Abstract: Soil Mechanics is a very important fundamental course for the students majoring in Civil Engineering and Water Conservancy and Hydropower, and a bridge connecting common fundamental courses and specialized courses. With the enlarging utilization of multimedia technology in the teaching process of the course of Civil Engineering, the teaching effect and efficiency have got increased. However, the multimedia teaching method itself has certain faults, and can only meet the needs of the workers in the teaching field through constant reform and innovation.

Abstract: A Questionnaire Investigation of CAI on College Physics was carried out in 23 higher education institutes of Henan Province and the findings were compared with the teaching method in a traditional way. It has been proved that physics teaching at college assisted by multimedia courseware has some advantages over that in a traditional way since the former provided a larger output of knowledge, a higher level of knowledge acquisition compared with the physics teaching in a traditional way. And it is also found that text courseware alone might not achieve better results in the physics teaching at colleges.

Abstract: The soil mechanic course acts as a professional basic course of civil engineering. In recent years, we have made a better teaching effect by enriching teaching contents constantly and improving the teaching methods and means, but under the new situation there still exists certain shortage and weakness that need to strengthen. Based on the experience in teaching the author has putted forward the main problems existing in the teaching of soil mechanics course. What’s more, the specific suggestions on teaching reformation and practice have been suggested.

Abstract: Because of its advantages of small size, light weight, powerful etc., the single chip microcomputer(sometimes called “SCM”, ”microcontroller”, or ”MCU”) has a very wide range of applications in information appliances, instruments and meter, industrial control, medical apparatus and communication systems. The serial port is one of the most important resources in the microcontroller and has a very important role in the embedded application system. Some application skills of the serial port in experimental teaching and development of embedded products are discussed in this paper, such as the serial port application in program debugging during experiment teaching, multiple serial port expansion technology and implementation method of USB interface during development of embedded application system.

Abstract: A kind of cooperative lesson preparation mode for electronic experimental teaching was put forward in this paper aimed at solving some common issues in electronic experimental teaching. For example, electronic experimental teaching has lagged behind the development of electronic technology, teachers have been exposed to great pressure and therefore perform poor lesson preparation, teaching and research levels of full-time experimental teachers have been unsuitable for new situations, etc. Correspondingly, a cooperative lesson preparation mode of electronic experimental teaching was proposed. The mode involved a series of steps and forms such as clarifying objectives, exerting individuality, sharing resources, authenticating each other, evaluating and reflecting, etc. Teachers were inspired and exerted in passion and potential fully by grasping and using some rules and functions in psychology, efficiency and non-cognitive characters. During practice of two semesters, teaching and research atmosphere of the circuit center has become increasingly thick and teaching quality has improved significantly.

Abstract: The glycoprotein H(gH) gene homologue of pseudorabies virus wild strain SL(PRV-SL) was cloned by degenerate polymerase chain reaction (PCR) from PRV infected vero cells. Bioinformatics analysis was performed to predict the characteristics of gH, the results indicated that gH gene encoded a polypeptide, molecular mass of 71.95kda and comprising 687 amino acids. The protein had one signal peptide between 1 and 24AA, one transmembrane region 645-667AA, 27 antigenic determinants and the hydrophobicity between -2.117 and 3.178. The prediction of secondary structure showed that gH had consisted highly of alpha helix(Hh) and random coil(Cc). The phylogenetic tree showed that PRV-SL was similar to others of the Alphaherpesvirinae, and that gH had higher conservative in Alphaherpesvirinae. Cloning and analysis of gH gene laid foundation to further research and exploitation.

Abstract: On the present situation of the metalworking practice, gives some suggestions to the reform of teaching mode and optimize the content, in order to make the metalworking practice play a bigger role for students to improve practical ability, enrich their own knowledge, study subsequent courses and join in work, etc.

Abstract: Instead of traditional mechanical tape , A new type digital broadcast system on passenger train is introduced, It adopt the microcontroller technology and MP3 decoder method ,complete the whole function of broadcast system. The design of hardware and software is described. Its application in the broadcast system is also introduced. The system has been produced on a small scale. Its implementation in a passenger train is successful and effective.

Abstract: The network curriculum is an important component of the omni-directional course resource construction. The key of the omni-directional course resource construction is how to combining the network curriculum and the traditional classroom teaching together efficiently. This paper puts forward the corresponding design principles of building a collaborative network curriculum based on the blended learning technology. The corresponding design principles includes emphasizing the teaching design strategy based on task-driven of the network curriculum tent presentation and emphasizing the learning situation strategy base on project- driven of the curriculum implementation strategies. With a series of security strategy, it realizes the powerful and practical cooperative network curriculum..

Abstract: This article first introduce the importance of C++ language in the course of object-oriented, and the teaching mode before. Aim at the problems in the past mode of C++ teaching, the author analyses the problems in essence. And then, the author proposes a new method that is combination of MFC in C++ language teaching. Because of the MFC's inherent characteristics and the MFC are packaged by C++ language grammar. The instruction overcome many problems that exists in the last C++ language teaching, such as dull, lacks vividness and the lack of achievement. At the same time, the author has successfully applied for this instruction mode in his own teaching process.
