仿真中的时间和实时仿真

Time in Simulation and Real Time Simulation

从仿真中的时间概念的演变出发，对数字仿真中的时间概念和时间关系展开全面详细的探讨，在此基础上给出实时仿真的严格数学定义，同时分析实时仿真中的时间约束关系。

Starting from the evolution of time notion in simulation, the paper probes into the meaning of the time and the relation between the simulation time and real time. The exact definition of “real time simulation” is provided, and the restriction of the time is also introduced. At last, the time control strategy for real-time simulation is provided in the paper.
