Abstract: From the lattice orientation of a sample, elements of the Nye-tensor can be determined. With the help of Nye’s tensor, dislocation density can be calculated for the certain sample. Since the measures were carried out with scanning electronmicroscope (SEM), just superficial orientations can be measured. Hence the Nye-tensor is an incomplete matrix, with five elements. Because of the absence of the other four elements just a quasi-dislocation density can be obtained. The algorithm of the calculation was programmed on the language C#.

Abstract: The online exam system is developed by C# language tool, .NET technology and SQL Server 2005 database technology in this paper. And the main function of the system, design idea and the implementation process was expounded also. The randomly generated test and automatic scoring function can be supported by this system. After using test, the performance of this system was stable ,and the function was complete. The paperless and standardized examination was achieved truly.

Abstract: Aiming at the problem that there are many .NET based software need to access COM based OPC servers. This article developed an OPC client for .NET based advanced control software. Firstly, this article introduces the structural characteristics of OPC, then describes the whole process to develop this client software, and finally shows the experiments result that the client could access data with an OPC server stabilized. This client could be a good solution to solve the communication problem between .NET and COM platforms.

Abstract: The management of user permissions is one of the basic and important functions to ensure the safety of a management information system. Firstly, this paper analyzes the shortcomings of the tow kinds of access-control methods generally used; then brings forward an algorithm of Traversal system menu items and stored the items in database; finally, realized the algorithm in C# with an application. By using the algorithm of traversal menu items, user permissions of a system can be controlled easily and dynamically.

Abstract: Microsoft China had announced that it would end on a Windows XP system support and maintenance in the April 8, 2014, progress in the new study. NET development environment, further research database development technology is very important. C# in. NET framework most popular development language, compared to other languages, which have simple, convenient, rapid development, etc.^[1]. Based on data access technology under. NET Framework, which provides a number of features to improve the operation of data. This article also describes in the latest. NET Framework, a new language inheritance query technology LINQ.

Abstract: Face the reality application in the "information island" problem, based on the analysis of the data exchange between heterogeneous database conflict, on the basis of this paper proposes a data exchange model in XML as middle format. Make full use of the XML is easy to extend, good interactivity and semantic is strong, can be formatted, easy processing, has nothing to do with the platform, and other features and advantages, and USES the c # language and XML and related technologies of the model carried on the detailed design and implementation of the main modules, and each function module in the model are relatively independent and extensible, strong commonality.

Abstract: In the process of the traffic accidents confirmation, the identification of vehicle speed when accident occurred is often an important basis for accident confirmation. The paper firstly discusses the models of mechanics and solving method for the vehicle front face, rear end, sides face ,slanted side collision based on the theory of collision mechanics ,it describes how to identify the vehicle rate and collision angle based on the model simplification, the theoretical analysis for dealing with the complicated accidents. The common and formulas are studied based on the classical collision mechanics method. The application range, parameters involved in selection and influence of the formulas are analyzed in detail. Finally the program based on C# is developed according to the identified calculation process for vehicle speed of traffic accident. The vehicle speed is obtained by selecting the collision type, entering the relevant accident pattern, inputting the parameters and clicking the command button .The application can store, modify and display results conveniently , improve efficiency on vehicle speed identification effectively and reduce the processing cycle of traffic accident availably.

Abstract: Body static stiffness is an important index to evaluate the vehicle performance, and test is a main evaluation method for the static stiffness. Accordance with the existed problem of static stiffness measurement, we developed a bending and torsion stiffness measurement system. The system includes loading device, test bench, displacement sensor and fixture, data-acquisition system and software. The software communicates with slave computer (PLC) through serial interface to make data process and store. It also could do stiffness analysis according to relative methods. Practical application shows that the system could measure the static stiffness accurately.

Abstract: In this paper, the type selection of resistance spot welding guns and 3D part drawings library are developed based on the C# programming software and Solidworks environment. It is called rswg-swc software system. The selection method of resistance spot welding guns is analyzed, 3D graphic library about the general parts and series parts of welding gun is established .Utilizing the user interface, input the necessary parameters to choose corresponding product model, product assembly drawings and part drawing are created in Solidworks.

Abstract: Most of mining and metallurgy industries are the mining, metallurgical enterprises that are located in mountainous or remote areas and far away from the city, so the information resources are isolated. Especially for the information dynamic of the mining, the characteristic information resources of industry are more difficult to find. This system can realize the information integration of mining and metallurgy industry, provide the electronic trading and literature service, and realize the visualization of the ore dressing process flow by using virtual technology. The program was proceed using C# in this system, and the develop was proceed in the .NET platform, and the SQL SERVER2008 was as background database.
