摘　　要：对高气压精密漂移管的时间性能进行了研究.利用放射源和宇宙线对漂移电子的时间谱和带电粒子入射位置与漂移时间关系(r-t)及其诸影响因素进行了研究.分析了时间谱的拟合参数,并用积分法由时间谱得到(r-t)关系.In this paper the time performance of the precision drift tube at high pressure has been studied. The time spectrum of the drift electrons and the (r-t) relationship between the distance from the charged particle track to the anode wire and the drift time have been measured via both radioactive source and cosmic rays. Some factors which influence the r-t relationship have been also investigated. The fitting parameters of the drift time spectrum have been analyzed and the r-t relationship has been obtained from the drift time spectrum by using integral method.
