Based on the similarities betwcen production system and human thinking,this paperintioduces a hypothesis concerning finitely related clusters in the human thinking process,and designs a distributed member systcm modcl,which is based on this hypothesisand supports cooperativc AI problem solving.

The thermodynamical properties of the two dimensional square lattice and the three dimensional simple cubic lattice transverse Ising model with spin - 1/2 are investigated within the framework of the finite cluster appraximation.

This paper gives a new method the finite block method, which may lower 3 dimensional problems to 2 dimensional ones, so a great deal of computer internal memory and computation time are saved.

For the engineering structure analysis, a new method -the finite block method to cope with the structure which has regular geometric shape and boundary condition is set up.

This paper gives a new method,the finite block method, for treating the melt flow of three non-Newtonian dimensions in the flow channel of sheet die.

Area-judgment method for complex finite rock blocks based on three-dimensional network simulation of fissures;

With the program,all the finite rock blocks can be found out with free face exposed on excavation face.

,propoundarea-judgement method for finite rock blocks,introduce two dimension network ofcrack into distinct element model of underground .
