International audience ; With the development of informationization in village in Shandong Province, it needs a system to create a webpage for each village on which the villager can look for their interested information and post message. The article puts forward the frame design of the system from its function, hardware, performance and items etc aspects. The system provides the platform for "information to countryside" so as to make the rural government affairs public, reduce the contradiction between the party and the masses and between the cadres and masses and construct the harmonious new village.

Nitrocellulose (NC) is widely used in both military and civilian fields. Because of its high chemical sensitivity and low decomposition temperature, NC is prone to spontaneous combustion. Due to the dangerous properties of NC, it is often dissolved in other organic solvents, then stored and transported in the form of a solution. Therefore, this paper took NC solutions (NC-S) with different concentrations as research objects. Under different atmospheric conditions, a series of thermal analysis experiments and different reaction kinetic methods investigated the influence of solution concentration and oxygen concentration on NC-S's thermal stability. The variation rules of NC-S's thermodynamic parameters with solution and oxygen concentrations were explored. On this basis, the spontaneous combustion characteristics of NC-S under actual industrial conditions were summarized to put forward the theoretical guidance for the spontaneous combustion treatment together with the safety in production, transportation, and storage.
