摘　　要：过程层析成像技术(Process Tomography,简称PT)由于其非侵入与可视化等特性在医疗与工业过程等领域有广泛的应用前景,已从实验室研究进入工业应用研究阶段。本文介绍了基于光学、电学、超声以及核子敏感性原理的PT技术与多模态PT技术,并简述了PT技术在多相流测量中的应用研究方向。Process tomography （PT） has a great perspective in medical detections and industrial processes due to their non-intrusive character and visibility, and the research to PT has entered the sate of industrial applications. The operating principles of the P＇r that are based on optical, electrical, ultrasonic and nucleonic sensing techniques, as well as that of the multi-modality PT are introduced along with their applications in multi-phase flow measurements.
