摘　　要：为了安全、方便、可靠地进行微气体敏感单元气敏性实验,设计了一套微气体敏感单元实验平台,包括配气系统、反应室和检测系统。利用组态软件作为软、硬件的连接桥梁,实现了在计算机中对采集到的数据进行处理和存储。制备了SnO2敏感薄膜,通过实验平台测试测得灵敏度约75,响应时间约2 s,回复时间约200 s.实验验证了该实验平台的可靠性。A safe,convenient and reliable gas sensitivity test platform for micro-gas-sensitive element was developed,including the gas distribution system,reaction chamber and detection system.Detection system was designed with configuration software as a bridge to connect the software and hardware.This system carried out the data-processing and datastorage by computer.The reliability of gas sensitivity test platform for micro-gas-sensitive element was proved using SnO2 thin film prepared by sol-gel.The test results of the platform were that the hydrogen sensitivity was about 75 and the response and recovery time were about 2 s and 200 s,respectively.
