A modified slaking model is proposed based on test results and Shen Zhujiang slaking model,and it is validated by the test results to confirm the capability of simulating slaking deformation and dilatancy of excavation materials.

By employing the evolution model of one-dimension signals, an evolution model o f the image is constructed in a generalized space, and the relationships between the parameters of the proposed model and the physical variables of the image ar e given, on the basis of which a structural information model of the image is pr oposed, H (Tran) being defined as the structure entropy of the image.

Present an evolution model to record the process of creating,developing,implementing,expanding and destroying a software component(include various models and codes).

In this paper,ecology theory was used to investigate the structure and evolution of interagency information sharing system of E-Government,and both structure model and evolution model for this system were proposed.

The phase diagram of the LaF 3-NaF system is optimized by using the new modified quasichemical model in the pair-approximation for short-range ordering and calculated with CALPHAD (Calculation of Phase Diagram) technique.
