叙述了航空电子系统结构的发展、航空电子系统接口的现状及其局限性，介绍了商用网络标准SCI及为满足实时应用要求而制定的互连标准SCL／RT的底层协议和性能指标，指出了SCL／RT是未来军用航电系统的核心技术和首选标准，应重视并加快对其研究。

The development of architecture of Avionics system,its architecture today,and its limifations are described briefly. The commercial network standard SCI is also introduced briefly. A bottom protocol and performance of inter linkage standard of SCI/RT which is established for real time application is described in detail. That the SCI/RT is the key technology and prefevred standard of future military Avionics system, is pointed out and great importance should be attached to it and its research quickened.
