    P2P网络借贷平台凭借其独特的优势,拓宽了借贷交易的可能性边界,降低了借款人的融资成本,提高了投融资效率。此外,P2P网络借贷平台在引导民间借贷规范化发展、构建多元化资本市场及助推利率市场化改革等方面也发挥了积极作用。作为正规金融机构的补充,P2P网络借贷平台为小微企业开辟了新的融资渠道,有助于缓解小微企业融资难问题。然而,由于政府监管缺失、征信制度建设滞后、投融资者的非理性等原因,造成我国P2P网络借贷平台的“野蛮生长”。违规违法问题平台层出不穷,给投融资者带来了重大损失,并由此引发了P2P网络借贷平台的信任危机。基于此,本文从政府监管、规范我国P2P网络借贷平台发展和投融资策略等三个方面提...By means of its unique advantages, P2P lending platform broadens the trading possibilities frontier of debit and credit, reduces the financing costs of borrowers, and improves the efficiency of both investment and financing. Furthermore, P2P lending platform has also played a positive role in guiding the standardized development of the private lending, building a diversified capital markets, and b...学位:金融硕士院系专业:经济学院_金融硕士学号:1562013115213

    水稻是重要的粮食作物之一,全球一半以上的人口以大米为主食。随着世界人口的增长,人们正面临着越来越严重的粮食危机。如何增加水稻产量一直是作物育种以及植物学研究的重要目标。近年来水稻遗传育种工作者发现了一些成熟期叶片的叶绿素不降解或仅少量降解而使叶片仍保持绿色的持绿型水稻品种,研究发现其叶片持绿性状多数属多基因控制的数量遗传,少数属隐性主效基因控制的质量性状遗传,相关基因大多已被鉴定及克隆。迄今为止,尚未见穗枝梗持绿性状的研究报道。佳辐占系本课题组育成的优质高产早稻品种,已在生产上大面积推广应用,该品种在成熟期穗枝梗仍保持绿色,为了解其穗枝梗持绿性状的遗传机理,本研究以佳辐占(持绿性)和明恢215...Rice is a very important crop as staple food of more than half of the population in the world. With the increasing of the world's population, people are facing serious food crisis. Increasing rice yield has become an important target in crop breeding and plant research. Recently, some rice varieties or germplasms characteristic of stay-green leaves have been identified. The chlorophyll of these va...学位:理学硕士院系专业:生命科学学院_微生物学学号:2162013115250

    Impact Resistance Evaluation of Pier Structures Subject to Corrosion in Marine Environments

    考虑大量桥梁未设置安全岛或其它类型的防撞设施,桥墩客观存在着船撞的风险,并可能因为船撞产生局部破坏甚至整体倒塌。与此同时,桥梁还不可避免地受到腐蚀引起的性能退化,特别是海洋环境下钢筋混凝土桥梁出现的腐蚀劣化问题尤为突出。目前对于旧桥的抗冲击性能评估,鲜有学者考虑结构腐蚀劣化带来的影响,这可能造成评价结果偏于不安全。因此,有必要细致考虑腐蚀因素对桥墩柱性能的影响,在此基础上,进一步分析墩柱腐蚀对其抗冲击性能的影响。 本文首先根据结构腐蚀劣化的机理及其对桥墩柱结构的危害,确定结构腐蚀退化因素,量化结构性能退化程度;然后通过选取合适的损伤评估指标,结合模拟船桥接触碰撞的数值算法,建立了一套腐蚀桥墩...Since a large number of bridge piers are not equipped with anti-collision facilities, these piers are subject to the risk of ship-bridge collision that may lead to a partial damage or even a totally collapse. Meanwhile, these bridges are also inevitably suffer performance degradation due to corrosions, especially for those located in the regions of marine environments. However, few study evaluate ...学位:工学硕士院系专业:建筑与土木工程学院_桥梁与隧道工程学号:2532013115180

    揭示了土工布提高加筋土强度的力学机理.假设:平行、分层布置的土工布在垂直布面方向是连续分布的;土工布是薄膜,不影响物料的力学特性:土工布、物料、加筋土的变形是相同的:加筋土的应力状态是土工布与物料二者应力状态的叠加;加筋土的破坏只发生在物料中.提出了土工布单元,给出它与加筋土单元、物料单元间变形受力关系.结论:土工布承担了拉力,削弱了物料分担的荷载,提高了加筋土的强度;据此,可以设计出土工布的最佳布置方案
