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.

In view of this point, Lu Ling's novels are of value, because strong intellectual complex is embedded in his novels describing either workers or peasants, in which the character's spiritual dynamics receives utmost concernViewing from the perspective of the intellectual quality-freedom, enlightenment and reflection, this dissertation seizes up the traits of intellectual character of Lu Ling's novels in 1940's, in an attempt to reproduce the sheen of his novels, and also to take a glimpse at the psychological journeys of the youth generation at that ageThose characters in Lu Ling's novels behave unbridledly all the way through their life journeyo They rebel against all the absurd things, declare war on tradition, family and newly rising authority, also anatomize themselves They resort nowhere Their life is closely linked to tramp It is right during the course of tramp and rebellion that they realize themselves, look for freedom and luminosity, and achieve real contact with people; they have enjoyed the unrestraint to their heart's content as well as experience torture from various forces in heartLu Ling's novels are affluent in connotation This dissertation only studies from the perspective of intellectual, the topics among which like: freedom, tradition, individual and collective are still worthwhile studying up to now.

从这一点出发,路翎的小说很有价值。他的小说不管是描写工人还是农民,都带有浓重的知识分子情结。他的关于知识分子的小说,更是极力关注人物的精神动态。本文从现代知识分子品质的角度——自由、启蒙与反思,打量路翎四十年代小说中的知识分子人物的特质,企图在这种论说中使路翎小说的光彩重现,也从中窥视那一代青年在那个时代的心路历程。他小说中的那些人物,在人生的道路上一路狂飙过去。他们反叛一切不合理的东西,对传统、家庭、新生的权威开战,也对自己身上旧的、暧昧的因子毫不留情。他们在哪里也停留不下,他们的人生和流浪紧密地联系在一起。在这个不断的流浪和叛离中,他们认识自己,追寻自由、光明,力求与人民的真正接触。也正是在这个背叛—寻找的过程中,他们享受了狂飙的酣畅淋漓,也体会到了内心各种力量撕裂的痛苦。路翎小说的内涵很丰富,本文只是抽取了知识分子这个角度进行研究。当中的一些命题:自由、传统、个人与集体在今天还是很有研究价值的。
