[Method] The present research studied on daily biogas yield and the accumulated biogas amount through anaerobic digestion of corn straw and sludges from four sources. [Result] The accumulated biogas yields produced from sludges in four sources from high to low were granular sludge, river sediments, concentrated sludge and filtered sludge. The first one proved the highest at 3.73 and 56.29 L/kg VS in daily biogas yield and the accumulated biogas. [Conclusion] The research laid foundation for full utilization of straw, improvement of energy utilization and sustainable development.展开更多
文摘固态氧是唯一已知的元素分子磁体。在大气压下(约10^5Pa),它是一种反铁磁性的绝缘体,而在大约9.6×10^10Pa时变成为超导体和金属(见Desgreniers S,Vohra Y K,Ruoff A.J.Phys.Chem.,1990,94:1117和Shimizu K,Subara K.Nature,1998,393:767).理论预言,氧将在变成超导体之前失去其磁性,但是此前的实验从未直接观察到过这种非磁性状态。法国Laboratoire Leon Brillouin(LIB)实验室的Goncharenko首次观察到这种磁性“崩溃”(见Goncharenko I.Phys.Rev.Lett.,2005,94:205701).
