级微波四端网络的噪声参数计算 - This paper describes a reconstructive algorithm which is based on network theory for electrical capacitance tomography technic . there are twelve electrodes in the system . the permittivity distribution of flow with two components within a pipeline is reconstructed . assume the permittivity distribution of the region to be reconstructed . then whole measured area is discretized into a network composed of capacitance . the measurement circuit which contains a pair of source electrode and detecting electrode is taken as a four - terminal network . the across admittance of the four - teminal network is proportional to the capacitance between the source electrode and the detecting electrode . modify the distribution of the permittivity according to the difference between the calculated capacitance and measured capacitance . the experimental results show that this algorithm is effective and can coverge
本文描述了一种用于两种成份的流体成像的12电极电容层析成像新方法.该方法基于电路的网络理论，首先对重建区域假定一个介电率分布，用电容网络作为离散化模型，将每一个源电极和探测电极对组成的测量电路看作一个四端网络，该四端网络的跨导与源电极和探测电极之间的电容值是线性关系，这个电容值和测量得到的电容值之间存在误差，根据这个误差对修正介电率分布.通过对不同介质分布作的模拟实验结果，证实了该算法是有效的，收敛的
