摘　　要：文章首先介绍了广播式内存及反射内存的特点、功用等,并在试验的基础上研究了二者对不同操作系统的支持程度、所构成网络的实时性、网络运行的稳定性等。得出反射内存网卡在综合性能上优于广播式内存网卡,更适合于半实物仿真系统的集成。最后通过某型号半实物仿真系统的集成及试验,验证了基于反射内存机制的半实物仿真系统的仿真实时性及仿真精度。It is presented the characteristic and function of broadcast memory and reflected memory in this paper, and research on the applying degree, real-time of network and running stabilization in different operate system on test. Then the conclusion is summed up, that the integrated performance of the reflected memory overmatches the broadcast memory and is better to be applied in the hardware-in-the-loop simulation system. Finally through test of some type the preciseness of real-time network system and its precision are approved.
