摘　　要：利用宇宙线分别测量了两个单元尺寸为14mm和16.4mm充He/C3H8(60/40)气体的小单元漂移室模型的性能,包括空间分辨,dE/dx分辨和单元效率。测量结果表明两个漂移室模型的性能没有明显区别。The spatial resolution, dE/dx resolution and cell efficiency of two prototypes of small-cell drift chamber filled with He/C3H3(60/40) with cell sizes of 14.0 mm and 16.4 mm were measured using cosmic rays respectively. The results show that the performances of the two drift chambers are almost equivalent.
