摘　　要：本文给出了ＢＥＳ桶部簇射计数器工作特性的一些测量结果。用５５ＦｅＸ射线源测量了工作气体的气体放大特性曲线和气体入出口的坪特性曲线，测量了输出脉冲电荷量的稳定性。用宇宙线μ子测量了桶部簇射计数器不同并联单元的坪特性曲线。用Ｂｈａｂｈａ散射测量了桶部簇射计数器的能量分辨与位置分辨。Some experimental results of operating properties of the Barrel Shower Counter in the BES are given. The gas multiplication characteristic curves and the plateau characteristic curves from gas inlet and outlet of the BSC are measured using 55 Fe X ray source. The stability of output pulse charge is reported. The platean characteristic curves for different parallel cells of the BSC are measured with the μ particle in cosmic rays. The energy resolution and position resolution are presented from the Bhabha scattering. (
