The functional and logical structures of EDSTRC as well as its sub-systems are mainly designed, and its development and application environment are simply introduced. EDSTRC is consisted of eight main parts, i.e. data base (DB), knowledge base (KB), model base (MB), approach base (AB), graph base (GB), result base (RB), man-compute system (MCS), and problem-solved system (PSS). Through application of practical examples, it is proved that the EDSTRC’s prototype design is correct, its man-computer interface is amicable, and its applicable prospect is wider.展开更多

To some extent, the application of electronic engineering automation can bring about a revolution in production, reduce the input of human cost, liberate peoples hands, and help people pay more attention to the research of high-tech electronic engineering automation, and how to integrate with production and daily life to make the most of the advantages of electronic engineering automation. The article is to explore the changes in peoples lives brought about by the modernization of electronic engineering automation, based on the study of electronic equipment in daily use, how to use communication, navigation and infrared technology in electronic engineering to change peoples life and mode of production, and how to better use electronic engineering automation research.展开更多

Nevertheless, one major issue is the curtailment of costs incurred in producing synthesis gas from natural gas, which account for approximately 60% of the costs used in producing liquid fuels. While there are three main routes to convert natural gas to syngas: steam reforming (SMR), partial Oxidation (POX) and auto-thermal reforming (ATR). Significant new developments and improvements in these technologies, established innovative processes to minimize greenhouse gases emission, minimize energy consumption, enhance syngas processes, adjust the desired H<sub>2</sub>/CO ratio and change the baseline economics. This article reviews the state of the art for the reforming of natural gas to synthesis gas taking into consideration all the new innovations in both processes and catalysis.展开更多
