孵化器与风险投资“联姻”:障碍分析与策略选择

虽然在理论上孵化器与风险投资存在较多的互补性,但总体而言,两者的合作并没有取得实质上的进展。本文对双方“联姻”中存在的障碍进行了较详细的分析,指出缺乏合作动力和双方自身的一些缺陷是影响“联姻”的主要障碍;在剖析两者主要的“联姻”方式特点的基础上,提出了当前孵化器应该采用练好内功,创造条件,循序渐进地引入风险资本的观点。国家软科学研究计划(2004DGQ1D110

Symbiosis of Culture and Geographical——The Minnan Rhymes Cultural Center Program Design as an Example

本文以厦门闽南童谣文化中心方案为例,通过介绍该方案在传承闽南文脉、优化具体功能要求和控制轴线关系等方面的设计思考,以及在构造细节、材料方面的关注,旨在研究批判的地域主义在当代建筑多元发展的形势下,如何结合传统地域文化特色,对稍显冷漠的现代主义进行修正和回应,进而对文化中心类型的建筑如何运用批判的地域主义思想,将现代空间与传统文化的结合进行有益的探索。Taking "Xiamen Minnan Tongyao Culture Center" project as an example, through introducing the scheme's design concept in inheriting minnan context, optimizing the specific functional requirements and controlling axis relations, and the attention of the detail constructions and material aspects, thus to discuss how to use Critical Regionalism to combine traditionalregional culture characteristics in the diversified situation of development, to modify and response to the slightly aloof modernism.Further more, we can carry on the beneficial exploration of how to apply the idea of critical regionalism to modern space as well as traditional culture to cultural buildings

Application of a Variable-universe Fuzzy PID Controller for DC Motor Speed Control System

基于PId控制与模糊控制各自的优点,将模糊控制与常规PId控制相结合,并运用变论域的方法,设计了变论域自适应模糊PId控制器.然后,以直流电机为模型,实现对其转速的控制,使用MATlAb进行可行性研究,并将其仿真结果与PId控制和模糊控制的仿真结果进行比较.结果表明,基于直流电机的变论域自适应模糊PId控制器的控制效果明显优于常规PId控制和模糊控制.Fuzzy control and conventional PID control were combined in this paper;meanwhile,the method of variable universe was adopted.In this paper,a variable-universe and self-adaptive fuzzy PID controller was designed and utilized in a DC motor model to achieve the speed control of the DC motor.This paper used the tool of Matlab to complete this system's feasibility study and compared the simulation results with the PID control and fuzzy control's simulation results.The results showed that the control performance of the variable-universe and self-adaptive fuzzy PID controller was obviously better than PID control and fuzzy control

Empirical Discrimination of the Survival Prospect of Start-up High Technology Firms

如何判别初创科技型企业未来的生存前景是各种投资机构和理论界都极为关注的问题。运用非条件Logistic回归模型,对厦门留学人员创业园内初创企业的生存状态进行了经验判别。在12个影响因素中,发现有3个因素与初创企业的生存状况密切相关。其中,既有的销路和明确的目标市场是促进初创企业成活率提高的因素,而产品适用范围的扩大反而会降低初创企业的生存概率。How to discriminate the survival and development prospect of start-up hi-tech firms is an issue highly concerned by both venture capital institutions and theoretical circles.The research paper uses non-conditional logistic regression model to make empirical discrimination about the survival and development status of start-up hi-tech enterprises registered in Xiamen Pioneering Park for Overseas Chinese Scholars.It is found that among the 12 factors of empirical discrimination,there are three key factors that are closely related to the survival status of start-up businesses.Ready-to-use Marketing and sales channels and clearly defined target market can effectively increase the survival ratio of start-ups,whereas the extension of the product's application scope can also decrease the survival probability of them.国家软科学研究计划项目“科技企业孵化器发展模式及运行机制研究”的阶段成果之一,项目编号:2004DGQ1D11

页岩气开发风险及风险治理——两次专题研讨会总结

美国页岩气革命使得美国实现了能源自给，带动了全球油气工业的发展，改变了世界能源供应格局。但随着美国页岩气的不断开发，各种风险也逐渐凸显，同时，在相关预算收紧的情况下，管理能力正在下降或变得不完整。在这种背景下，为全面认识与页岩气开发相关的风险及其管理中的一系列社会问题和决策问题，美国国家研究理事会（NRC）成立的指导委员会在2013年的5月和8月分别组织相关专家召开了研讨会，对页岩气开发面临的风险及风险治理问题进行了深入分析。 《页岩气开发风险及风险治理》一书是美国国家研究理事会项目主任保罗&middot;C&middot;斯特恩基于两次专题研讨会上的主题报告人和评论专家等的发言整理而成。该书分为&ldquo;非常规页岩气开发风险&rdquo;和&ldquo;页岩气开发风险治理&rdquo;两大部分、共20章，对页岩气开发风险的讨论主要从公众对页岩气开发风险的态度以及页岩气开发面临的运营风险、水资源风险、空气风险、生态风险、公共健康风险、对气候变化的影响、对开发区的影响、各种风险间相互作用等方面来展开，而对风险治理讨论则涉及管理内容、政府职责、政府能力、管理技术、设立试点区、公众和利益相关者参与、安全文化等方面。这些讨论与认识，对美国和其他页岩气开发国以及计划开发页岩气的国家认识页岩气开发的风险及对其实施有效管理将具有重要的参考意义。</p

Experimental Study on Enhancement of Ammonia Bubble Absorption Process by Adding Nanoparticles

From the Danckwerts theoretical surface renewal model of mass transfer,an approach using nanoparticles to enhance ammonia bubble absorption process was examined in this study.In our experiment,the ammonia vapor flow flux and the concentration ratio of bulk ammonia solution were adjusted and their effects on ammonia bubble absorption were explored.The experimental results show that the absorption ratio was significantly increased by adding Al2O3 nanoparticles in the bulk solution,and the effective absorption..

Comparison of uncut Roux-en-Y anastomosis and traditional Roux-en-Y anastomosis in the totally laparoscopic distal gastrectomy for gastric cancer: An analysis of multiple centers' data

目的对比非离断式(Uncut)Roux-en-Y吻合和传统Roux-en-Y吻合应用于全腹腔镜远端胃癌根治术后消化道重建的安全性和短期疗效。方法回顾性分析国内10家单位共60例远端胃癌根治术后全腹腔镜消化道重建的胃癌病人临床资料,根据消化道重建方式不同分为Uncut Roux-en-Y组(Uncut组)34例,传统Roux-enY组(传统组)26例。结果 Uncut Roux-en-Y吻合在消化道重建时间方面用时更短[(51.5±13.3)min vs.(80.4±16.2)min,P=0.000],出血量更少[(60.0±35.6)m L vs.(132.9±65.1)m L,P=0.000],且在进食半流饮食时间方面具有优势[(4.6±1.5)d vs.(7.2±2.3)d,P=0.000]。两组病人在留置胃管时间、术后排气时间、进食流质时间和术后住院时间方面差异无统计学意义。两组病人均无围手术期死亡病例,并发症发生率差异无统计学意义(8.8%vs.7.7%,P=0.875)结论 Uncut Roux-en-Y吻合和传统Roux-en-Y吻合应用于全腹腔镜下消化道重建安全可行,Uncut Roux-en-Y吻合在重建时间和控制出血量方面具有优势。Objective To compare the security and short-term effect of the digestive tract reconstruction during the totally laparoscopic distal gastrectomy for gastric cancer between the Uncut Roux-en-Y anastomosis and the traditional Roux- en- Y anastomosis. Methods The clinical data of 60 gastric cancer patients with digestive reconstruction underwent totally laparoscopic distal gastrectomy between December 2012 and June 2015 in 10 domestic hospital were analyzed retrospectively. According to the difference of digestive reconstruction,it can be divided into the Uncut Rouxen-Y anastomosis group with 34 patients and the traditional Roux-en-Y anastomosis group with 26 patients. Results In uncut Roux-en-Y anastomosis group,the operative time in digestive reconstruction was shorter[(51.5±13.3)min vs.(80.4±16.2)min,P=0.000]; the intraoperative blood loss was less[(60.0±35.6)m L vs.(132.9±65.1)m L,P=0.000];semi-liquid diet time was earlier[(4.6±1.5)d vs.(7.2±2.3)d,P=0.000]. However,there was no difference between the two groups on nasogastric tubegastrointestinaltwo groups on nasogastric tube,gastrointestinal transit,fluid diet and the duration of postoperative hospital stay. Both groups had no death case during the perioperative period and there was no significant statistical difference in the postoperative complication rates(8.8% vs. 7.7%,P=0.875).Conclusion The Uncut Roux- en- Y anastomosis and the traditional Roux-en-Y anastomosis are both safe and feasible for the digestive reconstruction under the totally laparoscopic distal gastrectomy for gastric cancer. Besides,the Uncut Roux- en- Yanastomosis has other advantages such as less reconstruction time and less bleeding.广东省科技计划项目(No.2014A020212591

疼痛的中西医理论概述

疼痛是与组织损伤或潜在的组织损伤相关的一种不愉快的感觉和情感体验。西医学方面,痛觉理论从闸门控制理论、内外侧通路理论演变到痛觉矩阵理论,近年来大脑的神经网络对痛觉信息的编码亦受到广泛关注。中医关于疼痛的认识经历了五个发展阶段,痛证理论逐步确立。近代以来中医学家不断加以整理和完善,对痛证"不通则痛"和"不荣则痛"的病机进行了深入探讨,对痛证各种治法方药进行总结归纳,并借助现代医疗技术从细胞、分子和基因水平对痛证进行了研究。本文从中西医的角度分别论述疼痛的理论及相应的研究成果,以期对未来痛觉的理论发展及中西医结合临床治疗提供理论基础
