The purpose is to increase the numbers of the water-based radicals, ionize the water molecule and improve the desulfuration efficiency of pulsed corona reactor. The water ions were determined by four stages molecular beam mass spectrometer and diagnose the water-based radicals by emission spectrograph. A conclusion on formation of ions and radicals with DC corona discharges can be drawn.展开更多

The carbonate gravity deposits are well developed there, particularly in the Yangtze platform adjacent areas. This paper mainly d eals with declivity fan characters of the Chefu age in Fenghuang adjacent areas, western Hunan Province. According to their distribution and thickness, three ma in declivity fans have been divided in the study areas, namely, Dama (∈c dsf), Machong (∈c msf) and Huangheyuan (∈c hsf) declivity fans. Each fan's charac ters are described in detail in this paper. Based on their distribution range, s cale and fossiliferous layers, two peak periods (fair developmental period) are distinguished: (1) Linguagnostus reconditus Zone (time), and (2) Glyptagno stus reticulatus Zone (time). They were characterized by huge thick limestone breccia layers (single layer 3-4 m thick) and closely spaced spread. Besides, th ere are also two developmental periods: (1) Lejopyge laevigata Proagnostus b ulbus Zone (time), and (2) Agnostus inexpectans Proceratopyge protracta Z one (time) to Erixanium Zone (time) to Corynexochus plumula Sinoprocerato pyge cf. kiangshanensis Zone (time), while Glyptagnostus stolidotus Zo ne (time) was an interstitial period (without or rare limestone breccias). All t hese features may verify the relative movement of the earth crust and paleoclima te variety of the Chefu age in the study areas.展开更多

They are looked upon as China’s national treasure. Covering a total area of 12,611 hectares, the nature reserve is also home to other wildlife species, such as antelopes, golden monkeys, and leopards.A patrol of 11 members, formed 15 years ago, works to protect animals living on the reserve, and their natural environment. Each month it spends 3 to 5 days on three inspections. In the 1980s the patrol rescued and treated an injured giant panda they found on the mountain.展开更多

The classic centralized paradigm, adopted by SNMP, which was once appropriate in theprevenient phrase, has posed problems with the explosive expansion of networks, as well as othercentralized models. Mobile Agent (MA), owing to its capability of implementing a distributed system,represents a challenging approach to provide network management with high performance. In thispaper we analyze the network management structure model based on MA at first, and then we putforward a reference scenario based on MA and compare it with the traditional model. We also describea prototype implementation based on our mobile agent system named MAS. Finally, we do someexperiments to verify the performance of our framework prototype.展开更多

文摘Positive DC corona discharge is formed with needle-plate electrode configuration, in which the water vapor is ejected though the needle points. The purpose is to increase the numbers of the water-based radicals, ionize the water molecule and improve the desulfuration efficiency of pulsed corona reactor.
