Uncertain singular systems are transformed into the form of restricted equivalence by a nonsingular linear transformation. By the method of Lyapunov function, a new terminal sliding mode control strategy based on the form of restricted equivalence is proposed for the first time, and the hypersurface of a special terminal sliding mode is given. A terminal sliding mode controller is designed correspondingly such that the motion of sliding mode can be guaranteed and the systems state variables can converge to the equilibrium point in a finite time.

通过非奇异线性变换把不确定奇异系统变换成受限等价形式，利用Lyapunov函数方法，首次提出了一种新的Terminal滑模控制策略，给出了特殊的Terminal滑模超曲面，设计了相应的滑模控制器，实现了滑模运动，保证了系统状态变量在有限时间内收敛到平衡点。

The second chapter analyzed its phylogeny, contrasted and classified the conformation in terms of the ancient period of external and internal and the modern times. The third chapter concluded the mainstream trend of transformation in contemporary days and sum up the character.

From the point of environment theory, the last chapter studied its meaning and function to surrounding quality, further advanced the ingression from a architectural element to a broad conception in city design.Combined with excellent examples of famous architect home and abroad, this thesis push forward its research to the skills and techniques of entrance space design.

While library resource sharing is shifting to the new networking environment era, it is also in face of a lot of new challenges and"Access versus Assets"is becoming the new theme of the resource sharing in this new networking era, based on this point this thesis studies the development and the transformation of the resource sharing both in practice and in theory in the networking environment, particularly focus on a serial of issues, including the construction of resource sharing system, digital information resource, digital library, interlibrary loan, document delivery service and collection development etc. The writer also analyzes the coexsitence of the traditional resource sharing and modernizational resource sharing and the relationship between them in 21st, explores the revolutionary changes of resource sharing as the"Assets"model is driving to the"Access"model, discusses the development of specific collection for a single library and how to construct a seamless integrated information resource system in the networking environment, systematically studies and introduces the new organization model of resource sharing, especially emphases that document delivery is the key of the success in resource sharing, and finally tries to outline the main trends which will influence resource sharing.

本文立足于网络环境下资源共享的新主题：存取与拥有，研究和分析了网络环境下资源共享及其体系建设，包括电子信息资源、数字图书馆建设、馆际互借、文献传递服务、文献资源建设等几方面在理论和实践中的发展和变革；论述了21世纪初网络环境下传统型和现代型两种层次并存的资源共享；探讨了文献资源建设从"拥有"模式到"存取"模式的重大转变、特色馆藏建设和无缝一体的网络信息资源体系的建设途径；较为全面、系统地研究和介绍了网络环境下资源共享的新型组织模式的形成及其特点；强调了文献传递是实现资源共享的关键；并试图准确把握网络环境下资源共享研究和实践的发展趋势。

The formation of martensite is accomplished by the immigration of well-defined glissile interface (121)fcc type and its misfit dislocations can produce the lattice invariant deformation on the basis of phenomenal theory of martensitic crystallography, however, LID is retarded slightly after the migration of interphase (121)fcc, i.e.a thin plate-like zone exists without LID in martensite near the well-defined interface. When the temperature reduces to the Ms point, the lattice parameter of austenite matrix is √3/2 times that of the martensite without LID. This critical condition for spontaneous transformation agrees with that the stack fault energy in matrix is less than zero according to Olson and Cohen's nucleation model.

通过模型分析表明：fcc/bcc马氏体形核与长大过程是通过(121)fcc型择优界面推移进行的，界面上的错配位错可以完成马氏体晶体学唯象理论要求的点阵不变变形，但LID要稍滞后于界面迁移，即在马氏体形核与长大过程中推移界面新相一侧存在一未发生LID的新相薄区；当相变温度达到马氏体相变点Ms时，母相奥氏体与这一薄区的晶格常数比为√3/2，这一几何条件和Olson-Cohen形核模型中要求扩展位错层错区界面能γ≤0是等价的。
