基于ArcGIS,Ucinet等软件,采用旅游时间、位置、文字等数字足迹数据,运用反距离权重插值法、社会网络分析法等方法,构建湖南省旅游流网络结构,分析湖南省旅游流的空间分布与网路结构特征。结果表明:湖南省旅游流的空间分布呈现出西部、西北部核心聚集,东部次核心聚集,中部、南部集中扩散以及少部分地区边缘化扩散的特征;湖南省旅游流网络规模大、整体密度偏低,呈明显的局部集中形态;武陵源、橘子洲、岳麓山、凤凰古城、南岳衡山等节点在湖南省旅游流的发散、集聚、联系、中转等方面发挥了重要作用;交通可达性、空间邻近性等是影响湖南省旅游流网络结构特征的主要因素。基于此,从完善交通网络、强化景区联结、加强景区营销、缩小景区差异等方面提出了湖南省旅游流网络结构优化的对策建议。

The electrolyte-wettability at electrode material/electrolyte interface is a criticalfactor that governs the fundamental mechanisms of electrochemical reactionefficiency and kinetics of electrode materials in practical electrochemicalenergy storage. Therefore, the design and construction of electrode materialsurfaces with improved electrolyte-wettability has been demonstrated to beimportant to optimize electrochemical energy storage performance of electrodematerial. Here, we comprehensively summarize advanced strategies and keyprogresses in surface chemical modification for enhancing electrolytewettabilityof electrode materials, including polar atom doping by post treatment,introducing functional groups, grafting molecular brushes, and surfacecoating by in situ reaction. Specifically, the basic principles, characteristics,and challenges of these surface chemical strategies for improving electrolytewettabilityof electrode materials are discussed in detail. Finally, the potentialresearch directions regarding the surface chemical strategies and advancedcharacterization techniques for electrolyte-wettability in the future are *** review not only insights into the surface chemical strategies forimproving electrolyte-wettability of electrode materials, but also provides strategicguidance for the electrolyte-wettability modification and optimization ofelectrode materials in pursuing high-performance electrochemical energy storagedevices.

Naturally abundant transition metal oxides with high theoretical capacity have attracted more attention than commercial graphite for use as anodes in lithium-ion batteries. Lithium-ion battery electrodes that exhibit excellent electrochemical performance can be efficiently achieved via three-dimensional （3D） architectures decorated with conductive polymers and carbon. As such, we developed 3D carbon-supported amorphous vanadium oxide microspheres and crystalline V203 microspheres via a facile solvothermal method. Both samples were assembled with ultrathin nanosheets, which consisted of uniformly distributed vanadium oxides and carbon. The formation processes were clearly revealed through a series of time-dependent experiments. These microspheres have numerous active reaction sites, high electronic conductivity, and excellent structural stability, which are all far superior to those of other lithium-ion battery anodes. More importantly, 95% of the second-cycle discharge capacity was retained after the amorphous microspheres were subjected to 7,000 cycles at a high rate of 2,000 mA/g. The crystalline microspheres also exhibited a high-rate and long-life performance, as evidenced by a 98% retention of the second-cycle discharge capacity after 9,000 cycles at a rate of 2,000 mA/g. Therefore, this facile solvothermal method as well as unique carbon-supported and nanosheet-assembled microspheres have significant potential for the synthesis of and use in, respectively, lithium-ion batteries.

Dear Editor,Adult cutaneous wounds typically result in deficient regenera-tion due to abnormal fibro-proliferative responses.1 The scarring,while conducive to preventing extended infection and loss of nutrients at the injury site,can be troublesome.2 In contrast,wound healing in embryos showes lower levels of inflammation and a remarkable capacity for remodeling.3 Interestingly,the capability of fetal scarless healing is *** contrasted with the near-normal healing after the injury that occurs in the early gestational period(embryonic day 16,E16),wound healing in late gestation(embryonic day 18,E18)has prominent *** mechanisms responsible for this transition are largely unknown.
