摘　　要：电容传感器具有非侵入、相应快、低成本、测量范围宽等特点,在多相流在线检测中具有良好的发展前景。电容层析成像中的传感器检测技术,是其在工业实际中得以应用的关键。近年来在传感器设计方面的研究取得了较大进展。通过传感器检测方式的改进、传感器模型参数最优化设计、传感器有限元场域剖分等改进方法获得的图像重建精度比传统的阵列传感器都有了明显的提高,但又都有其不同的缺点。综合各种方法设计的新型传感器能使图像重建的质量进一步提高。The capacitance sensor is non-intrusive, rapid dynamic response, low cost , wide measuring range and easy mounting, so it is suitable for online measurement of multiphase flow. The sensor design technology in the capacitance tomography is the key to its application in industries. Recently the studies in this field get much development. The application of the sensor＇s test way and the sensor mode optimal design and the distribution of finite element field will improve the reconstructing precision. But they all have their bad faction. Design sensor which consider all the front ways will make more improvement for the reconstructing precision.
