基于双极性脉冲电流技术的电阻层析
提出了一种利用双极性脉冲电流源作为激励源的电阻层析成像硬件系统设计的新原理,该方法削弱了采用常规直流激励源时带来的介质电极化效应。关键词:电阻测量;层析成像;传感器;两相流Abstract : A novel ERT system has been developed with new design principle. It selects the bi2directional current pulse as its ex2 citing source , which weakens the polarizational effects at the electrodes.Key words : resistance measurement ; tomography ; sensor ; two2phase flow
