摘要：
Stock market is complicated dynamic system affected by many factors. To model it, many methods have been proposed. But those methods cannot solve this problem very well. In this paper, from analyses the mathematic description of stock market system, a new method based on new evolutionary neural network is proposed here. In this new evolutionary neural network, the traditional BP algorithm and a new bionics algorithm, immunized evolutionary programming proposed by author 1 is combined. In order to verify this new method, the stock market data of Shanghai market in 1996 is used. The results show that, our new method is very good to real practice.

摘要：
Geodetic deformation severely affects the development of the oilfield and probably causes casing damage or abandonment of injection wells and producers. Therefore, it is meaningful to survey and study three-dimensional geodetic deformation in the process of the oilfield development. In order to study this issue, 11-year long term surveying of three-dimensional geodetic deformation has been carried out while developing Naner area in Daqing oilfield. Basic rules of 3-D geodetic deformation have been obtained through surveying. Results show that production and injection under high pressure may cause the changes of surface elevation, and geodetic deformation correlates with simultaneous formation pressure. Precautions and relative technological measurements have been put forward in the waterflood development in Naner region and provide theoretical guidelines for the production and casing preservation of the oilfield. Finally, surveying results are interpreted by porous elastic theory. Mathematical model to calculate 3-D geodetic deformation is put forward in the course of the oilfield development.

摘要：
The optimization of mine ventilation system is a very complicated combination optimization. Ant colony algorithm proposed recently is a very good method to solve complicated combination optimization problem. Considering the essence of optimization of mine ventilation system, the ant colony algorithm is introduced here to solve the problem of mine ventilation system optimization. The detailed process of ant colony algorithm to optimization of mine ventilation system is described in this paper. At last, a mining engineering example is used to verify the effect of this new method. The results show that, ant colony algorithm is a very good method to complicated combination optimization problem. It not only can solve optimization of ventilation system, but also can solve the similar problem of scheme optimization.
摘要：
A statistical model is proposed for the analysis of fatigue crack growth, based on the theory of fracture mechanics and stochastic process. The fatigue growth process is approximated as a diffusive Markov process. The associated backward Fokker-Plank equation and boundary conditions are written, and the distribution of crack growth time under a given crack size is obtained by using an Eigenfunction method. The sought distribution is expressed in the form of a convergent infinite series. Two examples are presented to illustrate the application of the method. The predicted results seem to agree with the experimental data.
摘要：
The objective function of the optimization parameter back analysis is a very complicated nonlinear multiple hump function. To solve this problem, the traditional optimization methods have some problems, such as the result relying on initial value, easy to fail, while the global optimization method-Evolutionary Algorithm can solve it very well. But the efficiency of the generally used Genetic Algorithm (GA) is very low. To overcome the GA's problem, a new bionics algorithm-Immune Evolutionary Programming (IEP) which combines Artificial Immune System (AIS) and Evolutionary Programming (EP) is proposed. At last, one numerical example and one a real. engineering example are used to verify calculating effect of the proposed algorithm. The results show that, to one problem, this algorithm can identify the suitable parameters of surrounding rock mass when only the displacements are known. And the calculating efficiency and effect are all good compared with other methods. Then this algorithm is more suitable for parameters identification problem and can be applied in real practice.

摘要：
Combining the theory of porous flow and elastic-plastic mechanics and considering the interaction of coal-bed methane and coal-mass, a mathematical model for the movement of coal-bed methane and the numerical method were established. Through dispersing the equation of coal-bed methane porous and coal distortion, we obtained a functional analysis equation, and educed the coupling solution by finite element method. Finally, a calculated example was presented in this paper.
