The adsorption behavior of NO over the catalysts is a key point in the investigating of NO reduction,such as selective catalytic reduction(SCR) and selective catalytic oxidation(SCO). As the activated carbon(AC) is the most common adsorbent and catalyst carrier,so the raw coconut shell AC was chose as the NO adsorbent in this *** adsorption behavior of NO at temperatures ranging from 298-343 K and the thermodynamics of adsorption had been *** the adsorption equilibrium data for NO were fitted to Freundlich,Dubinin-Radushkevich(D-R) and Temkin isothermal *** results showed that the Freundlich equation is more suitable to describe the process of NO adsorption over coconut shell *** heat of adsorption was determined by the Clausius-Clapeyron *** maximum value of heat of adsorption is 17.67 kJ/mol, which indicated that the adsorption of NO by AC may be a dominant of physical adsorption. Based on above analysis,series of the modified AC adsorbents,which loaded Ba-Mn and Ba-Mn-Ce,were prepared for the NO ***,the influence of different mole ratio of metals,calcination temperature and calcination time on the NO adsorption behavior over the modified AC had also been *** the adsorption equilibrium data for NO were also fitted to the three isothermal *** addition,we contrasted NO adsorption behavior on the Ba-Mn-Ce/AC,Ba-Mn/AC and raw coconut shell AC adsorbents.

The sediment flux data, measured from a dry-hot valley of the Longchuan River, a tributary of the lower Jinsha River, were analyzed with Mann-Kendall test, Seasonal Mann-Kendall test and Sen’s test. In both the upper reaches (Xiaohekou) and the lower reaches (Xiaohuangguayuan), the sediment fluxes showed a significant increase from 1970 to 2001, despite the fact that the water discharge did not change significantly during the period and numerous reservoir constructions which contribute to the trap of sediment. This can be attributed to the intensification of human activities, especially the activities related to land surface disturbances such as deforestation and afforestation, expansion of agriculture land, and road constructions. This increase is more significant in the lower reaches of the river observed at the place of Xiaohuangguayuan due to the dry-hot climate. The profound increase in sediment flux has significant implications for effective management of the sedimentation problems of the on-going Three Gorges Reservoir.

Employ theory of bifurcations of dynamical systems to a system of coupled nonlin-ear equations, the existence of solitary wave solutions, kink wave solutions, anti-kink wave solutions and periodic wave solutions is obtained. Under different parametric conditions, various sufficient conditions to guarantee the existence of the above so-lutions are given. Some exact explicit parametric representations of travelling wave solutions are derived.

With the development of economy and society, the competition between companies is more and more drastic. Enterprise has to change their commercial mode from "product-oriented" to "customer-oriented" due to the cruel actuality. To diesel engine industry, service is very important But, the diesel engines are not sold to the final customer, so there are many question and trouble in their service for customers. In this paper, the status quo and requirement of diesel engine industry are analyzed, a system for the customer service which make using of the Internet, computer and communication technology adequately and realizing the integration with the existing system is conceived, and the paper explain the structure detailed from the overall framework and the function designing sides.
