It is presented that behavior of simulation is abstracting and synthetic cognizing to the investigating object . simulation system must be constructed as a monomorphism of investigating object with comparability of mathematics and geometry . reflecting theory of information model presented by the author is used as guidance of ideal 在论文中，作者回顾了仿真发展历史，分析了rtdivs信息反映本质特征，认为：仿真系统建立是以人为信息宿主的信息模型反映实例；从理论高度阐述了仿真系统建立的思想基础，指出：仿真行为是研究对象的抽象与综合认知，仿真系统应以数学特性相似以及几何特性相似为依据，构成研究对象的同态系统。
