with the rapid development of national economy, the construction of our country and technical personnel requirements also produced corresponding changes, the demand for interdisciplinary talents gradually increased to the higher education has put forward higher requirements. The direction of the civil engineering course reform is changed to "large civil specialty” as the basic starting point, combine with the reform of talented person training mode, adjust the students' knowledge structure. The task of introduction to civil engineering is to cultivate the students' awareness of civil engineering major, make low grade students understand the civil engineering involved in the field of the content, methods, achievements and development situation about civil engineering comprehensive from the visual angle of safe academics, social and security technology, economy and management unity. The new understanding of civil engineering specialty, enhances the student to study the interest of engineering knowledge, broaden their knowledge. According to the positioning of the course, in the teaching process optimization of teaching materials, reasonable allocation of hours, adopt the suitable way of teaching organization teaching, and achieve good teaching results

The water conservancy hydroelectric construction engineering major is establishing an operate in the reform in education and the course, should develop craft advantage, the tapping has the development scheme of the talented person of oneself special feature and quickly takes occupation capability as the course system of nucleus to construct and reform to practice teaching system, intensifies a student to practice to begin capability development and arouses a completely developing of the reform in education; Set up to practice the teaching mass guarantee system, intensify the construction of solid Xun matrix, the reform fulfillment teaching investigates a method, values to produce to learn wedge bonding and speeds the construction of high character teacher's troops. The teaching plans the reform of teaching mode talented person the key of development mode reform at, come out an and profession close correlation, foster a deluxe application person just new road son

A new catalyst with two active constituents interacting with activated carbon was prepared. As a model reaction for coal liquefaction, the hydrocracking of di(1-naphthyl)methane (DNM) was investigated under different reaction conditions over the catalyst. The results show that the catalyst converts DNM hydrocraking into 1-methylnaphthalene and naphthalene with high selectively, without any hydrogenation product. Kinetic analysis indicates that DNM hydrocracking in the temperature range of 170-300 °C could be considered as a first order reaction. The activation energy E and pre-exponential factor A for DNM hydrocracking for different reaction times were calculated.

There are many kinds of Ecological-type revetment, including types of Natural vegetation, Masonry, Eco-Concrete and so on. What is more, the engineering characteristics, economic cost, suitable condition of application are all different. Therefore we should choose appropriate types of ecological-type revetment in the construction of river channel for small cities and towns. This article includes the overview of the progress of ecological-type revetment rectification measures, the types and characteristics of ecological-type revetment. Selection principles of economics, security, aesthetics as well as the consideration of the idea of harmonious coexistence between man and water in ecological-type revetment construction are proposed.

In this paper, based on the theoretical analysis and reasonable simplification, one-dimensional mathematical model is presented for the counter-current oxidation of ventilation air methane. The process of counter-current oxidation reaction is simulated by applying the computational fluid dynamics (CFD) software (Fluent), and the effect of the dominating working parameters (such as flow velocity and equivalence ratio and half cycle) are discussed on the temperature and rate of reaction within the counter-current oxidation reaction. The distribution of the temperature field and the reaction rate are simulated when half cycle is 30s, the equivalence ratio is 0.2 and the velocity 0.06 m/s, 0.1m/s and 0.2 m/s. The combustion characteristics are summarized for the device of counter-current oxidation reaction, and the effects of working parameters are analyzed on the burning characteristics. It is so important to increase the combustion efficiency and energy utilization.

The course of hydraulic engineering construction is a major course of hydraulic engineering, which covers the characteristics and teaching aims in higher vocational colleges. It analyses the teaching situation and problems in course teaching. This essay has deep thoughts of this course and makes some suggestions for reference.
