With the development of the computer technology, the monitoring and controlling system is getting more and more important in central heating. Taking the central heating of Caofeidian for example, this paper introduces the structure, feature and function of monitoring and controlling system in central heating. The network constitute of remote monitoring controlling system of the central heating described in detail and the realization of communication. The result of operation indicates that the system is stable, and offers high regulation accuracy and is easily operated, which meets the requirements of long-term stable operation of remote monitoring. © 2011 IEEE.

This paper reports result of a study conducted to evaluate the aging properties of isobutyl triethoxysilane coating used in marine concrete. The silicone coating was brushed to the surface of mortar specimens and the aging properties of the silicone coating were investigated by thermal aging and ultraviolet (UV) aging. The water absorption of the mortar specimens applied with the silicone coating increases with the extension of the aging time. And the higher aging temperature, the bigger the water absorption. Because of the combined effect of light and heat, water absorption of specimens after UV aging at 60 °C is larger than that after thermal aging in the same temperature. In addition, noticeable variation in aging properties of the same silicone coating by different manufacturers is noted. © (2012) Trans Tech Publications. Source

Dissolution model of cement clinker minerals was set up based on simulation theory of geochemical reaction equilibrium, PHREEQC simulation software provided by United States Geological Survey (USGS) was employed to investigate effects of various ions, pH, temperature, ionic strength on dissolution of minerals. The results show that the temperature, pH, ionic strength, common-ion effect and varied ions have significant effects on dissolution equilibrium of the minerals. Specifically, Na+, Cl- and K+ present little effects on clinker minerals, however, Mg2+, SO4 2- and Ca2+ have significant effects on dissolution equilibrium of the minerals. Dissolution of C3S and C2S accelerated with increasing Na+. Gypsum contributes to the increase of SI of clinker minerals except for C3A. Equilibrium constant increases and SI decreases with increasing temperature. Equilibrium constant and SI decrease with increasing pH. Source

The actual driving data of Dalian city is collected by GPS devices and divided into kinematics sequences. After characteristic parameters of the kinematics sequences are calculated, this paper makes component analysis and cluster analysis to extract the representative driving data. The driving cycle of Dalian is constructed based on the analysis result of the representative driving data. The driving cycle of Dalian is compared with the driving cycles of Zhuzhou city and Chinese typical city. Comparison result shows that Dalian driving cycle is crowded. © 2015 SERSC. Source
