Analysis and Design of Fire Fighting and Rescue Command System for Urban Fire Control Integration

随着城市人口的不断增长，城市的消防工作日益重要。城市作为人类各个生活和生产要素的载体，公共消防安全不确定和非传统性因素日益增多，火灾机率和风险不断增加；社会、经济、科技、文化快速发展与公共消防基础建设、管理水平相对滞后的矛盾，社会防控火灾能力与人民群众日益增长的消防安全需求不相适应的矛盾还很突出。火灾隐患大量存在，火灾形势仍十分严峻。因此，城市消防部队灭火救援指挥工作面临着巨大挑战。 当今社会是高度信息化的社会，消防一体化建设可以将消防部队灭火救援工作的各个部分连接在一起，保证灭火救援工作更加及时有效展开。本论文以某消防支队灭火救援指挥工作为背景，采用面向对象的方法对灭火救援指挥系统进行系统...With the growth of the urban population, the fire control work plays a very important role. The city is a supporter for social production and livelihood, public fire safety in uncertain and non-traditional factors is increasing number of fire probability and risk is increasing. The rapid development of social, economic, science, technology, culture are contradict to public fire management lagging ...学位：工程硕士院系专业：软件学院_软件工程学号：X201323228

Comparative Study on Sports News in English——A Stylistic Perspective Based on 2012 London Olympics Reports by China Daily and New York Times

报纸是新闻的载体，是人们获得信息的重要来源。在阅读英语新闻时，人们发现，英语国家和中国所出版的报纸存在共同点，但是差异也是显而易见的。然而，针对中国和英语国家英语报纸的比较研究不多。那么，二者的相同与差异有哪些？引起这些差异的原因又是什么？针对这些疑问，本文对《中国日报》和《纽约时报》中的体育新闻的文体特征进行了对比研究。 本研究从2012年伦敦奥运会的报道中选取了16篇文章、8组分别针对同一事件的新闻报道，从普通文体学理论框架出发，用量化和定性分析的方法，就形式、词汇、句法和语义层面对两份报纸的文体特征进行比较，得出他们的共同点和差异性。研究发现，从宏观上看，两份报纸的文本在文体上相近，但...Newspaper, as carrier of news, is an important source of how people obtain information. While reading English news, people constantly feel that there exist similarities between newspapers published in English-speaking countries and those in China, but the differences are also to be reckoned. However, researches aiming at comparing English newspapers in China and English-speaking countries are few....学位：文学硕士院系专业：外文学院_外国语言学及应用语言学学号：1232011115258

Monitoring of immiscible phase enzyme-catalyzed process in microfluid chip by Raman microscopy

生物酶的研究对生命现象本质的揭示具有极其重要的意义。通常生物酶反应的研究是在水溶液体系中进行,与其在生物体内所处的水/有机两相界面微环境不相同。通过微流控芯片可获取稳定的水/有机相界面,并利用显微拉曼光谱仪进行微区扫描实现微流控芯片两相酶反应的检测。定量考察了氰根离子在微流控芯片中水相与苯胺相之间扩散行为,并检测了辣根过氧化物酶催化联苯胺与对甲基苯胺的聚合反应。结果表明,在芯片上,非极性分子联苯胺的酶催化反应产物结构组成较极性分子对甲基苯胺更为复杂,而在普通烧杯中的反应则观察不到这个现象。Enzyme catalyzed process is critical for revealing the virtual life.But normally enzymes were investigated in aqueous solution which quite different from the interface between water and organic molecules in vivo micro-environment.Here enzyme catalyzed reaction was carried out at the stable water/organic interface provided by the microfluidic chip,and Raman microscopy was used to monitor the reaction.The diffusion process of cyanide was investigated quantatively,and the polymerization process of benzidine and p-Toluidin were monitored.It was showed that different products from benzidine could be observed at various position in microfluidic chip,which did not happen in beaker or p-Toluidin system.国家自然科学基金资助项目(No.20675066);; 教育部留学回国人员科研启动基金资助项

北京市医药分开综合改革前后市属医院医疗收入结构变动度分析

目的：分析、评价中国北京市医药分开综合改革前后市属医院医疗收入结构情况及其变动度分析，为公立医院综合改革进程提供依据。方法：应用结构变动度和结构变动贡献率，从门诊和住院收入角度分析北京市市属医院医疗收入结构变化情况。结果：医药分开综合改革后门急诊人次数呈下降趋势，但门诊次均收入为8.25%；门诊收入和住院收入中均为诊察收入和药品收入的结构变动贡献率最大；门诊收入结构变动度大于住院收入结构变动度。结论：北京医药分开综合改革后门诊和住院收入结构有一定的改善，药占比下降，医务人员技术劳务价值得到了体现</jats:p
