摘　　要：在矩形循环流化床底部固体浓度的测量中首次采用了迭代电容层析成象方法,比通用的线性逆映射方法明显提高了成象质量。通过层析成象分析得到了床层中固体浓度分布、平均固体浓度随时间的变化和频谱特性。Iterative image reconstruction of ECT was for the first time applied to the measurement of solids concentration in the bottom region of CFBs. Significant improvements were achieved over LBP. Solids concentration profile, time variation of average solids concentration, and frequency spectra were analyzed via ECT data.
