An Analysis of Chinese Private Entrepreneurs’ Image in People’s Daily based on framing theory

改革开放三十年，我国取得了举世瞩目的发展成就，其中民营经济功不可没。民营企业家作为一个独具中国特色的经济概念，成为我国向公有制经济为主体，多种所有制经济共同发展经济格局转变的关键一环。一方面，他们是改革的推动者和见证者；另一方面，他们又处于改革风暴和各种矛盾的中心。媒体对于民营企业家的报道不光在于引导这个群体的发展，也有助于群众接纳他们，进而理解变革。因此，民营企业家报道的研究，对探讨社会转型期的媒体宣传有着重要的意义。 本文以《人民日报》为研究对象，选取改革开放三十年来民营企业家相关报道进行研究，试图结合历史背景，探寻《人民日报》报道民营企业家的方式、所呈现出的媒介形象以及其他结论。论文绪...Chinese private economy has contributed a lot to China’s great achievement since the reform and opening-up in 1978. And the Chinese private entrepreneurs exclusively have played an indispensable role to form the present economy pattern, which is named joint development of multiple economic elements with the economy of public ownership as the main body. On the one hand, they are promoters and witne...学位：文学硕士院系专业：新闻传播学院新闻学系_新闻学学号：3062007115242

Development of the facility for model scramjet testing

A hypersonic propulsion test facility has been constructed in IMCAS (Institute of Mechanics, Chinese Academy of Sciences) in order to provide a high enthalpy hypersonic flow for a model scramjet testing. The vitiated air is produced by a hydrogen/air and oxygen replenishment combustion heater with flow rate of 3.5kg/s, total pressure of 5MPa and total temperature of 2000K in maximum, and accelerated up to Mach 5.6 by a two-dimensional nozzle. Test chamber of the facility is evacuated by a one-stage central air ejector. The preliminary facility performance tests showed that the vitiated air heater could provide the high enthalpy flow as expected. A copper model scramjet without cooling is ready for testing. © 2001 The American Institute of Aeronautics and Astronautics Inc. All rights reserved

Hypoglycemic action of acidic polysaccharide in leaf of Gynura divaricata and its effect on related indexes

与西药相比,传统中药及其提取物具有经济、安全的优点,同时还可避免西药的许多副作用[1]。中药材白子草又名白背三七,为菊科(COMPOSITAE)三七属(gynurA CASS.)植物白子菜〔gynurA dIVArICATA(lInn.)dC.〕的干燥叶,具有清热、舒筋、止血、祛痰等功效[2]。在民间,白子菜的茎和叶可药食两用,用于治疗高血压、糖尿病和高血脂症等[3],其化学成分复杂,目前已分离获得多糖类[3]、黄酮类[4-6]、生物碱[4,7-8]和脂肪酸[9]等成分。Gynura divaricata acidic polysaccharide( GDAP) was extracted and purified from dry leaf of Gynura divaricata( Linn.) DC.Effects of successive lavage GDAP for 0,7,14 and 21 d with daily dose of 15,37 and 60 mg·kg- 1on blood glucose content of diabetic model mice were analyzed,and differences in SOD activity and MDA content in serum and glycogen content in liver of mice were compared.The results show that with prolonging of successive administration time and increasing of GDAP daily dose,blood glucose content of diabetic model mice generally appears the decreasing trend.With successive administration for 14 and 21 d,blood glucose content of different GDAP treatment groups is generally lower than that of CK group( 0.9% Na Cl injection with daily dose of 10 m L·kg- 1) but higher than that of T1group( metformin with daily dose of 200 mg·kg- 1).In which,after successive administration GDAP for 21 d with daily dose of 37 and60 mg·kg- 1,blood glucose content of diabetic model mice is significantly or extremely significantly lower than that of CK group but significantly or extremely significantly higher than that of T1 group,while SOD activity in serum of diabetic model mice is significantly higher and its MDA content is significantly lower than those of CK group,but there is no significant difference with those of T1 group.Glycogen content in liver of diabetic model mice of different GDAP treatment groups is higher than that of CK group,but lower than that of T1 group.It is suggested that GDAP is the main hypoglycemic components in polysaccharide of G.divaricata leaf, and it has dose-effect relationship in hypoglycemic activity.Hypoglycemic mechanism of GDAP is probably related to improving antioxidant enzyme ability in the body,enhancing activity of scavenging oxygen free radicals,relieving liver damage,and increasing glycogen storage capacity.福建省自然科学基金资助项目(2012J01400

电针“梁门”-“足三里”对急性胃黏膜损伤模型大鼠血清代谢物动态表达的影响

目的采用核磁共振氢谱技术(1H NMR)探讨电针梁门-足三里治疗急性胃黏膜损伤的可能作用机制。方法 54只SD大鼠随机分为正常组、模型组、电针组,各组又分为干预1、4、7天3个时间点,每个时间点6只。除正常组外其余各组采用75%乙醇灌胃法复制急性胃黏膜损伤大鼠模型。造模成功后电针组大鼠用鼠板捆绑固定,采用疏密波(4 Hz,50 Hz),电针"梁门"(负极)"足三里"(正极),每次30 min,每日1次。正常组和模型组大鼠用鼠板捆绑固定30 min,每日1次。分别于干预1、4、7天后光镜观察胃黏膜病理形态,检测大鼠血清1H NMR谱,并利用模式识别方法分析不同干预时间下代谢物谱的差异,用正交偏最小二乘判别分析(OPLS-DA)模型和独立样本t检验,以P <0. 05筛选潜在的生物代谢标志物。结果病理结果显示,正常组大鼠胃黏膜表面细胞完整,未见溃疡性损害。干预1、4天时模型组大鼠可见胃黏膜上皮结构破坏严重,毛细血管增生及出血;干预4天时电针组大鼠胃黏膜的黏膜结构恢复较为完整,较模型组明显改善。血清代谢组学结果显示,正常组与模型组分离出差异代谢物6个:甘油磷酸胆碱、谷氨酰胺、甜菜碱、葡萄糖、乙酸盐和胆碱。与模型组比较,干预1天时电针组胆碱、甘油磷酸胆碱、葡萄糖、乙酸盐、谷氨酰胺和甜菜碱均升高;干预4天时胆碱、葡萄糖、谷氨酰胺和甜菜碱升高,甘油磷酸胆碱和乙酸盐降低;干预7天时甘油磷酸胆碱降低,葡萄糖、乙酸盐、谷氨酰胺和甜菜碱升高,胆碱无明显变化。结论电针"梁门"-"足三里"可有效回调急性胃黏膜损伤大鼠血清相关差异代谢物,恢复相应代谢通路稳定,以电针4天效果最佳,可能是其逆转胃黏膜损伤的作用机制之一。国家自然科学基金(81473751);;深圳市科技计划(JCYJ20160406140612883

目的:观察艾灸干预胃溃疡大鼠胃黏膜相关脑肠肽的动态表达,探讨艾灸干预胃溃疡的时效关系。方法:SD大鼠72只随机分为3批,各批分为正常组、模型组、胃经穴位组和非经穴位组(n=6)。采用70%乙醇灌胃复制胃溃疡大鼠模型。胃(非)经穴位组的大鼠进行艾灸1、4、7d(30min/d)。干预结束后于光镜下观察胃黏膜形态,RT-PCR测定胃黏膜增殖细胞核抗原(PCNA)及P物质(SP)表达。结果:与正常组比较,模型组大鼠胃黏膜溃疡灶明显,胃黏膜PCNA表达降低(P<0.05),SP表达升高(P<0.05);与模型组比较,干预1d后胃经穴位组大鼠胃黏膜PCNA表达升高(P<0.05),干预4d后胃经穴位组PCNA表达升高(P<0.05),SP降低(P<0.05);干预7d后各组大鼠胃黏膜PCNA及SP表达无显著差异。结论:艾灸胃经穴位能有效调节相关脑肠肽指标,促进胃黏膜损伤修复,并具有一定的时效关系。深圳创新科技计划项目(No.JCYJ20160406140612883);;国家自然科学基金项目(No.81473751);;国家重点基础研究发展计划(973计划)(No.2015CB554502)~

CSCW 软件模型 SOWER 的设计及其实验系统 SOWERMail 的实现

本文在全面考察了计算机支持的协同工作（CSCW）和群件（groupware）这一研究领域的基础上提出了一个软件模型 SOWER 并实现了一个实验系统 SOWERMail。SOWER 具有三层树状结构，从上到下依次由 supervisor 、organizor 和 worker 组成。通过将通信与协调工作从其他模块分开，SOWER 模型试图构造一个能根据群体中的个人的实际需要而构筑本地系统，从而更好的适合群体需要的生产群件的方法。为此，本文详细描述了 SOWER 模型的底层结构以及其工作过程，并在实验系统 SOWERMail 中以最常用的群件－电子邮件－为例，作了初步尝试。最后，作为作者研究计算机支持的协同工作的体会，本文还讨论了几个当前与该领域有关的热门话题，并对它们提出了自己的看法。This thesis presents a software model called SOWER and implements an experimental system called SOWERMail after a survey of the academic field—Computer- Supported Cooperative Work (CSCW) and groupware. SOWER consists of treelike three layers with agent-based components named supervisor, organizer and worker, respectively. Through the separation of communication/coordination components from those deal with real jobs, we try to sketch a system that can be customized according to the requirement of single user in group/groups. To support this idea, infrastructures and functions of each component, and the construction procedure of SOWER software, are carefully described. Besides, in the trial system—SOWERMail, by developing an electronic mail client according to SOWER, we made the model alive tentatively. At last, we proposed our own ideas to several currently hot debates as what we have learned from the research

Huaqiangbei: The Epitome of Industry Development and Transformation in Shenzhen

改革开放短短40年，深圳GDP增长超过了1万倍。深圳产业转型和创新贯穿在深圳40年的发展历程中，华强北则是深圳产业发展与转型的缩影。40年前，华强北街道是深圳一条再普通不过的街；在中国改革开放的浪潮下，华强北从平地崛起，逐渐发展成为世界闻名的“中国电子第一街”。 华强北是如何探索和发展起来的呢？在发展过程中，华强北经历了几次产业升级和市场转型？然而，“盛极必衰”，曾经因“山寨手机”迎来爆发式增长的华强北，在电子商务、移动互联网技术迅速发展的情况下迅速面临困境，华强北应该如何应对新的挑战并找到新的业绩增长点呢？In the past 40 years of reform and opening up, Shenzhen's GDP has grown more than 10,000 fold. Huaqiangbei is the epitome of the industrial transformation and innovation that Shenzhen has seen in the last 40 years of development. Forty years ago, Huaqiang North Street was an ordinary street in Shenzhen. Due to China's reform and opening up, Huaqiang North gradually developed from a flat piece of land into the world-famous "China's first electronics street". How did Huaqiangbei explore and develop? In the process of development, how many industrial upgrades and market transformations did the company experience? But all things that rise must eventually fall, even the explosive growth that Huaqiangbei experienced as it went from “no-name phone brands” during the rapid development of e-commerce and mobile Internet technology. With difficulties piling up, how should Huaqiangbei cope with new challenges and find new areas of strong growth
