摘　　要：根据谐振腔的微扰理论,采用小球微扰法,为射频加速器建造中的冷模测量建立了一套自动测量系统,实现了高精度、批量自动化测量的要求。并用该系统对一台设计中的射频四极场(RFQ)加速器冷模进行了测量,验证对RFQ的设计要求。A cold model measurement system of the RFQ resonant cavity is introduced, which can measure the field distribution of cold model through bead-pull measurement. The system has two advantages. One is that people can write a script and make it automatically accomplish all the procedures, including pulling and positioning the bead and all the data acquisition. The other is that the precision of bead positioning is improved much by using the step-motor. Some measurement results of a D^＋ RFQ cold model are given.
