Large explosive volcanic eruptions generate extensive regional tephra deposits that provide favorable conditions for identifying the source of volcanoes, comparing the sedimentary strata of a region and determining their ages. The tephra layer, referred to as B- Tm, generated by the Millennium eruption of Chang- baishan volcano, is widely distributed in Northeast China, Japan, D.P.R. Korea, and the nearby coastal area of Russia. It forms part of the widespread northeast Asian strata and is significant for establishing an isochronal stratigraphic framework. However, research on the temporal characterization and stratigraphic correlation of associated strata using this tephra layer is mainly concentrated in and near Japan. In northeastern China, this tephra layer is seldom seen and its application in stratigraphic correlations is even rarer. More importantly, the determination of accurate ages for both distal and proximal tephras has been debated, leading to controversy in discussions of its environmental impacts. Stratigraphic records from both distal and proximal Changbaishan ash show that this eruption generally occurred between 1,012 and 1,004 cal yr BP. Geochemical comparison between Changbaishan ash and the Quaternary widespread ash around Japan illustrates that Changbaishan ash is a continuous composition from rhyolitic to trachytic and its ratio of FeOT to CaO is usually greater than 4, which can be used as a distinguishing identifier among worldwide contemporary eruptions.

The Longmenshan Structural Belt on the eastern edge of the Tibetan Plateau experienced the impactful Mw 7.9 2008 Wenchuan earthquake， causing a 350 km surface rupture. Traditional models attribute this to the Beichuan and Pengguan faults， but our research reveals a complex fault system at the northern end， with inconsistencies in surface rupture， aftershock distribution， and focal mechanisms. We integrates shallow geology， active source seismic reflection， and magnetotelluric profiling to establish a deep structural model for the northern end of the Longmenshan Structural Belt. This area exhibits dominant reverse thrust nappe tectonics， and analyzing the tectonic evolution history provides insights into deformation propagation from the orogenic belt toward the Sichuan Basin. Focal mechanism analysis and relocated aftershock data reveals two distinct types of seismogenic structures in the northern end of the Longmenshan Structural Belt. In the middle to northern segments， the reverse fault type is attributed to reactivated pre-existing faults. Conversely， at the northern end， the strike-slip fault type originates from high-angle co-seismic rupture cutting through pre-existing reverse faults. This study enhances our understanding of fault complexity and seismic mechanisms in the northeastern Longmenshan Structural Belt， providing new insights into regional tectonics.

管网的微观水力模型通常将所有水量依据管段的长度分配到各个节点.通过研究这种供水管网传统水力模型,针对该模型忽略节点流量类别直接将总漏失量平均分配到管网中的问题,将传统水力模型中的节点流量分为用户用水量和漏失水量,并运用改进的一致漏损模型将管段的漏失量按管段长度分配,构建漏失水量与压力之间的关系式,建立压力驱动节点的水力模型(PDD).模型形成后,根据实际测压点数据对模型进行校核,以达到模型校核标准.将该模型应用于Y市实际管网,根据Y市实际管网数据得到的平均漏失率,建立计算供水量与实际供水量的适应度函数,计算供水管网模型中的漏失系数,最终实现基于压力驱动节点流量的供水管网漏失模拟.结果表明,校核后的PDD模型与实际供水管网运行压力情况吻合良好,可以进行管网漏失控制研究及评估.

Nanocrystalline Mg2Ni-type alloys with nominal compositions of Mg20Ni10 – xCux (x = 0, 1, 2, 3, 4) were synthesized by rapid quenching technique. The microstructures of the as-cast and quenched alloys were characterized by XRD, SEM and HRTEM. The hydrogen absorption and desorption kinetics of the alloys were measured using an automatically controlled Sieverts apparatus. The electrochemical hydrogen storage performances were tested by an automatic galvanostatic system. The results show that all the as-quenched alloys hold a typical nanocrystalline structure, and the rapid quenching does not change the major phase Mg2Ni. The hydrogen absorption and desorption capacities of the alloys significantly increase with rising quenching rate. Additionally, the rapid quenching significantly improves the electrochemical hydrogen storage capacity of the alloys, but it slightly impairs the cycle stability of the alloys.
