first to apply Isomap or LLE to get the embeddings of the original data set in the low dimensional space; then to obtain support vectors, which are the most significant and intrinsic data for the final classification result, by using support vector machine on these low dimensional embedding data; subsequently to get support vectors in the original high dimensional space based on the corresponding labels of the obtained low dimensional support vectors; finally to apply support vector machine again on these high dimensional support vectors to gain the final classification discriminant function.
数据挖掘是数据库知识发现中最重要的步骤之一,其目标是从获取的数据中高效准确地挖掘出我们所需要的信息。在实际应用中,数据往往呈现海量、高维、非线性等特性,这些特性给数据挖掘带来了很多问题,例如海量特性导致的计算效率低下问题、高维特性带来的维数灾难问题和非线性特性引起的线性模型失效问题等。幸运的是,实际中高维数据的属性之间往往存在一定的规律性和相关性,即实际数据经常存在着外在与内在两个维数。
