综合需求响应(IDR)能够提升园区综合能源系统(PIES)的运行经济性、灵活性和可靠性,实现PIES供需双侧的协同效益。针对PIES实际运行中的IDR不确定性问题,提出了计及IDR不确定性的PIES优化运行模型。首先,分别建立基于消费者心理学原理的可转移电负荷和可替代负荷响应不确定性模型。然后,根据热用户温度感知模糊性和采暖建筑物热惯性,建立计及光照强度不确定性的可调节热负荷响应模型。在此基础上,以综合能源聚合商总收益最大为目标,构建计及IDR不确定性的PIES优化运行模型,并采用强化区间线性规划法进行求解。算例仿真结果表明,IDR能够有效提高系统运行经济性以及可再生能源消纳水平,并且考虑IDR不确定性能够更客观真实地反映IDR的作用效果,为PIES运行策略制定提供辅助决策。

晶态合金在人类发展史上占据了数千年的历史,不过近年来,非晶合金由于具有更高的强度、韧性、耐腐蚀性、耐磨性和生物兼容性,在生物医学工程领域展现出更广阔的应用前景。然而,由于非晶合金处于亚稳态,热稳定性较差,而纳米结构的引入可以通过原子弛豫降低界面自由能,增强非晶材料的热稳定性,同时可以提高表面与细胞的有效接触面积,增强其生物相容性。因此,纳米结构与非晶材料的结合是解决块体非晶合金(BMG)应用局限性的一种有效方法。综述了BMG和纳米非晶(NG)的特点及其在生物医学中的应用,介绍了NG的优越性能以及主要制备方法,并将合金、BMG和NG在生物医学中的应用做了简单比较,展示了NG在生物医学一些特别领域的独特应用和光明前景。此外,就NG目前遇到的困难挑战和未来发展方向进行了展望。

为了探究微纳米粗糙结构对水泥混凝土基聚四氟乙烯(PTFE)超疏水涂层性能的影响。研究考虑了混凝土表面的粗糙结构及微米级金刚石、碳化硅、刚玉粉末与纳米级疏水二氧化硅粉末构筑的微纳米粗糙结构。利用接触角测量仪和扫描电子电镜(SEM)对各种粗糙结构下PTFE涂层的湿润性和微观形貌进行了表征。同时,还评价了涂层抗滑性和耐磨耗性。结果表明:两步法制备工艺,先构筑微纳米粗糙结构再修饰PTFE涂层,能获得最强超疏水性能。微米级与纳米级粉末复配使用效果最佳,且随用量增加而增强,推荐比例1∶1,粒径比控制在60~120倍间为宜。不同粗糙结构中,金刚石效果最佳,其次是碳化硅和刚玉,混凝土凿毛处理后其抗滑性均满足规范要求,采用湿轮磨耗仪在试件表面往复摩擦1 000次后也均可保持85%以上的疏水性。该研究深入揭示了微纳米粗糙结构对涂层性能的影响机制,可指导实用型高性能PTFE超疏水涂层的制备。
