Because the data categoricalness rules of architecture products are embodied in theCADM described by IDEF1X, the data categoricalness rules are directly established according to the relationship, which is described by the IDEF1X, among the data entity of CADM described by the IDEF1X. Then every item of data which is in the form of CADM criterion and stored in the database is checked according to the categoricalness rules, so that the data categoricalness of C~4ISR system architecture is executed.3. The verification methods of system accessibility based on CADM are studied.
2研究了基于CADM的数据完备性验证方法由于体系结构产品中数据元素的完备性规则已经完全表现在用IDEF1X描述的CADM模型中,所以论文根据IDEF1X对CADM数据实体之间关系的描述,直接建立了数据元素的完备性规则,然后根据完备性规则对以CADM规范存放在数据库中的每条数据进行检查,以此对C~4ISR系统体系结构数据进行完备性验证。

The method of prediction on stochastical simulating 3D parameter field of rock mechanics is brought forward in this paper. Namely, rock mechanics parameters- curve obtained by known and limited conventional log materials is took as inputs of hard data;and seismic attribute data body, hydrating of mud shale and rock environmental parameters data is took as constraint of soft data. By simulating stochastically through optimizing algorithm of Sequential Gauss Simulation,dynamical data field of rock mechanics parameter of three-dimensional space are gotten, then log response of rock mechanics parameters in position of any point in space is predicted.
