In the part of the vibration experiments and analysis, firstly, used the simple-beam theory to estimate the natural frequency of the beam of the 20-headed computerized embroidery machine.secondly, measured the beam of its low rank natural frequency, the beams horizontal vibrating acceleration amplitude, speed amplitude and the displacement amplitude in different rev and different turn parts. Found that it is sympathetic vibration, which bring on the thread-broken rate rise rapidly. On this base, established the finite element analysis modle of the vibrating beam, and took on hamonic analysis and modal analysis with the mold. The rusult of test and analysis offer the basis for farther improvement of the computerized embroidery machine.

振动分析部分，首先由简单梁理论出发，对横梁的固有频率进行估算；接着通过测振仪器对20头电脑刺绣机横梁进行了试验模态分析和不同工况振动测试；获得了横梁前四阶固有频率和模态振型，以及在不同工作转速、不同回转部件下横梁振动的加速度幅值、速度幅值和位移幅值；找到了横梁振动加剧的原因——共振；在此基础上建立了符合实际情况的横梁有限元模型，对模型进行了模态和谐响应计算，证实了模型的可靠性，为下一步的改进设计提供了依据。

The results of research on the factors affecting titanium tannage show that high concentration NaCl medium has larger negative effect on titanium tannage. When the NaCl concentration exceeds 5%, the titanium tanning action is reduced rapiddly. Traditional NaCl pickling is unsuitable for titanium tannage, tanning in water medium directly, the best tanning effect can be obtained, so titanium tanning can not only eliminate chrome pollution, but also diminish salt pollution. The optimum tanning conditions for HPZ-Ti tan liquor are pH3. 5, TiO〓 offer of 7. 5%(based on the weight of 65% moisture pelt), the best Bascity of tan liquor is between 30% and 50%.

以HPZ—Ti鞣液为基础，研究了不同鞣制介质，鞣制pH值，鞣剂用量和浓度，鞣液的碱度，不同提碱剂，不同的预处理和后处理等因素对钛鞣的影响，结果表明：高浓度的NaCl溶液介质对钛鞣有很大的负面作用，当介质NaCl浓度超过5%，革内钛的结合量和革的Ts明显降低，传统的高浓度NaCl浸酸工艺不适合于钛鞣，在水介质中直接鞣制效果最好，所以钛鞣不仅消除了铬污染而且大大降低了盐的污染。

Network game industry what course to follow, it is to be in thearchy is blatant in trend be on the wane, still leave in fight to the bitter end give a new way, probably who said to also do not calculate, even if be Chen Tianqiao, Shi Yuzhu and fourth Lei, set sth afoot from 2009 case, actually game manufacturer also realised this, the attempt of blame mainstream game that takes out oneself and other sport company start associated operation, the attempt publicizes his game ceaselessly in He Sui film, the attempt puts commerce on advertisement in his game... the some day that will come probably, all Chinese, see TV need not pay again close inspect cost, play game to also need not spend one wool money really, be like like ad was being made in TV, game world also so not will dinkum, also will evolve to offer company level to apply in game by company level user, for instance inside activity of buy advertisement, sales promotion, OEM is bound, even need not which show card to cannot be in what and so on upgrades in game " limitative class " sale, perhaps friends read this meeting to feel now is an incredible story, but in game world, I think truly, everything is all possible!

网络游戏产业将何去何从，是在众神喧嚣之中走向衰落，还是在血战到底中开出条新路，或许谁说了也不算，哪怕是陈天桥、史玉柱和丁磊，从2009年发轫起，其实游戏厂商也认识到了这一点，拿出自己的非主流游戏尝试和其他游戏公司搞联合运营，尝试在贺岁电影中不断宣传自己的游戏，尝试在自己的游戏中投放商业广告……或许将来的某一天，所有的中国人，看电视不用再付收视费、玩游戏也真的不用花一毛钱，就好像电视里打了广告一样，游戏世界也将不那么纯粹，也将演变成由企业级用户在游戏中提供企业级应用，比如内置广告、促销活动、OEM捆绑，甚至于不用哪家的显卡就不能在游戏中升级之类的"限制级"销售，也许现在朋友们读到这会觉得是天方夜谭，但在游戏世界里，我确认为，一切皆有可能！

This thesis deeply researches the J2EE security strategy on the application tier of enterprise system. The security strategy predigests the information security model and meets the security requirements expediently. But there are some disadvantages when the security requirements become more complex. The expositive security on the Web-Tier can not offer more information for authentication; there is no authentication for EJB-Tier to use, make the EJB-Tier depend on the Web-Tier; J2EE uses database or application server to manage the role information. Use database to manage the role information will increase the complex of enterprise application, and the way of application server will reduce the ability of migrate other J2EE platform. To solve these problems, the thesis designs an improved security strategy model.

本文从企业级系统应用层安全的角度出发，深入研究J2EE多层体系结构的安全策略模型。J2EE提供的安全策略简化了系统的信息安全模型，能够很方便地满足基于J2EE的分布式应用系统的安全需求，但是在面对更加复杂的安全需求时，J2EE安全策略在验证授权和角色管理中还存在不足之处：其在Web层的声明式验证机制无法为用户提供更多验证信息，可扩展性较差；在EJB层缺少业务逻辑层可供采用的验证机制，而是借助于Web层的验证机制，其耦合程度较高有悖于业务逻辑分离于表现逻辑的原则；在角色管理方面，J2EE采用数据库或者应用服务器来管理角色信息，其中，数据库管理角色的方式增加了应用开发的复杂度，应用服务器管理角色降低了系统的可移植性，两者都具有片面性。
