Where a lot of other machines might have ports and protrusions along their edges, the Air has none -- it swoops inward from the edge to the base with only two spots for plugs, a new, 90-degree angled MagSafe power connector on the left underside, and a clicky, extremely sturdy-feeling foldable door that is impossible to open while resting on the table, and basically requires picking the entire machine up.

尽管大部分的手提电脑在两侧都会有接口和插槽(原文为protrusions，意为隆起的部分，此处应该理解为插槽—译者注)，可是MBA却有别于寻常的机子—它的所有接口都是隐藏在一个可以90度翻开的折叠门里，这个折叠门和充电器的磁吸口都在MBA两边的下方。这个可翻开折合的门让MBA用户可以在使用MBA的时候连接其他的设备，也可以在需要的时候方便的把MBA放进袋子里而不损坏到接口。

This work tries to apply the learning process of the cognition structure defined in Cognitive Psychology to enhance or modify the development of AI, of which the learning models are almost based on trial and error style. However, this kind of learning style is definably given to the experience behavior of stimulus and response in Psychology. Thus, the relative AI models based on such style are design as an experience-adaptation system. For better ones, e.g. evolution-base algorithms, they belonged to the system with more powerful computing power to the dynamical environment. Even so, it was considered not only outside environment but also internal parameter tuning. As for the entire learning process, it has never been enhanced. That is, various original AI models are easily to be developed to their own close-form problem.

本研究企图以认知心理学之认知结构来修正自1956年以来人工智慧之发展，由於人工智慧长期局限於试误学习之低效率学习模式，然而试误学习於传统心理学定义中仅限於刺激与反应之经验行为而已，由此学习模式所建构之任何机器学习，均只能认定为经验之适应模式而已，而较进阶的种类，如演化式计算模型，也只是其能透过电脑强大的运算能力来达成所谓的动态环境下之演化式学习模式，其中演化之特色只是多考虑了外在环境的变化或内在参数的调整，而整个学习流程却没有进ㄧ步修正。

The integrative ability, organizing ability, communicative ability of trainings was deficiency. Fourthly, the power of social physical educators in Guangxi universities was so weak that it couldn't satisfy the need of specialty development. For example, the number of special teacher and the practicing ability of teachers are deficiency. The teachers that master special theoretic well and have practicing experience are deficiency especially. Fifthly, social physical practice base have not been building in Guangxi universities. And the necessary equipments of gymnasium are deficiency at the same time. Sixthly, the whole sports technology levels of new social physical students are low and hard to fit for social needing. Seventhly, the professional ideology of students is not stable enough. For example, the special concept and cognition of students are dim. The attitude for learning is not right. The most of students want to or have trend to change their profession after graduating. Eighthly, the ability of students fostered by social physical education in various Guangxi universities has a gap with the ability that students should hold for adapting the need of Guangxi employer. The special technical levels of social physical students are weak. Ninthly, in investigation of social physical personnel being demanded by Guangxi area employers, we found that few social physical personnels were demanded by business unit, the state-operated factory and mining enterprise because of being influenced by economical environment. And the more social physical personnels were demanded by social physical directors, fitness centers and each kind of sports association and so on.

这主要表现为：不够科学的课程体系，在实践性教学环节中的重视程度不够，对学生的综合能力、组织管理能力、社会交际能力的培养较为欠缺；4、对社会体育专业的发展需求这一点而言，广西各高校该专业的师资力量还略显薄弱，难以满足社会的需求，主要体现在：缺乏足够的专业教师数量、教师实践能力欠强，尤其缺乏既有较高理论素养又有实践经验的教师；5、社会体育专业的实习基地在广西各高校中都尚未建立起来，同时一些必备的体育场馆的设施也较为缺乏；6、由于入学时广西社会体育专业的学生在运动技术、技能整体水平相对较低，因此在一些专业方向的需求上难以达到满足；7、在专业思想这一方面而言，广西各高校社会体育专业的学生显得不够稳定，主要表现为：淡薄的学生专业观念，模糊的专业认识，不够端正的学习态度，甚至有相当一部分学生准备毕业后改行或有改行倾向；8、广西各高校社会体育专业培养学生目前所具备的能力与当前广西用人单位所需求的社会体育专业人才应具备的能力尚有一定差距，主要体现在：目前社会体育专业学生的专业技术水平较低，组织能力和社会交际能力较为欠缺等。9、在广西地区用人单位对社会体育专业人才需求量的调查中发现：大多数的企事业单位和国营厂矿企业因受到经济大环境的影响，基本上都不设置专职的体育管理人员，对社会体育专门人才的需求量较少，需求量较大的还是社区体育指导员、体育健身中心、各种体育协会等。

By time-varying filtering, we realize the signal selectivity and interference suppression, especially for the signals with time-varying power spectrum. It is shown herein that conventional eigenstructure based methods are lower dimensional special case of the time-frequency subspace fitting method. The closed-form array response estimation algorithms for blind source separation in wireless communication is also developed in the dissertation by exploiting the data structure of second-order statistics of the array output in the presence of multipath. The proposed method achieves array response estimation with little constraint on signal property and propagation environment such as scatters or angular spread. Moreover, the array utilized here can be of arbitrary geometry and even uncalibrated. Since the closed-form solution is obtained, no misconvergency may occur and large amount of computation can be saved. The equivalent feed model and corresponding optimization designation are proposed to realize the downlink multi-user selective transmission. By coherent and non-coherent superposition of the electromagnetical field, multiple beams can be formed using a single array, so that each co-channel user signal is transmitted in each beam and will not interfered with each other. The proposed system scheme implements the digital beamforming and the channel allocation in the base band, therefore is suitable for the utilization of the radio software technology. The feasibility and effectiveness of the proposed model are proved by the RF experiment.
