VLBI is a radio observation means who has the highest precision currently.To solve the problem of over-high requirement to processing speed of hardware,a wideband VLBI digital baseband converter based on parallel down-conversion is designed,combining parallel processing with polyphase filtering,which can greatly reduce the requirement to processing speed,relieve the pressure of hardware,and is helped to solve the bottleneck problem of digital signal processing.

Nitrification,a greenhouse gas (N2O) producer and hypoxia contributor,has been widely concerned in coastal seas especially after the dramatic increase in anthropogenic nitrogen input since industriali
Studies of the fate of carbon in marginal seas are vitally important to understanding of the ocean carbon cycle.As a part of the CHOICE-C project,an integrated study of carbon dynamics in the marginal
An increase in nutrients in the continental shelf is always thought to be associated to coastal upwelling,but it may not necessarily be the case in the continental shelf near the Pearl River estuary.T
奇古菌(Thaumarchaeota)是海水中一类丰富而活跃的微生物类群,参与氨氧化和不依赖光能的固碳等生物地球化学作用.然而,尽管海洋沉积物构成了地球表面的大部分,沉积物中奇古菌生态功能的研究却很少有开展.
We examined the degree of silicate recycling in two contrasting environmental settings in the northern South China Sea,one in a coastal upwelling system and the other in the oligotrophic basin area at
