Abstract: WSN based on IPv6 is a new network integrated IPv6 and WSN. The related technologies of WSN based on IPv6 was researched, and an architecture of WSN based on IPv6 was proposed according to 6LoWPAN protocol in this article. Efficient and stable route protocol is a main focus to ensure network performance. Refer to on-demand routing protocol DSR, a Load-Balancing route protocol for WSN based on IPv6 was designed. An implementation of this protocol was programmed in NS2, and its simulation results were analyzed. The experimental result shows that this protocol could effectively reduce end-to-end delay and routing overhead, improving the network performance.

Abstract: Differential evolution algorithm is a kind of heuristic random search algorithm, and the traditional sample learning is to find a inductive assertion including all positive examples but not all counter-examples in the example space. But this process is endless and cumbersome because of the large number of the samples. The merit of difference evolution algorithm is searching in the community. So this paper using this merit to combine with sample learning then promoting efficiency.

Abstract: Strengthening the agricultural ecological environmental protection and intensifying the source management of food safety is an important and urgent t task in today's social development process. The article elaborates how agricultural ecological environment pollution affects food safety via air pollution, water pollution and soil pollution. According to relevant statistics, the article describes the current situations of Chinese agricultural ecological environment suffering from fertilizer pollution, pesticide contamination and heavy metals pollution. To solve the problems Chinese government are facing in agricultural ecological environmental pollution prevention and control, the article introduces countermeasures on prevention and control of Chinese agricultural ecological environment pollution to ensure food safety.

Abstract: A fifth order WENO-Boltzmann method for solving the one dimension conservation Euler equation was developed. A generalized lattice Boltzmann distribution function was defined, which could be calculated by the WENO difference schemes. Then the solving of the one dimension conservation Euler equation became the solving of the generalized lattice Boltzmann distribution function by the WENO difference schemes. The method kept the benefits of the WENO method such as the high precision and high resolution, and provided a new way to construct the lattice Boltzmann models for solving the Euler equation.

Abstract: Guizhou province has rich bio-resource and needs a mass of talents to develop it. Therefore, bio-resource-major in Guizhou province should be to train bio-resource-development talents as teaching goal. But existing bio-resource course system in our college can not be able to fulfil the teaching goal, for which the course system need to reform. To adapt to requirement of the course system reformation, new course system of bio-resource-major was discussed and established. The basis on which new course system was set up was knowledge and technique system needed in overall process of bio-resource development.

Abstract: With the development of science and technology, CAE technology plays an increasing important role both to the engineering and technical personnel in engineering and the college students. However, some problems are still in CAE education and training in China at present. The relatively simple content learning and testing can not meet the requirement. Consequently, it is significant to have research on CAE technology education approach and development of models system to improve the effect of the education. In this paper, we have deep research on the CAE practical education approach and then develop the virtual prototype model system which is rich in content; besides, the simulation animation library is also set up. In teaching process, CAI teaching method is mainly used to show the kinematical process of the mechanism, which, when played on computers, the motion process of mechanisms are fleshed out. Multimedia as a means o teaching -aid, can be very effective and helpful to students to understand the difficulties in teaching, especially in mechanical principles teaching. Compared with traditional teaching method, multi-media teaching method has the obvious superiority. In practice, students are in group collaboration, design their own prototype model through calling the parts and accessories in prototype model system, and then complete the kinematical and dynamical analysis on their prototype model. It shows that this teaching method has importance in promoting the quality of education in practice teaching.

Abstract: This paper analyzed the human error in teaching quality control, discussed the prevention methods, and proposed the prevention organization measure, knowledge base and checking measure of human error. The analysis and corresponding measures can be treated as a reference to control the teaching quality for colleges and universities.
