我国经济社会发展步入新常态,城市发展开启存量更新模式。居民绿地需求与绿地空间不足之间的矛盾日益凸显,已有研究证明,非正式绿地在城市建成环境中具有良好适应性,能够有效解决城市面临的一系列社会和生态问题,具备较大发展潜力。聚焦于绿地低供高需的城市区域,以福州市鼓台中心区为例,通过实地调研挖掘供需失衡区范围内可利用的非正式绿地资源。从时、空间可用潜力两个维度确定影响非正式绿地发展潜力的评价指标,建立多目标优化模型;引入帕累托前沿理论,利用Matlab中非支配排序遗传算法求解得出调研区域内对非正式绿地进行更新改造的多个解集的优先层级。最后基于综合评估结果和三种不同的场地类型提出非正式绿地的更新策略,为高密度老旧城区绿地的存量更新发展提供借鉴。

The strategic selection of appropriate preparation methods and binder strategies is crucial for enhancing the particle and combustion performance of pyrotechnic delay compositions (PDCs). This study, utilizing droplet microfluidics technology (DMT) and micron-scale raw materials, prepared spherical B/Pb 3 O 4 composite particles with varying concentrations of fluorine rubber (F 2604 ). The morphology, specific surface area, bulk density, flowability, friction sensitivity, thermal decomposition, and combustion performance of these microspheres were characterized. The results indicate that as the binder content increases, the particle size of the microspheres first decreases and then increases, the specific surface area decreases, and the bulk density increases, correlating with tighter binding of the reactant powders by the binder. Furthermore, tighter powder-to-powder binding results in a progressive decrease in the thermal decomposition peak temperature of the samples (from 404.2 degrees C to 346.4 degrees C). Additionally, increased binder content reduces the friction sensitivity and combustion rate of the samples, which is attributed to the energy absorption properties of the binder. Compared to the control group, the microsphere samples exhibit significantly enhanced bulk density, flowability, friction safety, and combustion delay precision, potentially improving the reliability of PDCs in ignition sequences.

森林康养产业是林业与健康养生融合发展的新业态,厘清森林康养基地的空间分布特征及驱动机制可有效指导森林康养基地的空间资源分配,促进康养产业可持续发展。本研究以福建省森林康养基地为例,采用计量地理分析方法对其空间布局进行实证分析,并借助地理探测器解析各驱动因素对森林康养基地空间分布的影响机理。研究结果表明福建省森林康养基地空间总体呈现“五核四点两带”的大聚集、小分散格局,其空间分布特征是各维度因素共同作用形成的结果,其中基地分布与旅游景区等资源分布呈正相关,而与区位交通、市场需求、社会经济维度驱动因子的分布存在部分空间错位。在此基础上,研究构建了福建省森林康养基地空间布局--驱动机理模型,并提出产业发展布局建议,以期为福建省森林康养产业的高质量可持续发展提供理论依据和技术支撑。

The structure-property relationship at interfaces is difficult to probe for thermoelectric materials with a complex interfacial microstructure. Designing thermoelectric materials with a simple, structurally-uniform interface provides a facile way to understand how these interfaces influence the transport properties. Here, we synthesized Bi2-xSbxTe3 (x = 0, 0.1, 0.2, 0.4) nanoflakes using a hydrothermal method, and prepared Bi2-xSbxTe3 thin films with predominantly (0001) interfaces by stacking the nanoflakes through spin coating. The influence of the annealing temperature and Sb content on the (0001) interface structure was systematically investigated at atomic scale using aberration-corrected scanning transmission electron microscopy. Annealing and Sb doping facilitate atom diffusion and migration between adjacent nanoflakes along the (0001) interface. As such it enhances interfacial connectivity and improves the electrical transport properties. Interfac reactions create new interfaces that increase the scattering and the Seebeck coefficient. Due to the simultaneous optimization of electrical conductivity and Seebeck coefficient, the maximum power factor of the Bi1.8Sb0.2Te3 nanoflake films reaches 1.72 mW m(-1) K-2, which is 43% higher than that of a pure Bi2Te3 thin film.

南朝梁武帝萧衍"素善钟律"①,自著《乐社大义》《钟律纬》《乐论》等乐书,今佚。后世辑考者据《梁书·乐志》《隋书·律历志》得补《乐社大义》《钟律纬》各一卷,但仍有遗珠。北宋陈旸所撰二百卷《乐书》,规制宏大,资料详赡,保存了大量已佚或少见于他书的音乐文献。其中有未见于他书的梁武帝不著书名律论十二则,是今见梁武帝直抒其律论思想的唯一遗文。该佚文解释了梁武帝的律学观念,不仅可补其乐著之阙,也是研究南朝礼乐制度与音乐思想的珍贵资料。
