摘　　要：介绍了电磁兼容的定义、目的,设计步骤、试验项目和要求,针对机载计算机电磁兼容的特点和工程实践,提出解决机载计算机电磁兼容问题重点关注的四个方面,即电缆设计、机械结构设计、电源滤波器设计和计算机电源接地和信号接地设计。通过总结机载计算机设计和电磁兼容试验中出现的具体问题,从理论上分析问题产生的机理,提出切实可行的工程解决方法。最后强调该技术是试验性的科学,解决方案必须通过电磁兼容试验验证。EMC′s definition,purpose,design process,experimental content and demand are introduced in this paper. Four aspects （cable design, mechanical design, power filter design, and computer power ground and signal ground design） to achieve airborne computer EMC are proposed according to the characteristics and engineering practice of airborne computer EMC. By summarizing the issues appearing in airborne computer design and testing,the mechanism that the problems occured was analysed in theory. The practical engineering solutions are put forward. The solution must pass EMC test verification because the EMC technology is experimental science,the author stressed emphatically.
