摘　　要：本文介绍了一种应用广泛的火灾探测和火灾警报的测试系统。该系统中包含标准烟箱,离子烟浓度计(MIC),光学密度计和气溶胶发生器。文中分析了系统测试的重复性。研究发现气溶胶发生器的升烟速率,气溶胶速率,样品摆放位置都是影响该系统性能测试指标的因素。本文对该系统开展的基础性研究有助于相关实验室,产品制造商和标准修订人员的工作开展。This paper introduces a widely used testing system for fire detection and fire alarm, which includes smoke tunnel, measuring ionization chamber（MIC）, obscuration meter and aerosol generator. It analyzes the system testing repeatability and concludes that the rate of increase of aerosol density, the flow rate of aerosol and the position of sample will affect the testing result of the system. The fundamental research of the system in this paper may be beneficial to the related work of testing laboratory, system manufacturer and standard revision personnel.
