英文摘要：
Process tomography （PT） is a widely available and flexible imaging technique that is a new measuring method applied in measuring multi-phase flow. This paper uses a new method --COMSOL to analysis the electrical capacitance tomography of research and the simulation. First of all, this paper introduces the electrical capacitance tomography system structure and the electrical capacitance sensor mathematical model; In addition, the paper builds a model with COMSOL, divides the mesh and simulates the model; Finally, the paper has analyzed influence of the different dielectric constant and medium to the imaging quality.
