摘　　要：抽样检测了北京谱仪(BES )漂移室(DC)将要使用的镀金钨丝和镀金铝丝的极限张力,发现同批不同轴丝之间极限张力有较大差别。测量了丝的蠕变效应,得到蠕变效应修正系数。为找出合适的镀金铝丝夹丝固定参数,对铝铜两种不同材料夹丝管需研制各自专用夹丝工具。Some results from the study of the wire for Beijing Spectrometer III drift chamber are presented. Tension test of gold plated Tungsten and Aluminum wires have been made. There is a difference in the maximum of wire tension between the different spool in a same wire production. Wire Creeping measurement has been carried out and get a correction parameter of the creeping effect. Try to find out a crimp parameter and it was needed to make special tools for Aluminum and Copper pin respectively
