摘　　要：针对军事工程真三维连续特性及其实体表达的不确定性,给出了军事工程实体信息及数据描述方法,目的是为视景仿真、毁伤建模与仿真等应用领域提供服务。在表达军事工程地理实体认知的基础上,提出了实体信息描述要求;以概念建模为顶层设计,从地学、几何、拓扑、材质等层面进行抽象,给出了军事工程真三维空间集成建模方法;抽象点、线、面、体等实体,给出了军事工程实体模型集成表达方法,并以UML类模型表达了军事工程实体的数据模型。该方法应用于军事工程实体建模,能够较好地表示军事工程三维空间对象,并能有效支持围绕军事工程实体的各种拓扑操作和军事应用。For military engineering＇s true three-dimensional continuous characteristics and its uncertainty in entity expression,entity information and data description method is given,which is to provide services for visual simulation,damage modeling,and other applications.On expressing geographical entities in knowledge to military engineering,descriptions requests was proposed in entity information.To conceptual modeling as a top-level design,integrated modeling method was given in the true three-dimensional space,learning from the ground level,geometric level,topological level,material level,and others.An integrated way of expression was given to military engineering entity model,Abstracting point,line,surface,body and other entities,and then data model was expressed to military engineering entity by UML class model.This method applied to military engineering entity modeling,could express 3D objects of Military Engineering,and could effectively support various topology operation and military applications around the military engineering entity.
