摘　　要：以全自动生化分析仪主控软件盘转动控制软件单元为例,应用软件故障树分析法进行分析.该方法可以在设计的初期阶段对软件系统进行分析,找出关键的功能模块和可能的故障原因,从而在设计的过程中采取有效措施防止错误或故障的发生.结果表明该技术能将软件系统和控制系统很好地联系起来,从整体上考虑系统的故障问题,对分析仪软、硬件系统的可靠性设计具有良好的指导作用.Software fault-tree analysis （SFTA） can be applied at the early stages of the software development, and it helps to find out the critical module and the possible causes of the failure. So we can take some effective measures to prevent the failures from occurring when designing. SFTA was applied to one module of automatic clinical chemistry analyzer software in this paper, and it shows that the technique has the advantage of being able to link the software system and the con- trolled system at their interfaces, letting the system be analyzed as a whole, and it is a guide to the reliability design of both software system and hardware system.
