一种用于两种成份流体成象的多电极电容层析成象系统的有限元模型和成象方法,当已知流体成份分布时"用有限元方法求出电极对之间的电容值,并用该方法计算出系统的灵敏度分布,以此作为先验知识用反投影法重建出流体成份的分布图象.

This paper describes a multi-electrode capacitance tomography system used for two component flow imaging.When the component distribution of the flow is given.the capacitance between any two electrodes can be calculated through a finite clement method.Then the sensitivity distribution of the system can also be determined by this method.The image of the flow component distribution is reconstructed by using a back-projection algorithm from the calculated sensitivity distribution.
