    近年来,创新、供应链、可持续性这三个独立命题已有一定的研究基础且呈现高速发展的趋势,但目前将三个主题有机结合起来探讨可持续的供应链创新机制研究还是非常少见。在实践创新过程中,企业往往需要考虑供应链利益相关方的需求,在追求经济效益的同时,承担起一定的社会责任和环境责任。因此,迫切需要针对可持续的供应链创新机制,特别是其影响因素及过程展开深入研究。 本文基于社会资本理论,采用定性分析与定量分析相结合,理论分析与实证分析相结合的思路展开研究。首先,本文完善和提炼了可持续的供应链创新的准确概念及其特征。其次,确定了影响供应链创新因素的维度划分和测量工具,并采取问卷调查的方法研究和探讨了供应链社会...Recently, there have many researches related to innovation, supply chain management and sustainability respectively. However, the research on the intersection on innovation, supply chain management and sustainability is still rare. In practice, the company must consider all needs from different stakeholders in order to take their social and environmental responsibilities while continuously innovat...学位:管理学博士院系专业:管理学院_技术经济及管理学号:1772011015357

    随着时代的发展,以及我国国际化的步伐越来越快,英语作为一门国际通用语言已经越来越受到人们的重视,成了中国学校普遍开设且学程最长的科目。除了两亿多学生之外,还有难以数计的成人乃至幼儿在学习英语。虽然说自改革开放以来,我国的英语教育取得了长足的进展,但社会各个阶层对英语的教育和培训需求越来越大,公办教育体系所提供的英语学习机会越来越不能满足人们日益高涨的英语学习需求,因此就有了近年来五花八门的英语培训班的出现,而且逐渐形成产业化和规模化的英语培训市场。 据专家预测,2007年国内英语培训市场的市场总值大约是150亿元,全国的英语培训机构总数量达到了50000家,到2010年我国英语培训市场总值将...Nowadays, with the rapid economic development, China has more and more communication with other countries.

    胶原蛋白肽金属螯合物是胶原蛋白肽与金属离子通过配位共价结合或吸附结合方式形成的螯合物。该螯合物作为金属矿物元素补充剂,具有生物利用率高、安全性高、生物活性高等优点。综述了胶原蛋白肽金属螯合物的螯合机理、稳定性、吸收利用、功能活性和生产制备工艺并展望了其开发应用前景,以期为相关研究提供参考。Collagen peptide metal chelates are formed by collagen peptides and metal ions through coordinate covalent bonding or adsorption binding. They have been considered as the potential approach to delivering metal mineral elements to consumers with many virtues, such as higher bioavailability, higher safety and higher bioactivity. Chelate mechanism, stability, absorption and utilization, functional activity and production technologies of collagen metal chelates were reviewed and the development prospect were also foreseen in this paper, which was expected to provide reference for related reasearches.国家自然科学基金项目(41106149;41676129)资助

    石灰石粉与不同矿物掺合料复掺对高强自密实混凝土性能的影响

    基于混凝土的自密实性能和强度试验结果,研究了石灰石粉分别与粉煤灰、矿粉和硅灰3种不同矿物掺合料复掺组合对高强自密实混凝土性能的影响。结果表明:在合适的掺量范围和复配合比例条件下,将低活性的石灰石粉与高活性的硅灰复掺有很好的互补效应,对混凝土的自密实性能和强度产生了积极影响;石灰石粉与矿粉复掺不仅可以改善混凝土的自密实性能,同时也能满足高强要求。石灰石粉与硅灰、石灰石粉与矿粉复掺组合是制备高强自密实混凝土的有效技术手段。石灰石粉与粉煤灰复掺虽然显著提高了混凝土的自密实性能,但是不能满足高强要求,只能制备中、低强度自密实混凝土
