The main problems researched in the dissertation and achievements are as follows: The dissertation explains the science background and the theoretical and actual meaning of the task. The progress and the problems of the flow imaging technique are briefly explained. The advantages of electrical capacitance tomography are discussed. The paper discusses the formation and operating principle of ECT, and builds up the definite mathematical model by detail theoretical analyse, and establishes the Finite Element Model of the system by changing the finite boundary value problem of ECT into equivalence variation problem according to variation principle. On the basis of the FEM of the system, the paper builds the finite element model of the capacitance sensitivity field distribution and programs its finite element simulation software and proves the validity of the FEM of the ECT from different aspects. With the FEM and the qualitative analyse of the effect of each structural parameter of the capacitance transducer on its capability, this paper optimizes the structural parameters of the capacitance transducer, and obviously improves its capability. The compare of the simulated result with the static experimental result shows that the error of them is less than 0.9%.

A series of internal documents from the late 1970s and early 1980s shows that BAT at least thought about applying this knowledge to cigarette design. A research report from 1979 puts it thus: There are three major design features which can be used either individuallyorin combination to manipulate delivery levels; filtration, paper permeability, and filter－tip ventilation. A conference paper from 1983 says, The challenge would be to reduce the mainstream nicotine determined by standard smoking－machine measurement while increasing the amount that would actually be absorbed by the smoker. Another conference paper, from 1984, says:（5）We should strive to achieve this effect without appearing to have a cigarette that cheats the league table. Ideally it should appear to be no different from a normal cigarette...

英美公司上世纪70年代末、80年代初的一系列内部文献表明，该公司至少曾考虑过将这一知识用于卷烟设计。1979年的一份研究报告上这样说道：可分别或联合应用与设计有关的三个要素，即过滤、烟卷包装纸的通透性以及过滤嘴的通气效果，来控制焦油和尼古丁的释放水平。1983年一份会议论文也提到，关键在于，要在提高吸烟者尼古丁实际吸收量的同时，减少可被标准检测方法测定到的含量。1984年另一份会议论文说：我们应当努力达到这一效果并能在检测中蒙混过关。

This paper set out from the high order shear deformation theory at first, and utilize the spline finite point method to set up a new dynamic model of piezoelectric intellectual plate. Secondly ,a corresponding MATLAB program is written according to the theory, and has analysed the deformation of the piezoelectric intellectual plate. In the end , this paper has analysed the vibration control of the piezoelectric intellectual plate. Some results are compared with the analytic values, and have proved the rationality of the results of this paper.
