摘　　要：DO-178C是在民航领域对机载软件进行适航认证的标准。首先,对DO-178C标准中提及的软件等级分类方法进行了阐述;其次,介绍了软件生命周期过程、软件过程要实现的目标;然后,阐述了不同等级软件生命周期过程与目标的关系;最后,得出了结论,即4个等级的软件都有独立性要求,但软件在开发过程、配件管理过程、合格审定过程中的要求基本一致,最能区别不同等级的严酷度要求在剩余的几个过程中体现。The DO-178C standard is a standard for airworthiness certification of onboard software in the civil aviation field.Firstly,the classification of software levels mentioned in the DO-178C standard is outlined.Secondly,the soft⁃ware lifecycle process and the goals that the software process aims to achieve are introduced.Then,the relationship between the lifecycle processes and objectives of software at different levels is elaborated.Finally,the conclusion is drawn that all four levels of software require independence,but the requirements for software development,configu⁃ration management,and certification processes are basically the same.The strictness requirements that best distin⁃guish different levels are reflected in the remaining processes.
