Abstract: The virtual reality technology is a three-dimensional virtual environment composed by computer hardware, software and various of sensors. It creates an unprecedented wealth of content and more fantastic teaching environment which reflects strong advantage in experiment and practice. In accordance with the needs of experiment teaching, multi-level interrupt virtual experiment environment is studied combining with the characteristics of its principle. The experiment environment is based on Tec-xp test box designed and developed by Tsinghua University computer factory. Microsoft Visual C++6.0 language is adopted for software platform development. Seen from the system needs analysis, object-oriented simulation method is adopted for modeling in this experiment environment. Meanwhile combining with computer system features and the characteristics of Computer Organization Principle teaching, the basic theory and methods of discrete event system simulation are used, which make the operation of virtual environment the same as on real device.

Abstract: Retracted paper: Object-oriented is an important feature of operating system, and it is not exclusive to its micro-kernel architecture but promoting it. Object-oriented technology embodies design and implementation, which makes idea and realization possible. Due to the openness of transmission medium, LAN communication requests higher and better steganography-keeping performance. Through the features of LAN network security, the LAN security framework and hierarchical network security technology are proposed. Based on the basic principles and common methods of steganography information and the commonly used methods, combined with steganography capacity and the distortion changes of statistical properties, the improved LSB steganography writing with anti-steganography is given. In conclusion, the method can write different amount of data in different regions.
