The Research on Financial Innovation of Small and Middles-sized Enterprises-- Practical Experiences from China Merchants Bank

中小企业是我国国民经济的重要组成部分。在当前“大众创业、万众创新”的新形势下，中小企业更是获得了蓬勃发展。促进中小企业发展，是保持国民经济平稳较快发展的重要基础，是关系民生和社会稳定的重大战略任务。 但一直以来，困扰中小企业发展的“融资难、难融资”这个问题虽然都在探索、但始终未能有效地、系统地解决。当前，经济发展进入了新常态，面对“大中企业融资脱媒、利率市场化和资本监管强化”所带来的新挑战，如何做好中小企业服务既是商业银行响应政府号召的需要，也是自身业务持续发展的现实需求。金融创新是解决这个难题的有效途径。 本文旨在探索新形势下商业银行如何做好中小企业金融创新，从而更好地促进中小企业的发展...As one of the important component of Chinese national economy, small and middle-sized enterprises (SMEs) have experienced vigorous development under the new situation of mass entrepreneurship and innovation. To promote the development of SMEs has become the important foundation to maintain the stable and relatively rapid growth of national economy and has become the major strategic task related to...学位：工商管理硕士院系专业：管理学院_工商管理硕士(高级管理人员工商管理硕士)学号：X200815606

Preparation of potassium diformate by methyl formate and potassium hydroxide

联系人：李清彪. 第一作者：詹国武（1986—），男，学士.[中文文摘]本研究采用甲酸甲酯、氢氧化钾、甲酸为原料，一步反应制备二甲酸钾。系统地考察了影响产品收率的主要因素，优化了工艺条件，结果表明，当n(MF)/n(KOH)=1.20，n(HCOOH)/n(KOH)=1.44，反应时间为30min，反应温度为55℃时，二甲酸钾产品收率可达 98.8%。产品经红外光谱分析及成分测定，符合质量标准。[英文文摘]In this study, methyl formate, potassium hydroxide and formic acid were used as raw materials for one-step synthesis of potassium diformate. The main factors affecting the quality and yield of product were investigated. The optimal conditions for reaction were: molar ratio of MF to KOH 1.20:1, molar ratio of HCOOH to KOH 1.44:1, reaction time 30 min and reaction temperature 55℃. The product met the quality standard of potassium diformate after infrared spectrum analysis and composition determination.厦门大学创新性实验计划资助项

Determination of the number of ψ(3686) events taken at BESIII

The number of ψ(3686) events collected by the BESIII detector during the 2021 run period is determined to be (2259.3±11.1)×106 by counting inclusive ψ(3686) hadronic events. The uncertainty is systematic and the statistical uncertainty is negligible. Meanwhile, the numbers of ψ(3686) events collected during the 2009 and 2012 run periods are updated to be (107.7±0.6)×106 and (345.4±2.6)×106, respectively. Both numbers are consistent with the previous measurements within one standard deviation. The total number of ψ(3686) events in the three data samples is (2712.4±14.3)×10^
