Based on the hierarchical model of grounding grid,the limitations of the rules based testability evaluation of corrosion diagnosis are analyzed.

Based on the concept of software engineering, this paper systematically analyzes the functions and design principle of intelligent graphic supporting platform for power systems, and then proposes some design methods, such as the hierarchical model and the dissociation technique in graphic and data, which ma.

This paper compared several mechanical models with transverse shear deformation and put forward a kind of layer model assuming that shear stresses vary parabolically through the plate thickness.

Since Logistics is important for e commerce, this paper, initially routing and scheduling hierarchy model in details, discusses methods and technologies of building intelligent decision support system for logistics in e commerce, based on the analysis of certain decisive factors.

The hierarchy model of metadata in Learning-Resource Grid is constructed from the bottom layer to the top layer,and the model is consisted of Learning-Resource physical metadata,Information-Transmission metadata,Grid-Node metadata,virtual organization metadata and Learning-Resource service metadata.
