In allusion to form images with the same context, a sepcial method which uses the same context of form images as 2D model and the differentia as moving parameters is proposed according to the model-based coding with moving image.

A basic model of reaction dynamics consisting of 60 chemical reactions among 19 active compounds,and a simplified model including only 27 reactions were developed for seeking reaction mechanism.

The key of the research in Collar's Pattern Auto-generation Expert System is to establish a collar's 3D basic model and to get the 2D structure and pattern of the collar on the basis of this.

The results show that in cases of inhomogeneous topologies with lane droping or high on-and off-ramp volumes the basic model has significant dev.

A formalization description method, basic-element model is presented to describe matter element, affair element and relation element in CPCC.

New composite foundation model for portland cement concrete pavement;

Based on the different viscoelastic foundation models, the stationary stochastic seismic responses of the interaction system of structure and foundation have been calculated.

Some assumptions in the study of interaction of soil and base are firstly looked back,and the result that the elastic continuous medium model can reflect the nature of soil well is obtained by analyzing several elastic foundation models.

Taking the amplification coefficients of peak acceleration and its corresponding Fourier amplitude spectrum as main factors,the measured results of existing typical shaking table tests were analyzed and the vibration behaviors of foundation model were compared in terms of boundary effect,height of foundation model,moisture content of soil and numbers of input seismic waves.
