用电容传感器的三维有限元模型，分析了８电极电容层析成象传感器灵敏度的三维分布。用重建图象评估了传感器轴向敏感空间的大小。讨论了将三维敏感场近似成二维场所带来的误差。
Using the three-dimensional finite element model of capacitance sensor, the three-dimensional distribution of the sensitivity of 8-electrode capacitive tomography sensor was analyzed. The reconstructed image was used to assess the size of the sensor’s axially sensitive space. The errors caused by approximating three-dimensional sensitive fields into two-dimensional places are discussed.
