查询词典 emphasize

Operationally, it's never been flatter than printer, no mater how flat I brush, and it's never been more photographic than photography, no matter how hard I draw. As a result, I tend to emphasize the hand-drawing characteristic and the contrived distinctness. Technology brings us convenience and rapidity, but my work shows some reaction against it. So far, the Technology could make one touch to complete all the things, and maybe in the future it could have made everything unlabored by just thinking. However, Technological operation makes physical perceptions getting degenerated, and the crisis of primordially physical degeneration is the fierce dilemma for me.

在身体的操作下意识到平涂即使再平最终也不会大於电脑影像输出，而在物体描绘的写实感也不会大於照片的真实感，所以转而强调手绘的真实性和人为刻意操弄下的距离，对於科技带来的便利性和快速性，在我的创作中某一程度显现了对科技的反动，但是科技的操作渐渐的让身体的感知退化，目前科技可以做到 one touch 就能办到生活的一切事情，而在以后甚至只需要动脑感应就可以达到很多劳动所不及的事情，如此身体的原始性逐步降低所带来的危机感正是我自身所处的一个拉扯状态，强调身体所操作出来的痕迹。

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.
