摘　　要：同一实体的不同分辨率模型的并发运行经常出现在分布交互式作战仿真中。研究了分布式仿真中不同分辨率模型并发运行时的若干关键技术。提出了同态属性和同态交互的概念;研究了多分辨率模型并发运行时的一致性维护问题,给出了多分辨率模型的一致性维护算法;研究了并发交互冲突的解决方法,包括:加锁方法、冲突检测法和面向模型的方法等;分析了同态交互对仿真结果的影响,给出了处理同态交互的基本原则。The parallel implementation of multi-resolution models （MRMs） is often encountered in distributed interactive combat simulation. Some key techniques on the parallel implementation of multi-resolution models were researched. Two new concepts, named morphism attribute and morphism event were proposed. The problem of consistency maintenance when multi-resolution models were parallel implemented was researched and a new algorithm was proposed. Then the problem of interaction conflict in MRM was researched. To solve this problem, three methods were given, including mutex locking, conflict detecting and model-oriented method. The affection of morphism interaction to simulation result was analyzed and some basic principles to deal with this problem were given.
