New Develoopment of the Basic Theory of Extenics

In this paper,the new development of three basic theories of Extenics,incluing basic-element theory,extension set theory and extension logic theory ,has been introduced.And the new theoretical frame of Extenics has also been set forth.     

Research on Tracing Evaluation System in Virtual Enterprise Based on Neural Network

The tracing evaluation index system was designed to be used in virtual enterprise and established neural network trace evaluation model. As a result, it was more simple and nicer than the traditional method, so it had wider application foreground.     

Pilot Study on Nanofiltration Combined with Ozonation and GAC for Advanced Drinking Water Treatment

IntroductionThe conventional process for surface water treatment,which consists of flocculation, sedimentation and filtrationcurrently, had been applied inproducingdrinkingwater formany years. Although this process can remove turbidityand bacteria in surface water effectively, only about from20% to 30% of natural organic matter ( NOM) can beeliminated. When the purified water is disinfected bychlorination, these NOMs may react with chlorine. As aresult some dis…

Earthquake Resistant Engineering and Application of Seismic Zonation Map of China

China is a country with high seismieity. It is very important for industry and structure to fortify against earthquakes. In this paper the outline of seismicity in China, the criteria for fortification against earthquakes and the contents of seismic zonation map of China are described. The contents of seismic safety evaluation for major construction projects, such as large dams, large bridges, long distance pipe lines for transporting oil and natural gas, nuclear plants, petrochemical enterprises and so on, are presented. Some geological disasters caused by destructive earthquake, such as earthquake-caused collapse and landslide, liquefaction of saturated soll and earthquake fault and so on, are also presented. Preventive countermeasures for these disasters are discussed.
