为降低建筑楼宇的能源消耗,研究建筑集群中的多个建筑楼宇共享冷热电联供系统、热能存储装置以及电池时的能源调度优化问题.考虑到建筑楼宇的能源需求和能源价格具有随机性,并且每个建筑楼宇以各自的费用最小化为目标,从随机规划和多目标的角度,建立建筑集群供能系统的两阶段多目标随机规划模型.为了提高模型的求解效率,提出将线性规划松弛与Benders分解算法相结合,从而获得建筑楼宇共享能源系统的Pareto最优解集.算例分析中通过CPLEX软件求解,对比分析不同随机因素对最优化建筑集群供能系统总费用以及建筑楼宇各自费用的影响程度,结果表明了所提出算法的有效性以及所构建的模型可以有效提高最优化决策的准确性.

The rich phase behavior of block copolymers(BCPs)has drawn great attention in recent ***,the double diamond(DD)phase is rarely obtained because of the competition between the minimization of interfacial energy and packing ***,a rod-coil BCP containing mesogen-jacketed liquid crystalline polymer is designed to acquire ordered bicontinuous network *** reduction of internal energy originating from the orientational interaction among the rod blocks can compensate for the free energy penalty of packing frustration to stabilize the DD *** resulting BCP can also experience lamellae-to-DD and double gyroid-to-lamellae transitions by changing the annealing *** results make the rod-coil BCP an excellent candidate for the self-assembly of ordered network structures,demonstrating great potential in nanopatterning and metamaterials.

The development of anode materials with high rate capability and long charge-discharge plateau is the key to improve per-formance of lithium-ion capacitors(LICs).Herein,the porous graphitic carbon(PGC-1300)derived from a new triply interpenetrated co-balt metal-organic framework(Co-MOF)was prepared through the facile and robust carbonization at 1300°C and washing by HCl *** as-prepared PGC-1300 featured an optimized graphitization degree and porous framework,which not only contributes to high plateau capacity(105.0 mAh·g^(−1)below 0.2 V at 0.05 A·g^(−1)),but also supplies more convenient pathways for ions and increases the rate capability(128.5 mAh·g^(−1)at 3.2 A·g^(−1)).According to the kinetics analyses,it can be found that diffusion regulated surface induced capa-citive process and Li-ions intercalation process are coexisted for lithium-ion ***,LIC PGC-1300//AC constructed with pre-lithiated PGC-1300 anode and activated carbon(AC)cathode exhibited an increased energy density of 102.8 Wh·kg^(−1),a power dens-ity of 6017.1 W·kg^(−1),together with the excellent cyclic stability(91.6%retention after 10000 cycles at 1.0 A·g^(−1)).

预警原则作为一种新颖的环境资源管理手段,其对海洋渔业资源养护的有效性已为一些国际协定和国外立法所确认。适用预警原则应满足以下条件:存在不确定危险;遵循成本收益分析原则、比例原则和非歧视原则;并定期检查、适时调整。目前我国海洋渔业资源管理工作也面临着内外双重压力,有必要在未来制定一部《海洋生物资源养护和管理法》。而当务之急是尽快修订现行《渔业法》,将预警原则确定为我国海洋渔业资源管理的基本原则;同时,还应通过建立综合性海洋管理部门、大量搜集科学信息、拓展群众参与途径、以及根据各海域的具体情况,有针对性地实施预警原则,促进我国海洋渔业资源的可持续利用。
