RESULTS:① No obvious sight defect was detected with the quantitative detection of automatic sight apparatus.② ECT cerebrospinal fluid imaging thought that proximal frontal sinus of right cerebral frontal lobe was the leakage, and the liquid glucose in nasal cavity was quantitatively confirmed to be cerebrospinal fluid.③ Cranial CT showed that cleft could be observed in bilateral frontal lobe and lateral ventricle, low-density gas shadow could be observed in cisterna ambiens, cortex of frontal bone was discontinuous, and bone matrix was trapped.④ ECG showed that right forehead and temple had irregular slow wave, and attack of θ wave. Brain topographic mapping showed that the δ power value of right forehead was increased.⑤ EPQ: The scores of extraversion-introversion, neuroticism, psychoticism and lie were 55, 55, 80 and 50 respectively;⑥ MMPI: The code showed a mode of 69/96, indicating that the brain organ tended to paranoid schizophrenia.

But ECT technology has the following characteristics: 1 the measured capacitance and its change induced by the measured material concentration variation are very small, but the stray capacitances of co-axial screening cable and CMOS switches are relative very large, so the capacitance detecting is easily affected by the stray capacitances, 2 the electric fields in the sensors detecting region is affected by the permittivity distribution, non-uniformity of the space responsive sensitivity is very high, and the image reconstruction is undetermined.

但由于ECT技术中，首先所检测的微电容量及其因物流相含率的变化所引起的变化量很小，而由相关的连接同轴屏蔽电缆与切换CMOS开关所引入的杂散电容远远大于测量电容，微电容的测量容易受杂散电容等的影响；其次，多电极电容传感器测量区内的电场受介质分布的影响，且测量区内的空间响应灵敏度极不均衡，其影响图像重建的不确定性；其三，ECT中的图像重建，由于其是一个欠定问题的求解，在迭代求解方法中，迭代的初值影响迭代过程收敛到近似解的速度；其四，对于气/固两相流应用而言，由于ECT系统在线标定的难以实现，管壁磨损等因素的影响制约该技术应用于生产工艺中气/固两相流的长期连续检测。

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%.
