摘　　要：RTCA DO-178C作为研制机载软件的主要参考依据,明确规定了针对软件级别为A、B、C的软件,需要开展数据耦合分析工作以及控制耦合分析工作。在现有的RTCA标准的基础上结合已有的研究,首先对数据耦合以及控制耦合应达成的目标进行讨论,接着阐述机载软件开发全生命周期中对数据耦合和控制耦合涉及的因素,然后通过示例说明数据耦合和控制耦合中不希望出现的缺陷类型,最后分析了数据耦合和控制耦合在工程实践中遇到的问题并给出相应建议。为机载软件的研发,特别是在进行数据耦合分析与控制耦合分析时提供一定参考。RTCA DO-178C,as the main reference for the development of airborne software,clearly stipulates that data coupling analysis and control coupling analysis should be carried out for software grades A,B and C.This pa⁃per is based on the existing RTCA standard and combines with existing research to firstly discuss the objectives of data coupling and control coupling.Based on the existing RTCA standard and combining with the existing re⁃search,this paper firstly discusses the goals that should be achieved for data coupling and control coupling,then describes the factors involved in data coupling and control coupling in the whole life cycle of airborne software de⁃velopment,and illustrates the types of defects that are not expected to appear in data coupling and control coupling through examples.Finally,the problems encountered in the engineering practice of data coupling and control cou⁃pling are analyzed and corresponding suggestions are given.It will provide some reference for the next airborne soft⁃ware development,especially in data coupling analysis and control coupling analysis.
