《铅书》“永平采作之法”的内容为南宋吴绍古所撰,是关于铅山县绍熙元年至庆元四年间某年矿冶生产的撰述。该撰述最早出现在吴绍古所著铅山县志《永平志》,其成书时间不迟于嘉泰四年,但后来又有增修而书名不改,形成初版和增修版,而且... 详细信息

《铅书》“永平采作之法”的内容为南宋吴绍古所撰,是关于铅山县绍熙元年至庆元四年间某年矿冶生产的撰述。该撰述最早出现在吴绍古所著铅山县志《永平志》,其成书时间不迟于嘉泰四年,但后来又有增修而书名不改,形成初版和增修版,而且后者包含了前者的内容,《铅书》所引是出自《永平志》初版或是增修版中初版的内容,目前尚无法判断。该撰述对宋代矿冶研究具有重要价值,不仅可增进对铅山县各类矿冶生产的理解,更重要的是,一方面可补缺与阐释宋代矿冶生产技术资料,另一方面可深化对宋代矿冶诸问题的认识。

为研究层状珊瑚砂地基承载能力,基于极限分析上限理论,构建了适用于层状砂土的多块体破坏机构,推导了外力功率与内能耗散率的计算公式.采用序列二次规划优化算法,建立了层状珊瑚砂地基极限承载力的上限分析方法.通过与现有研究成果的对比分析,验证了所建立方法的有效性,所构建的破坏机构突破了现有分层地基破坏机构下层必须为黏土的局限.结果表明,当破坏机构穿过不同层状地层时,基于层状地基模型与均质地基模型计算得到的地基承载力和临界破坏机构有显著不同,因此有必要考虑不同分层性质.相比于地基载荷试验,所提出的上限分析方法通过调整不同地层土体参数,能够快速得到地基承载力上限值,为珊瑚砂地基设计提供参考.

随着我国社会主要矛盾的变化,第三次分配的重要性日益凸显,这对慈善事业的高质量发展提出了迫切要求。然而,从当前慈善行业的发展状况来看,现有专业人才数量、价值理念、组织能力以及职业认证和制度保障方面均无法满足行业发展的需求。慈善事业的可持续发展需要慈善教育的支持,高校应抓住我国“新文科”建设的机遇,构建慈善教育的学科体系。具体途径包括:明确学科的基本范畴;设置跨学科的专业课程体系;构建本土化的知识体系;组建更多元的师资队伍;搭建实践实训基地;倡导相关职业认证与政策支持。通过这些措施,可以进一步完善我国慈善教育的发展,并推动慈善事业迈向更高质量的发展。

近些年,科学技术已经渐渐发展成为国家与国家竞争过程中的核心,世界各国均开始高度注重科学研发工作,期望利用更多的科研成果来强化综合国力,以便在世界舞台上抢占主动权以及话语权,在该种时代背景下,科研经费管理成为一项重点工作。目前,科研是高等院校在发展过程中的一项重要任务,其中科研经费是否得到科学化管理不但与科研资金利用效率密切相关,甚至还会对科研工作成败与否产生直接影响。基于此,本文从财务视角切入,针对高校科研工作者、科研经费管理人员进行调查,汇总整理了H高校在2021年、2022年期间纵向课题科研经费预算,由此指出高校科研经费管理方面所存在的一系列现实问题,然后立足于中国高校科研经费管理工作现状,提出了针对性强、实施效果佳的优化对策,旨在进一步提高高校科研经费管理工作的科学性,为科研工作提供重要的经费保障,由此提高中国的科研水平。
