Electrochemical techniques and fractal theory were employed to study the corrosion behaviors and pits distribution characteristics on the corroded surfaces of 304 stainless steel exposed in FeCl3 solution. Fractal features of pits distribution over the corroded surfaces were observed and described by the fractal dimension. A 5.8-2.back-propagation （BP） artificial neural network model for the diagnoses of the pitting corrosion rate and pits deepness of 304 stainless steel under various conditions was developed by considering the fractal dimension as a key parameter for describing the pitting corrosion characteristics. The predicted results are well in agreement with the experimental data of pitting corrosion rate and pit deepness. The max relative errors between their experimental and simulation data are 6.69% and 4.62., respectively.

大地电磁反演算法主要分为线性与非线性两类。马奎特法、遗传算法以及模拟退火是其中具有代表性的算法。本文将三种方法的反演过程、结果及理论进行了对比研究 ,指出各自的优点与局限性 ,以及使用时应注意的相应条件。研究表明 ,马奎特法寻找目标函数全局最优的能力较差 ,只能局部寻优 ,但运算速度快 ;模拟退火法和遗传算法寻找目标函数全局最优的能力较强 ,但运算速度较慢。当对地下地电参数预先有一定程度了解 ,又可以选取比较合理的初始解时 ,可选择马奎特法 ,否则宜选用其他非线性全局寻优能力强的反演方法。

CORBA (Common Object Request Broker Architecture) provides 16 Common Object Services for distributed application development, but none of them are fault tolerance related services. In this paper, we propose a replicated object based Fault Tolerant Object Service (FTOS) for CORBA environment. Two fault tolerant mechanisms are provided in FTOS including dynamic voting mechanism and object replication mechanism. The dynamic voting mechanism uses majority voting strategy to ensure object state consistency in failure situations. The object replication mechanism can help system administrators to replicate and start up objects easily. Our implementation provides a library according to the style of COSS. With this library, programmers can develop distributed applications with fault tolerance capability very easily.

In order to improve accuracy of soil moisture inversion using remote sensing, a new thermal inertia model is proposed in this paper. The improved model needs only surface maximum temperature as the temperature parameter input instead of input of the surface temperature difference, as well as the surface sensible and latent fluxes are introduced into boundary conditions of thermal conductivity equation. Furthermore, surface soil conductive heat transfer equation of two-layer model is used to solve the soil thermal inertia so that the remote sensing thermal inertia method can be ap- plied to regions with better-covered vegetation, but usually only for the bare areas or worse vegetation covered areas. The model has been tested at several locations in the area of west Inner Mongolia. Comparing the simulation of the new model with the measurements obtained by apparent thermal inertia and by field test, the result shows that the inertia thermal model can be used to estimate soil moisture in more reasonable accuracy.

Using enterprise GIS platform, spatial databases and modern information technology, building geo-spatial information service platform of digital mine which has the features of the data exchange service, enterprise GIS services, directory services, logging services, is key technology and application infrastructure for digital mine. Based on the support of geospatial information service platform of digital mine, the professional GIS application service adapter can be developed and the application supports related to mining application system can be realized. Using high-resolution satellite remote sensing data, the mine functional partition map and geographic grids can be divided, and the geographic grid parts, status and events of important features of the surface object were investigated and defined. The system architecture and technical characteristics of integrated spatial information service platform were analyzed firstly, which guarantee service ability of digital mine.

A new accelerated method for Time-Domain Finite Element Method （TD-FEM） is presented. As the number of triangular elements mount up, compare with a Central Processing Unit （CPU） of comparable technology generation, the speed of Graphics Processor Unit （GPU） is faster and faster. Its properties make the off-the-shelf GPU suitable for accelerating TD-FEM simulations.

The geological condition of coalfield is much complex in china. With increasing in mining depth and drainage amount, the contradiction of drainage, water supply and environ-mental protection is becoming more and more serious. However, the contradiction can be solved by the scientific management of optimizing combination of drainage, water supply and environ-mental protection. The Philip multiple objectives simplex method used in this article has searched for a possible solution at the first step, and then it goes on searching to find out whether there is a weight number that can lead the solution to the biggest. It can reduce the randomness and diffi-culty of traditional weight method which determine the weight number artificially. Some beneficial coefficients are vague and the number is larger in the model of water resource dispatch. So the vague layer analysis method can consider these vague factors fully, combining the qualitative and quantitative analysis together. Especially, this method can quantify the experiential judge-ment of policy decider, and it will turn to be more suitable if the structure of objective factors is complex or the necessary data are absent. In the paper, the two methods above are used to solve the plans of drainage, water supply and optimizing distribution of water resource in the Zhengzhou mining district.
