摘要:
In this paper, the logistic regression model is applied to analyze the influence of the factors affecting the Basics of Computer Application and College English B exam results. To model the logistic regression by using the two course exam results as a target variable, the analysis results show that: grade, specialty and learning center have great impact on the Basics of Computer Application, while the grade, learning center, age, specialty and gender are all have very important implications on the College English B exam results..

摘要:
Recently, with development of computer technology, the application field of near-infrared image processing becomes much wider. In this paper the technical characteristic and development of modern NIR imaging and NIR spectroscopy analysis were introduced. It is concluded application and studying of the NIR imaging processing technique in the agricultural engineering in recent years, base on the application principle and developing characteristic of near-infrared image. The NIR imaging would be very useful in the nondestructive external and internal quality inspecting of agricultural products. It is important to detect stored-grain insects by the application of near-infrared spectroscopy. Computer vision detection base on the NIR imaging would be help to manage food logistics. Application of NIR imaging promoted quality management of agricultural products. In the further application research fields of NIR image in the agricultural engineering, Some advices and prospect were put forward.

摘要:
Talent Cultivation is the precondition for competition and development in a knowledge society. As an important means of talent cultivation, Web-based Network teaching or distance education not only has brought us an opportunity but also has raised a challenge to us. It is a vital issue related to cultural quality of the population as well as the development of the society that how we educators can cultivate more and more high quality talents for the society. This paper discusses relation of Web-based Education Technology and traditional education and applications of the web-based education technology for the basic education in rural areas, intends to put forward some problems and advices.

摘要:
Organic contaminants are harmful to body health, and are usually contained in waste water, so it is necessary to determine and monitor them. The demand for real-time analysis and online examination of organic contaminants in water has presented a challenge to analytical and physical chemist. Raman Spectroscopy is a molecular vibrational spectroscopic technique, and Raman effect is caused by interactions of molecule and photon and shows the information in molecules. Because the Raman spectra of different molecules are much more distinct, they provides characteristic of the molecule. Especially, Raman spectra of the solutes are unaffected by the water, therefore the weak scattering of water makes the technique well suited to analyzing aqueous contaminants. The paper firstly introduced Raman spectroscopy, and then analyzed and assigned the Raman spectra of five kinds of organic contaminants and their mixture. The results showed that Raman spectroscopy is a powerful technique for analyzing aqueous solutions of organic contaminants.
