In this topic, the dynamic analysis methods for piezoelectric vibrator are studied systematically based on the theoretical model, FEM numerical experimentation and FEM governing equation for given compound-mode vibrator, and some valuable conclusions are obtained. The main work accomplished is summarized as follows: 1.Elaborate the main modeling methods for piezoelectric vibrator and the significance and necessity to study the dynamic characteristics of piezoelectric vibrator which emphasize the urgency of this paper. 2.Take the bending deformation induced by piezoelectric ceramic as example, the energy transfer mechanism of electric energy to mechanical energy are analyzed; the motion and force transfer mechanism are analyzed for the longitudinal-bending vibrator. 3.Based on mode assumption and Hamilton principle, the coupling model of piezoelectric vibrator of linear USM is built; moreover, the equivalent circuit model is obtained and a coupling equation represents the relation between electric parameters and mechanical parameters is derived which provides foundation to match the vibrator and driving circuit. 4.Combine the constitutive equation of piezoelectric ceramic with elastic-dynamical equation, geometric equation in force field and the Maxwell equation in electric field and the corresponding boundary condition equation, the FEM control equation for piezoelectric vibrator of USM to solve dynamic electro-mechanical coupling field is established by employing the principle of virtual displacement. The equation lays the foundation to study the non-linear constitutive equation of piezoelectric ceramic driven by high-power. 5.Define the dynamic indexes of characteristic of vibrator and carry out variable parameters simulation by calculating the model parameters and the electric characteristics of vibrator are simulated according to the equivalent circuit model. By numerical experimentation, the working mode of vibration of vibrator and the shock excitation results of the working frequency band which provides the mode frequency to realize bimodal are analyzed. Detailed calculation of the electro-mechanical coupling field parameters is made by programming the FEM control equation.

Ralph Ellison nimbly defends the blacks' humanity with his outstanding cultural vision, and his witty use of metaphors in language. He outdid the traditional literature focusing on moralistic propaganda by Mrs. Stowe, and the naturalistic protest fiction centering on hard boiled remonstration and violence by Richard Wright, firstly by speaking highly of the 191 century classic works by such white writers as Melville, Faulkner and Mark Twain, who showed humanistic spirit affirming the blacks' humanity, and secondly by making use of the highly symbolic arid subversive language both to represent negro's humanity and whites' inhumanity, and more importantly by probing into the universal human nature by alluding to the Riddle of the Sphinx, which demonstrates, in a broad sense, the author's humanistic concern for the living dilemma of the contemporary people and also his advocatory tendency to revive the humanistic spirit of the 19th century writers.

拉尔夫埃利森通过对梅尔维尔、福克纳和马克吐温等19世纪美国经典白人作家的作品解读，赞赏了这些作家在肯定黑人人性时表现出的人道主义精神；同时运用高度象征性和颠覆性的语言，展示了黑人的人性，揭示了白人的非人性；并通过"斯芬克斯之谜"典故的阐释，对普遍意义上的人性作了探讨，体现了作者对所有现代人的生存困境的关注，从而超越了以斯陀夫人小说为代表的注重道义宣传的传统文学，以及以理查德赖特的创作为代表的注重态度强硬的抗议与暴力表达的自然主义文学，体现出回归与提升19世纪人文主义作家人道主义精神的创作倾向。

The thesis consists of six chapters. In the first, the technologies of atomic force microscopy and of the measurement elasticity of biomolecules were introduced. In the second, the validity of VSPFM was confirmed by lift mode atomic force microscopy. In this chapter, the height of DNA was measured by lift mode atomic force microscopy, which demonstrated that the method of height measurement of biomolecules by VSPFM was correct and established the foundation of the method of measurement elasticity of biomolecules by vibrating mode scanning polarization force microscopy. In the third chapter, detailed work has been illustrated on the foundation of the method of measurement elasticity of biomolecules by VSPFM. And the compressive elasticity of DNA was measured. In fourth and fifth chapters, the method was applied in the measurement elasticity of proteins. Two proteins elasticity, fibre-like protein α-synuclein and global protein IgG, were measured by VSPFM, through which the method wound its way to the application of biomolecules. In last chapter, the final part of the thesis was a summary. A conclusion of the thesis and a self-comment on my work as a PhD candidate have been made, and expectation about the further works has been addressed.

If an election is to be determined by a majority of a single vote, and that can be procured by a party through artifice or corruption, the Government may be the choice of a party for its own ends, not of the nation for the national good. If that solitary suffrage can be obtained by foreign nations by flattery or menaces, by fraud or violence, by terror, intrigue, or venality, the Government may not be the choice of the American people, but of foreign nations.
