针对莫莫格自然保护区,选择3个水体,利用三维荧光光谱结合平行因子分析(PARAFAC)探究溶解性有机质(DOM)的组成、光谱特征和来源;采用二维相关光谱结合结构方程模型分析DOM组分变化及其与水质指标的响应关系.结果表明,水体DOM受内源和外源共同作用,腐殖化特征明显,蛋白质组分含量较低.PARAFAC共识别出微生物代谢产物(C1)、类富里酸(C2和C4)、类胡敏酸(C3)和类色氨酸(C5)等5种组分,其中C1组分含量最高(41.37%);DOM来源、组成、转化与保护区内水生动、植物生长环境下的微生物代谢过程紧密相关,采用2D-COS表征沿水流方向DOM组分的变化顺序为:C4→C2→C3→C1→C5,类富里酸(C2和C4)含量的变化幅度大于类色氨酸,类色氨酸的含量相对比较稳定.C1、C5组分与CODMn呈显著正相关,表明其具有同源性,主要来源于藻类生长死亡过程中产生的大量有机物.DOM来源和组成对水环境因子有直接或间接的影响,DOM主要通过腐殖化程度直接影响水质状态,影响权重为46.17%;DOM组分C2和C3间接影响水质状态,影响权重为17.59%.莫莫格自然保护区水体DOM组成与水环境因子响应机制的研究,可为自然保护区水生态保护提供理论依据.

All-safe liquid-state lithium-ion batteries(ASLS-LIBs) is of great interest as they can potentially combine the safety of all-solid-state batteries with the high performance and low manufacturing cost of traditional liquid-state LIBs. However, the practical success of ASLS-LIBs is bottlenecked by the lack of advanced separator technology that can simultaneously realize high performances in puncturing-tolerability,fire-resistance, and importantly, wetting-capability with non-flammable liquid-electrolytes. Here, we propose a concept of inorganic in-situ separator(IISS) by hybrid-sol physical crosslinking directly onto the electrode surface to address the above challenges. Particularly, the hybrid-sol is designed with silica nanoparticles as the building block and poly(vinylidene difluoride) nanoparticles as the crosslinking agent. The critical factors for controlling the IISS microstructures and properties have been systematically investigated. The advantages of the IISS have been confirmed by its fast wetting with various fireresistant liquid-electrolytes, customizable thickness and porous structures, robust interface with planar or three-dimensional(3D)-structured electrodes, and importantly, unexpected self-adaptability against puncturing. Enabled by the above merits, a fire-resistant ASLS-LIB is successfully assembled and demonstrated with stable electrochemical performance. This sol-crosslinked IISS may open an avenue for the studies on the next-generation separator technology, cell assembling, solid electrolyte processing as well as non-flammable secondary batteries.

钢材锈蚀后的力学性能会发生劣化,已有研究主要关注低碳钢锈蚀后的静力拉伸性能。为研究Q345B低合金钢锈蚀后的力学特性,对22组Q345B钢材试件开展了人工加速腐蚀、单调拉伸与循环加载试验,分析了锈蚀对其单调拉伸和滞回性能的影响,并根据试验数据标定与验证了基于Chaboche模型的混合强化参数。结果表明:钢材单拉应力-应变曲线受锈蚀影响明显,各力学指标均随锈蚀率增加呈线性或非线性退化;循环累积损伤与锈蚀耦合作用会进一步加剧钢材变形能力劣化,同时钢材的耗能能力与循环强化作用亦会受到锈蚀影响;基于循环加载试验数据标定的材料混合强化参数,可较好地模拟锈蚀Q345B钢在循环荷载下的滞回性能,为后续在役钢构件及结构的剩余抗震能力分析评估提供支撑。

The 7 ka old Qixiangzhan lava flow(QXZ,tianchi volcano)represents the last eruptive event before the 946 CE,caldera-forming‘Millennium’eruption(ME).Petrographic,whole rock,mineral composition,Sr-Nd isotopic data on QXZ show that:(a)the lava consists of two components,constituted by comenditic obsidian fragments immersed in a continuous,aphanitic component;(b)both components have the same geochemical and isotopic variations of the ME *** QXZ and ME comendites result from fractional crystallization and crustal assimilation *** temperature of the QXZ magma was about 790℃ and the depth of the magma reservoir around 7 km,the same values as estimated for *** had a viscosity of 10^(5.5)-10^(9) Pa s and a velocity of 3-10 km/*** emplacement time was 0.5-1.6yr and the flow rate 0.48-1.50 m^(3)/*** values lie within the range estimated for other rhyolitic flows *** QXZ lava originated through a mixed explosive-effusive activity with the obsidian resulting from the ascent of undercooling,degassing and the fragmentation of magma along the conduit walls,whereas the aphanitic component testifies to the less undercooled and segregated flow at the center of the *** QXZ lava demonstrates the extensive history of the ME magma chamber.
