The composite powders,Sn nanoparticles embedded into the porous hydrogel-derived carbon(Sn@PHDC),were successfully prepared by polymerization and calcination processes,and the characterization results confirmed that Sn nanoparticles were homogeneously dispersed in the porous hydrogel-derived pyrolytic *** coin cell assembled with the Sn@PHDC-50 composite electrode presented good cyclic stability and rate performance when the weight ratio of Sn nanoparticles to hydrogel-derived pyrolytic carbon was maintained at 1:***,the Sn@PHDC-50 electrode manifested a lower charge transfer resistance of 58.57 Ω and a higher lithium ions diffusion coefficient of 1.117×10^(-14) cm^(2)·s^(-1) than pure Sn and other Sn@PHDC *** improvements can be partly ascribed to the fact that the hydrogelderived pyrolytic c arbon matrix can release the volume strain and enhance the electronic conductivity of the composite electrode,and partly to the fact that the porous hydrogelderived pyrolytic carbon matrix can suppress agglomerations of Sn nanoparticles and shorten Li^(+) diffusion *** work may provide a new appro ach for the improvement of Sn-based anode materials for lithium-ion batteries.

Among all-solid-state batteries, rechargeable Al-ion batteries have attracted most attention because they involve threeelectron-redox reactions with high theoretic specific capacity. However, the solid Al-ion conductor electrolytes are less studied. Here, the microscopic path of Al3+-ion conduction of NASICON-type(Al0.2Zr0.8)20/19Nb(PO4)3oxide is identified by temperature-dependent neutron powder diffraction and aberration-corrected scanning transmission electron microscopy experiments.(Al0.2Zr0.8)20/19Nb(PO4)3shows a rhombohedral structure consisting of a framework of(Zr,Nb)O6octahedra sharing corners with(PO4) tetrahedra; the Al occupy trigonal antiprisms exhibiting extremely large displacement factors. This suggests a strong displacement of Al ions along the c axis of the unit cell as they diffuse across the structure by a vacancy mechanism. Negative thermal expansion behavior is also identified along a and b axes, due to folding of the framework as temperature increases.

对4个国内外花椒优良种质的雄株花粉生活力进行初步测定,并对6个不同种质花椒进行人工授粉,计算坐果率,了解不同种质间人工授粉对花椒坐果率的影响,探究授粉与花椒产量提升间的相关性,以期为椒农生产生活提供理论支持。以供试4个花椒种质的雄株花粉为试验材料,利用TTC染色法对不同条件及不同贮藏时间下花粉生活力进行测定。选取晴朗高温天气,随机选取6个供试种质雌株各100花序,记录花序中小花数量。坐果期记录果实数量,计算坐果率。结果表明,花粉生活力在不同品种间存在极显著差异(P≤0.01)。其中凤县花椒花粉生活力最低(2.03%),‘朝仓’花椒花粉生活力最高(55.98%)。花椒花粉最适贮藏温度为-80℃,且花椒花粉生活力随贮藏时间增加而逐渐下降。其中,凤县花椒耐贮性较差,‘朝仓’花椒耐贮性较好。对花椒进行授粉后发现,‘朝仓’花椒在未授粉时坐果率极低,坐果率提升最明显(80.43%)。在国内花椒中,凤县花椒坐果率提升较大(10.89%)。在花椒种间杂交试验中,‘朝仓’花椒花粉对其余品种花椒坐果率均存在抑制作用,国内花椒种质花粉对‘朝仓’花椒授粉时,‘朝仓’花椒不坐果。不同花椒种质的花粉生活力存在差异,但花椒属植物花粉生活力均处于较低水平。-80℃为花椒花粉最适贮藏温度,且花粉生活力随贮藏时间下降。花椒授粉后坐果率与花粉生活力关联性不显著,导致坐果率变化的具体原因仍需进一步分析。‘朝仓’花椒可能与国内花椒种质远缘不亲和,存在生殖隔离。

"天下不为尧存,不为桀亡","社稷无常奉,君臣无常位"。而天下得失的核心全在于"人",在于"民心"。在春秋战国这样一个"乱象"时代,各诸侯国为自身的政治利益诉求,不择一切手段,笼络人心,网罗天下人才。秦之所以在七国争霸中能独占鳌头、一统六国之天下,乃是他在人才荐用上善于以"权变"的思想,以"权变"的方法,满足人的社会性需求,高于六国一筹。然而,以"我"为中心的功利实用主义人才荐用观毕竟不是长久之计,特别在政治利益诉求获取之后,这种劣根性就会凸显。秦的兴旺过程深刻地诠释了得民心、人才者得天下,失民心、人才者失天下的永恒不变的真理。它将会给我们一个深刻的启示与鉴戒。

【目的】探讨口服降糖药二甲双胍对高血压患者左心室肥厚(LVH)的影响。【方法】分析307例原发性高血压患者的临床及超声心动图检查资料,其中高血压合并糖尿病且服用二甲双胍治疗6月以上者110例(A组),高血压合并糖尿病未服用二甲双胍治疗者97例(B组),单纯高血压组100例(C组)。【结果】3组之间一般临床资料包括年龄、性别、体质量指数、病程、血压水平、血脂、肾功能、主要用药情况等无明显差别;A组和B组空腹血糖水平明显高于C组,而A组和B组之间空腹血糖及糖化血红蛋白(HbAIc)水平无明显差异。各组左心室舒张末期内径(LVEDd)及左心室收缩功能(射血份数,EF)无明显差异,与B组及C组相比,A组患者室间隔厚度(IVST)、左心室后壁厚度(LVPWT)、左心室质量指数(LVMI)明显降低(P<0.05);LVH发生率分别降低41.6%及34.4%(P<0.05);E/A比值明显减小,舒张功能不全(E/A比值<1)发生率明显下降(P<0.05)。【结论】二甲双胍可能改善了高血压患者左心室重构,减轻心肌肥厚,改善左心室舒张功能不全。值得进行前瞻性、随机对照的临床研究进一步明确这种效应。
