摘　　要：推算定位技术是分布交互仿真系统缓解通信量及实时性问题的重要手段 ,但目前的推算定位算法采用统一的阈值 ,没有区别对待远距离实体与近距离实体 ,造成通信资源的浪费 .提出多阈值推算定位技术 ,根据实体的兴趣度把责任域划分成若干子责任域 ,同时本地实体进行多级推算 ,每级推算对应不同的子责任域及阈值 .多阈值推算定位技术很好地解决了近距离实体的行为失真与系统通信量之间的矛盾 。The technique of dead reckoning(DR) gives a way to reduce the network communication costs and network latency in distributed interactive simulation. But each of the present algorithms of DR owns only one threshold, so it could not differentiate the entity in the beyond from the entity in the nearby. The technique of DR with multi threshold discussed in this paper divides the DOR into several child DOR. Each of local entities reckons differing from the child DOR with different threshold. The technique of DR with multi threshold resolves the conflict between the behavior distortion of the entities nearby and the network communication costs, and it works well.
