Study on the Effect of Financial Development on High-tech Enterprises’ Financing Constraints

高新技术产业作为一个国家新的经济增长点，已成为各国相互竞争的关键领域。在政府大力扶持下，我国高新技术产业有了很大发展，但仍存在很多阻碍其发展的不利因素。其中，融资约束是当前我国高新技术企业急需解决的主要问题。因此，探讨融资约束的影响因素对于促进高新技术企业发展有着重要的意义。 金融系统是企业重要的外部环境之一，那么金融发展对高新技术企业的融资约束是否有影响呢？基于这样的思考，本文从金融规模、金融中介效率和股票市场发展三个方面分别度量金融发展，以2006-2012年沪深高新技术上市公司的面板数据为样本，利用修正的现金-现金流模型研究金融发展对高新技术企业融资约束的影响。为了更深入分析金融发展对...As a new point of national economic growth, high-tech industry has become a key field of mutual competing between countries. High-tech industry in China has made significant progress with the government’s strong support, but there are still many negative factors that hinder its development. For high-tech enterprises, Financing constraints is the main problem which needs to be resolved in time. The...学位：经济学硕士院系专业：经济研究所_产业经济学学号：2902012115206

“物理化学实验”课教学效果提升探讨

物理化学实验是一门理论性、实践性和技术性较强的基础化学实验课程之一。目前,\"物理化学实验\"教学存在着学生理论知识不够扎实、教学内容陈旧、教师教学方法单一、缺乏创新性实践性教学等问题。要提升实验课的教学效果,就必须结合专业特点,牢固专业理论知识掌握,丰富教学内容,采用多样化教学,培养学生创新能力和实践应用能力。2017年厦门大学教学改革研究项目JG20170222;;国家基础科学人才培养基金项目J1310024;;2016年度教育部“基础学科拔尖学生培养试验计划”研究课题资

Application of Fuzzy Control in Intelligent Traffic Lights Monitoring System

为了解决拥挤的城市交通问题,针对交通灯监控系统中可变的交通状况,提出一种基于模糊算法的监控系统。应用模糊算法,通过模糊控制实现交通灯的控制,使道路通畅。对监控系统进行分析,合理选择模糊控制器的结构,根据动态的车流量,通过模糊算法分配当前车道的通行时间,并全面考虑同时通行的各种车道组合。该监控系统提高了车辆通行效率,使道路更为通畅。与传统的固定配时系统相比,它更适于当前纷繁复杂的交通状况。In order to solve the crowded transportation problem of cities,in view of the variable traffic condition in the traffic lights monitoring system,proposed to use the fuzzy algorithm and the fuzzy control to realize the control of the traffic lights.Making the analysis to the monitoring system,selected the fuzzy controller structure in reason.It assigned the pass time of each traffic lane through the fuzzy algorithm according to the dynamic volume of vehicle.In the paper it has considered all kinds of traffic lanes combination pass through in the same time.The monitoring system enhanced the efficiency of vehicles traffic,caused the path to be more unobstructed.Compared with the traditional fixed timing systems,it is more suitable to the complexity of current traffic conditions

一种基于微电极的珊瑚共生体光补偿点测定方法探讨

珊瑚虫与虫黄藻互利共生形成共生体,虫黄藻通过光合作用为珊瑚虫提供重要的能量来源。珊瑚共生体的光补偿点可以较好地指示珊瑚的光适应性,是重要光合特性指标,但其测定方法鲜有报道。利用溶氧微电极结合光强可调节光源,以鹿角杯形珊瑚为实验材料,依据扩散平衡理论,建立了一种造礁石珊瑚的光补偿点的测定方法。实验结果表明珊瑚的扩散边界层溶氧浓度会快速响应光强变化。珊瑚扩散边界层溶氧浓度与光合有效辐射具有较好的相关性,且光强由高降低过程测得的相关系数更高。实验测得鹿角杯形珊瑚的光补偿点较低,为1.52μE/m~2/s,与喜阴植物的光补偿点相当。相对较低的光补偿点利于珊瑚栖居于水深范围更广的区域,有助于扩展珊瑚的生态位。溶氧微电极相关技术和方法在珊瑚光合作用研究中具有广泛的应用前景。中国科学院战略性先导科技专项A(XDA13020300)国家自然科学基金(41676163; 41406191; 41276113; 41276114)国家重点研发计划(2017YFC0506301,2018YFC1406500)广州市珠江科技新星(201806010017
