Tidal disruption events(TDEs)of stars by supermassive black holes(SMBHs)can be used to probe the dormant SMBHs in distant galaxies.The long-term light curve
茂金属催化剂具有单一活性中心、较高的活性和优良的共聚性能,是近二十年来国内外高分子领域的研究热点。但是,均相茂金属催化剂制备的聚乙烯(PE)形态(颗粒形状和大小)难以控制
DAWOO PARK Dynamics of Globular cluster(GC)is dominated by behaviors of high mass components such as neutron stars or black holes(BHs).In early phase of GC
Recent studies suggest a statistical anti-correlation between the X-ray variability amplitude and black hole masses in active galactic nuclei(AGN).As the es
植物耐盐是由多基因控制的,其相关的基因涉及到很多方面,比如细胞防御、代谢、离子平衡和转运等等,所有的这些基因构成了一个复杂的调控系统。因此,对盐胁迫应答基因进行研究有助于我们更好地了解植物耐盐机制,并运用于农业生产之中。世界上分布最广、种植面积最大的粮食作物—小麦,是一类非常重要的研究对象。耐盐、旱小麦品种山融3号(SR3)是小麦品种济南177 (Triticum aestivum2n=42)与其
When modeling the dynamics of galaxies,several numerical techniques can be applied.Most useful are the direct N-body codes,tree codes and particle-mesh code
芒是禾本科植物小花外稃上的突出物,是禾本科植物的外稃顶端由中肋延伸而成的结构。芒作为野生稻中普遍存在的一个结构,可以帮助种子散布,同时防止鸟兽啄食。但是,在长期的人
A standard correlation between the radio and X-ray luminosity,i.e.LR∝L~0.5-0.7Xwas found in the low/hard spectral state of black hole X-ray binaries.Howeve
Stars are tidally disrupted and accreted when they approach supermassive black holes(SMBHs)closely,producing a flare of electromagnetic radiation.The majori
