摘　　要：文中设计了一种基于LabVIEW控制步进电机的气体自动采样装置。论述了该采样装置的工作原理、软硬件结构。运用该采样装置匹配电子鼻对P25光催化降解甲醛的全过程进行监测。结果表明该采样装置不仅具有自动、定体积气体采样功能,而且稳定、可靠、成本低。In this paper,an automatic sampling system for gas was presented,whose core component was stepping motor controlled by LabVIEW program. The working principle of the sampling system, its hardware architecture and its software program were discussed. The whole process of photocatalytic degradation of the formaldehyde with P25 was tested with this sampling system and electronic nose. The results implied that the designed sampling system not only owned the abilities of automatic and alternative volumes, but also was stable, reliable and low-cost.
