摘　　要：通过利用DS-Ⅲ型电子束实验仪进行电子荷质比测定的实验现象和实验数据的分析,明确了磁聚焦法测量电子荷质比实验中电子束螺旋线起点位置的不确定性,并提出等效起点位置的概念。The experimental phenomena and the experimental data of electron beam electron charge mass ratio measurement were ana- lyzed. DS-Ⅲ type experimental device has been used to finish this measurement by using magnetic focusing method. The experiment of electron beam spiral cleared starting position uncertainty and the concept of equivalent starting position has been put forward.
