摘　　要：　介绍了合肥国家同步辐射实验室在原有纵向耦合阻抗测量系统基础上根据国际流行的同轴线原理改进的新纵向耦合阻抗测量系统的基本原理、系统组成和初步测量结果。对"药丸形"腔的阻抗的实验测量结果和阻抗计算程序计算结果基本相符,验证了该系统的有效性。In this paper the old longitudinal coupling impedance measurement system of National Synchrotron Radiation Laboratory is reviewed briefly. Considering the deficiency of the old system and advance of measurement apparatus, the improvements of measurement principle and hardwares were made. The measurement principle, system hardware configuration of new improved measurement system based on coaxialwire method is presented in details. The measured impedance is agreement well with the calculated impedance by ABCI code, and the performance of the new system was demonstrated.
