The gas - particles two - phase flows in the horizontal pipe and u - beam separator were also studied in this thesis . electrical capacitance tomography ( ect ) is a new method to measure the volume distribution of solids . it is not affected by the opacity of particles 实验测量上，本文采用电容层析成象技术测量了旋风分离器内部颗粒的浓度分布，分析了颗粒在分离器锥体部分的浓度分布规律、概率及频谱特性。
