Low temperature ordering of FePt thin films has been achieved by using a thin equiatomic AuCu underlayer.
提出并利用相干生长的多层膜中有序-无序转变过程的彼此关联作用,借助AuCu缓冲层的低温有序化,降低FePt薄膜的有序转变温度200℃以上,为FePt薄膜的低温有序化开劈了一条新途径;制备多层膜,退火形成有序相FePt纳米颗粒分散在Ag基体的复合结构,比FePt/Ag共溅射或合金多层膜方法的退火温度明显降低;通过缓冲层Ta控制FePt的粗糙度和晶界密度,同时界面附近Ta、Pt发生化学反应,两者共同促进薄膜内Pt原子的有效迁移,从而加速FePt有序化;进一步,在Ta和FePt之间插入Bi薄层,强化Ta、Pt的扩散,在更低温度下形成高矫顽力的有序化FePt薄膜且FePt晶粒之间交换作用大大减弱;发现MgO薄膜作底层,可控制与MgO晶粒尺寸大致相当的临界厚度以下的FePt有序化薄膜的(001)取向,同时,MgO和FePt的相对厚度显著影响(001)取向FePt的有序化。

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。
