This paper presents an advanced low-cost temperature control system. The system takes the highest performance-cost ratio as its aim. It uses the low-cost 8-bit MCS-51 MCU and integrated temperature sensor to achieve the on-site control. A lower cost remote host computer can be used in this system. In the case of a relatively larger application, it can be expanded to a control system of master-slave distribution and utilize the computing and storage resources of the microcontroller. It realizes a wider range of temperature adjustment, and then put the state of the system into a database of the microcontroller to be ascertained later.

The sensor materials are the foundation of sensor technology. The development andapplication of new materials promoted the progress of the new sensors. The new application of conductive composite materials, composite nanomaterial, and carbon nanotubes materials were presented briefly in this paper on the multi-functions flexible tactile sensor, electrochemical biosensor, and semiconductor gas sensor. Sensor is one of the lead parts in measuring system that convert the input variables into measurable signal. It is an important part of the sensor system and a window responsible for information collection in the sensor system. Owing to the development of modern information technology andcomputer processing technology, the sensor technology research has improved greatly. Sensors play a more and more important role in modern industrial fields. Meanwhile, they also become a key component and essential lead unit in information collection system, automatic control system. Because of the rapid development of super large scale integrated circuit, the modern computer technology and communication technology's demand in accuracy, reliability, sensor response speed and obtain information is higher and higher, its low cost and easy to use also need to improve. The sensor material is the important foundation of the sensor technology and the development of new materials andapplication promote the development of the various kinds of new sensors.

The specification of Trusted Computing requires that all the components running on trusted computing platform should be trusted, which has seriously hampered the application of trusted computing platform. This paper presents a flexible trusted terminal model of tolerance non-trusted components. Compared with the existing trusted computing platform, the model allows the existence of non-trusted components, in the mean time it can also guarantee the predictable and controllable of security result. The model is divided into trusted domain and non-trusted domain of tolerance non-trusted components. Based on the noninterference theory of information flow and the noninterference theory of interdomain, the paper presents the tolerance mechanism of non-trusted components and derives the sufficient condition that the trusted terminal should meet. On this basis, the specific physical model design is given and the model is proved to be a trusted terminal model.

The whole world is undergoing great changes and twenty first century is an internationalized and high-tech era which is transforming from industrialized society to informatization ones. With the rapid development of science and technology, the upsurge of the new and interdisciplinary course, along with the merge and combination of literal arts and scientific arts, all these factors have contributed to the grim challenge that we faced during the process of cultivating foreign language talents. In order to face the challenge, the foreign major must gear to the demands of the system of market economy and cultivate the compound talents. Therefore, it is essential to improve the teaching devices and adopt advanced teaching facilities. The development of science and technology have made it possible for us make good use of teaching facilities and provide abundant resources. Multimedia technology is becoming more and more popular with college students, nowadays, it plays an important role in enhancing the teaching efficiency.
