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.

This article then takes the 2002 survey data of the elections for city mayor and councilors of Kaohsiung as an example to study voter's split-ticket voting. In particular, owing to peculiar party system in Taiwan, it examines voter's split ticket voting based on individual party and the "pan-blue vs. pan-green" party coalition. It points out that, in Kaohsiung, party coalition model performs better in explaining voter's behavior than the traditional party label. Also, this case study shows that the direction of party identification, the strength of party identification, and voter's past voting patterns are significant for voter's split-ticket voting in both party coalitions. The significances of other factors, such as voter's age, voter's provincial origins, sense of check-and-balance are different when they are applying to different party coalitions.

本文第二部分则以2002年高雄市长与市议员选举为例，探讨选民分裂投票的成因，文中特别强调因应台湾现存政党体系的特性，尝试在传统以个别政党差异研究选民分烈投票的方式之外，再以「泛蓝」与「泛绿」两类政党联盟方式进行研究，并指出后者在本个案中具有较高的适用性，同时，研究结果也显示选民的政党认同强度、方向与过去投票习性，是解释选民分裂投票行为的重要因素，其余相关因素，如年龄、省籍、制衡观念等，对不同政党联盟之持者之分裂投票行为有不同的影响力。
