摘要
本文分析了两相流电容层析技术中目前存在的问题,研究了基于分组BP网络的成像方法,提出了成像的网络模型及其实现步骤。实验结果表明,该方法能够快速和较高精度地重建出两相流体的断层图象。
? This paper discusses the problem of two-phase flow electrical capacitance tomography . A neural network method for electrical capacitance tomography is proposed. A neural network model for image reconstruction and its realization are studied. Experimental results illustrate that the method is effective and accurate for image reconstruction.
